What is a Carburetor Rebuild?

Let’s face it, no matter how precisely you take care of your vehicle, the carburetor is prone to gumming up over time. This buildup of gunk can clog the carb or even find its way into the engine.

What’s more, the carburetor internals, especially the gaskets and seals can also age, which causes various malfunctions.

To avoid these issues, it’s wise to clean or even rebuild the carburetor from time-to-time.

But before we drill into the details, we have to define what a “carburetor rebuild” means exactly.

In a nutshell, rebuilding a carburetor means replacing its internal components, completed by a thorough cleaning. Based on the number of parts replaced we can distinguish between partial and full carburetor repairs.

Let’s get down to the nitty-gritty a look at your options when it comes to carb repair and maintenance:

1. Cleaning
2. Partial rebuild
3. Full rebuild
4. Replacement

1. Cleaning

There’s no question that cleaning is the cheapest and easiest carb maintenance available. This process requires you to pull the carb out, take it apart, and soak the parts in a bath of eco-friendly carb cleaner.

This simple process helps remove the buildups from the carb and restore its former performance.

2. Partial Carb Rebuild

Unfortunately, a simple cleaning is sometimes not enough to get the carb in good shape.

This is because the needles and jets are prone to completely clogging if too much dirt gets into them. What’s more, the gaskets and O-rings also age over time.

This is where a partial carburetor rebuild comes into play.

As the name suggests, a partial carb rebuild means replacing the defective internal components, but not all of them. These parts typically include the O-rings, gaskets, needles, and jets.

To manage this maintenance, you have to invest in a “partial carb rebuild kit” (a.k.a. “carburetor repair kit”). These affordable kits are sold for almost every type of carb regardless of their age or type.

Just dismantle and clean the carb, but when it comes to reassembling, you can install the new parts from the kit. It’s as simple as that!

3. Full Carb Rebuild

Unlike a partial rebuild, a full carb rebuild requires you to replace every internal part of the carb. Keep in mind that a full carb rebuild is only necessary if you notice a lot of wear on the major parts like the throttle shaft.

For a complete carb rebuild, you will need a “full carb rebuild kit,” which includes all of the necessary components. These kits typically include needles, jets, O-rings, gaskets, diaphragm, air screw, springs and clips, screws, and metal washers.

Just make sure to double-check the description of the kit before you order it to make sure it includes all the required parts. The exact composition of the kits varies widely depending on the make and type of kit.

Also, if your vehicle features more carburetors, you will need more kits of course.

4. Carb Replacement

Sometimes it makes sense to replace the entire carburetor instead of completely rebuilding it. If the throttle shaft has too much play or the plates have worn into the carburetor body, it could be a sign that the entire carb has to be replaced.

Surprisingly, new carburetors are often affordable since they are designed for mass production and sold in large quantities.

Replacing your old carb for a new one is a lot faster and easier than cleaning and rebuilding the old one. A complete rebuild can be especially tiring if you have more than one carb.

Consequently, you may want to consider replacing the carbs instead of completely rebuilding them.

How Often Should You Rebuild Your Carburetor?

How often should I rebuild my carburetor? – we get this question more often than not.

Although there’s no specific time recommendation for carburetor cleaning and rebuilding, the general rule is that the less often you use your vehicle, the more often its carb needs to be cleaned or even rebuilt.

This is because when the engine sits for an extended period of time, the fuel starts to gum and clog the carbs.

The type of fuel is no less important. Today’s gasoline contains ethanol, which deteriorates the rubber components like seals, gaskets, and the float.

On top of that, the required carb maintenance interval depends on many other factors like the type and design of the carbs, and the way you use the vehicle.

Nevertheless, here are some tips to get some idea of when you should clean or even rebuild your carbs:

• If your vehicle has been sitting for months or even a longer period, its carbs have to be cleaned or partially rebuilt (if necessary).
• If your vehicle is rarely used, it’s recommended to clean (or even partially rebuild) the carbs annually, before each season. Typical examples are vintage cars and auxiliary outboard motors.
• A partial rebuild is always recommended if you have regular carb issues or certain parts show signs of wear.
• A full carb rebuild or a replacement is only necessary if you notice a lot of wear on the major parts.
• Especially on 2-stroke engines, a yearly carb cleaning and inspection never hurts. Keep in mind that many 2-stroke engines blow because of lean running carburetors, so keeping them in good shape is like having extra insurance.
• Note that not each component of the carb is changeable, meaning that in some cases you have no choice but to invest in a new carb.

Are Carburetors Hard to Rebuild?

Rebuilding a carburetor is considered simple routine maintenance, but it requires some time and patience. The difficulty of the work strongly depends on the design and the number of carburetors since the arrangement and the complexity of these units vary widely.

For example, lawnmower carburetors typically feature a fairly simple design, while high-performance powersport vehicles have much more complex carbs.

For example, certain ATVs and snowmobiles come with special safety features (like Yamaha’s T.O.R.S. system) which adds some complexity to the carbs.

We won’t even mention electronically controlled carburetors, which are more difficult to maintain and rebuild than their regular counterparts.

Can You Rebuild a Carburetor Yourself?

You can rebuild a carburetor even by yourself if you have the required tools and a clean, well-lighted place to work comfortably. Best practice is to manage this maintenance on a table where you can sit down.

Besides the above, you will need an appropriate carburetor repair kit, cleaner liquid, rugs, paper towels, and a small container to soak the parts in.

Beware that you will need a lot of patience as you will have to pay attention to the details and cleanliness.

If you are not mechanically inclined, you may want to get the job done by a professional. Keep in mind that after reinstalling the carb you will also have to adjust it for optimal performance.

This process can be tricky if your engine features more carbs since they have to be synchronized, which requires some expertise.

Is it Worth Rebuilding a Carburetor?

Sometimes it’s worth completely rebuilding a carburetor, while in other cases a replacement is a better choice. This strongly depends on the type of carbs you have, the price of a full rebuild kit, and a complete carb, and the value of your time of course.

How Much does it Cost to Have a Carburetor Rebuilt?

As a rule of thumb, rebuilding carburetors cost about $10-$100 per carb if you do the work yourself. A partial carb rebuild kit costs about $10-$20 per carb, while the prices of complete kits range from $20 up to $100. You will also need a can of carb cleaner liquid, which may cost you about $5-$10.

Therefore, you can partially rebuild a simple carb for a couple of bucks, while a complete rebuild of four complex carbs may cost you more than $400.

If you want to get the work done by a service shop, don’t forget to budget for the cost of labor.

Carburetor Rebuild Kits

Let’s take a closer look at carburetor rebuild kits!

Are all carb rebuild kits the same?

If you are considering rebuilding your carbs, keep in mind that not all carb rebuild kits are the same.

The design of carbs varies from one model to the next, so each carb has its own rebuild kit. What’s more, you can often find different kits for the same carb, which contain different components.

The cheapest carb rebuild kits are usually partial rebuild kits that contain only a few components. On the other end of the spectrum, you can find full rebuild kits that come with everything you need for a complete carb rebuild.

Sometimes you can find “middle-level” kits that fit between these two worlds.

How do you know which carburetor rebuild kit to buy?

To figure out which carburetor rebuild kit you need, you should check your vehicle’s owner’s manual. The manual clearly describes the exact type and model of your carburetor.

If the manual isn’t available, you can also identify your carb by the list number stamped on the side of the carburetor’s body.

Based on this number and your vehicle’s year and specs, you can get the exact type of your carb from part catalogs or online databases.

Can carburetor gaskets be reused?

If the gaskets are in a good condition you can reuse them without any problems.

Conclusion

If you use your vehicle regularly, you can run it for many years without rebuilding the carburetor. However, a thorough cleaning before each season is always a good idea to remove the potentially accumulated gum from the carb.

Rarely used vehicles typically require at least an annual cleaning, or often a partial carb rebuild. This maintenance includes replacing the O-rings, gaskets, needles, and jets.

It’s also wise to partially rebuild the carb on vehicles that have been sitting for a long time.

A full carb rebuild is only necessary if there’s significant wear on the major parts.

If you are not mechanically inclined, you can get your carbs rebuilt by a service shop. Your other option is investing in a new carb, which can be a worthy alternative to a full carb rebuild.

What is a Polaris VES Engine?

Polaris VES engines feature the Polaris-exclusive Variable Exhaust System. As the name suggests, this system utilizes guillotine exhaust valves intended to increase engine power and throttle response. As a rule of thumb, the VES system can increase engine power by about 6-10 HP depending on the size of the engine and its features.

Polaris revealed its innovative VES system in the late ’90s, but VES Polaris snowmobiles became more prevalent in the early 2000s.

It’s safe to say that Polaris’ VES does the same job as Yamaha’s YPVS (Yamaha Power Valve System) and Ski-Doo’s RAVE (Rotax Adjustable Variable Exhaust) systems.

Let’s get down to the nitty-gritty and talk about how the Polaris VES works!

What Does a Polaris Variable Exhaust System (VES) Do?

Non-VES Polaris engines are regular 2-stroke engines in which the exhaust fumes exit the cylinders via regular exhaust ports. These ports can be designed to produce a great performance at either high or low engine RPMs, but not both.

Because of this, the ports on regular non-VES engines have compromised engineering to produce an acceptable performance at all RPM ranges.

This is where the VES system comes into play since this feature is designed to change the size of the exhaust ports at the right time. Therefore, VES engines do a really good job in both low and high RPM ranges.

How does the Polaris VES system work?

In a nutshell, a Polaris Valve Exhaust System (VES) features guillotine slide valves operated with bellows. These valves are mounted on the exhaust ports and opened and closed based on the engine RPM.

On early VES sleds, these valves were controlled by the pressurized exhaust gases, but on later models they are controlled by solenoids.

At low engine RPM, the VES valves stay closed ensuring better combustion and less unburned fuel in the exhaust gases. This increases torque and power in low and mid-RPM ranges.

At higher RPM, the valves start moving and the exhaust ports open up, which creates a high-ported engine characteristic. In other words, the opened exhaust ports allow the engine to breathe easier ensuring higher RPM, more torque, and power.

Therefore, contrary to popular belief, Polaris VES engines generate more peak HP than their non-VES equivalents!

Drawbacks?

One of the main cons of the VES system is that it adds more complexity to the engine. And the more features an engine has the more things there are that can go wrong!

What’s more, VES valves require annual cleaning and inspection, which means more complex maintenance and higher running costs.

It’s also good to know that certain Polaris sleds were released with aluminum valves. These valves are prone to melting during aggressive rides since VES assemblies lack any cooling system.

These aluminum VES valves have to be replaced with more durable ones for higher reliability and durability.

Which Polaris Snowmobiles Feature VES?

The first Polaris snowmobile with a VES engine was the 1997 Polaris XCR 440. Since this machine was a race sled, only a limited number of them were made.

The VES became commercially available in 1998, but they were still only on the 440 twin engine.

In the following years, VES valves found their way to the larger engine categories including 500, 600, 700, and 800cc classes. However, the manufacturer kept many non-VES models in its fleet as well.

As a reference, here’s a list of some popular VES Polaris snowmobiles:

• 1997 Polaris 440 XCR
• 1999 Polaris XCR 700
• 2000 Polaris 500 XC SP
• 2000 Polaris 600 XC
• 2001 Polaris 440 Pro X
• 2002 Polaris 800 Edge X

How do You Identify Polaris VES Engines?

You can identify a Polaris VES model by taking a closer look at the engine. The valves are enclosed in metal nests that are covered by a black plastic cap. These VES valve assemblies are mounted on the side of the cylinders close to the cylinder head.

Here’s a great video on how to locate VES valves on a Polaris sled:

Can You Add VES to a Polaris Snowmobile?

Although you can add VES valves to most non-VES engines, keep in mind that it’s not an easy modification.

Despite that it’s just a bolt-on upgrade, installing VES valves requires you to add and modify a lot of parts and features.

For example, VES engines have slightly different exhaust systems. Also, the ECU has to be reprogrammed or even replaced for a VES engine in order for the valves to operate properly.

Without the ECU upgrade, the engine couldn’t get the most out of the revamped engine characteristics. This also means that you would have to adjust the carbs to match them to the new ECU.

What is a Polaris VES Oil?

VES engines not only require more care and attention, they also need a special full-synthetic oil to run properly. As the name suggests, Polaris VES oils are specifically formulated for VES 2-stroke engines. According to the manufacturer, the key advantages of these lubricants are as follows:

• Maximum engine protection
• Easy starting in extreme cold
• Improved rust and corrosion inhibitor package
• Full synthetic base oil formulation offers excellent load carrying abilities to reduce engine wear
• Provides enhanced valve cleanliness, low smoke & excellent lubricity
• Designed for Variable Exhaust Systems & all other Polaris® 2-cycle engines

What Color is Polaris VES oil?

The color of Polaris VES oil depends on its type and formulation. As an example, Polaris VES Gold oil features a golden color.

Takeaways – What is VES on Polaris?

Simply put, the VES (Variable Exhaust System) is the power valve system of 2-stroke Polaris engines. These valves are intended to change the size of the exhaust ports to get the most out of the engine in each RPM range.

VES valves are nestled on the exhaust ports and open and close based on the engine’s RPM. This causes the engine’s power band to change, which helps increase torque, power, and throttle response.

Thanks to this feature, Polaris VES engines provide better performance and especially in the low and mid-RPM ranges. Also, they offer slightly more top-end power.

The major drawback of VES valves is that they add complexity to the machine and require annual cleaning and inspection.

Should a Snowmobile Track Make Some Noise?

According to Snowest.com, about 50% of snowmobile noises are generated by the track.

Riders are prone to considering these noises to be exhaust or engine sounds, but they are often wrong.

Unlike their vintage predecessors, today’s advanced snowmobile engines and exhaust systems generate much less noise. Therefore, the tracks seem much louder on these machines due to the engines and pipes being much quieter.

This means that a certain amount of track noise is considered normal on snowmobiles.

The level and nature of track noise depends on a variety of factors like the track’s design, material, and features.

Some tracks are louder than others, even if they come from the same manufacturer. What’s more, track noises often depend on the type and make of the sled.

New tracks also tend to be slightly louder as they are very stiff and usually stored in a twisted position and so need a couple of miles to loosen up.

However, certain track noises are caused by malfunctions, e.g. the track is rubbing against the idler wheels or jump on the track drivers.

Let’s get down to the nitty-gritty and talk about the most common causes in detail!

8 Reasons Why Your Snowmobile Track is Making Noise

1. Snow and Ice Buildups

One of the most common sources of track noise is when the track rubs against buildups of snow and ice in the tunnel.

Ice buildups can even create a “bridge” between the two sides of the tunnel. If the lugs reach these buildups they can generate various sounds and a lot of vibration.

What’s more, the ice can block the heat exchanger, which often leads to engine overheating.

Best practice is to stop and carefully check the tunnel. If buildups are present, remove them manually or lift and gently drop the rear end of the sled a couple of times.

2. Wrong Track Tension or Alignment

It’s safe to say that the leading reason why a snowmobile track is generating noise is track misalignment. Only a little misalignment can cause the track to move side-to-side, rubbing against the sides of the idler wheels.

Along with the track’s alignment, the tension is no less important.

A snowmobile track that is too tight often produces a clicking noise, while a loose track makes a rattling noise when it slams against or even jumps on the drivers.

Therefore, it’s recommended that you check and adjust the track tension and the alignment if needed.

Don’t rely on your eyes when it comes to these settings! Instead, read your sled’s manual and follow the manufacturer’s recommendations.

3. Worn Out Drive Sprockets

The track is prone to slipping on the drive sprocket if their teeth are worn down.

The most common symptom of this issue is when the track generates ratcheting noises at top speed or aggressive accelerations.

These plastic sprockets are mounted on the driveshaft nestled in front of the track. Inspect them carefully and replace them if they are worn!

4. Lugs Hitting the Heat Exchanger

Another common issue is when the lugs or studs reach the heat exchanger or the bottom of the tunnel.

This not only produces annoying sounds but can also wear down or break the lugs and even damage the heat exchanger.

There could be many reasons why the lugs are hitting the exchanger, but the most common ones are as follows:

• Loosened track
• Lugs (or studs) are too long
• Wrong rear suspension settings
• The sled is overloaded
• Poorly designed or positioned heat exchanger
• Lack of tunnel protector

5. Idler Wheel and Bearing Issues

You should also check the idler wheels and the bearings in the skid.

If the idler wheels touch the track for some reason they tend to make excessive noise, just like defective or seized bearings. Bad rear wheel bearings allow the track to move side-by-side, rubbing it against the front wheels.

Grease or replace the bearings in the skid if needed. Also, don’t forget to check the drive shaft bearings.

6. Damaged/Worn Out Slides

When it comes to the track noises of snowmobiles, the slides (hyfax) are often overlooked.

Worn out, loosened, or even wrong-sized slides can cause various sounds since the track can’t run smoothly on them.

First, make sure that the slides aren’t worn out, bent, or loosened.

If you’ve recently replaced your slides, make sure that you didn’t cut them too long.

Some owners prefer to bevel the rear end of the slides to reduce track noise. This helps the track to run more smoothly and prevent it catching on the slides when you move the sled backward.

7. Clips and Studs Issues

Snowmobile track clips are small metal units integrated inside the track. They are designed to slide against the hyfax (slides).

In most cases, they last as long as the life of the track, but they can get cracked or bent when hit by a rock or other hard objects.

Damaged snowmobile clips often cause various noises and wear out the slides much faster, so they have to be replaced immediately.

If you want to find out more about the process, here’s a great tutorial on how to replace snowmobile track clips.

If your track is studded, don’t forget to check the studs as well. The most common problem with studded tracks (if studs are on their outer portion as well) is the studs hitting the guides causing wear and tear.

As we’ve discussed, studs can even reach the heat exchanger, which translates to strange noises and hefty repair bills.

8. Worn Out Track

A snowmobile track is considered a wear item, so you can see more and more cracks, tears, exposed cords, and missing parts on it over time.

Not necessarily, but worn-out snowmobile tracks can also be louder than its newer counterparts.

If you notice significant damage or wear and tear on your track, maybe it’s time to replace it.

+1 – Other Issues

Although the source of the strange noises is often the track on a sled, other units can also make various sounds. The most typical of which are the following:

• Clutch
• Belt
• Chaincase (sprockets and chain)
• Drivers
• Driveshaft
• Jackshaft
• Bearings
• Suspensions

If you can’t figure out what’s causing the sound, you may want to pull these units apart and check them carefully. Sometimes it’s just a flat spot on the belt or a missing tooth on one of the gears.

Takeaways

Why is my snowmobile track making a clicking noise? – this is a common question of many riders.

If the track generates clicking noise, it’s often caused by the clips hitting the slides due to the track being too-tight.

If you want to fix this issue it’s wise to check the track tension and alignment as the first steps.

In other cases, the noise is caused by some ice buildups in the tunnel, worn-out drive sprockets, idler wheels, or slides. Bearings are also prone to getting seized or damaged, producing various noises.

The lugs and the studs are also prone to hitting the bottom of the tunnel or the heat exchanger on liquid-cooled sleds.

If you can’t find the source of the noises, don’t forget to check some other parts like the chaincase, clutch, drive gears, and the suspensions.

If you are looking for an Arctic Cat snowmobile fault code list, this post is for you. We at PowerSportsGuide have compiled them under one roof!

Arctic Cat Snowmobile Fault Codes

Without further ado, the official Arctic Cat snowmobile fault codes of post-2020 models and their meanings are as follows:

Arctic Cat Snowmobile Fault Code List (2-Stroke)

Arctic Cat Snowmobile Fault Code List (4-Stroke Turbocharged)

Disclaimer: These charts are for informational purposes only! For the exact codes, please check your sled’s service manual.

How to Read Arctic Cat Snowmobile Fault Codes

Checking the codes on these charts can only give you a basic idea of your sled’s malfunction. If you want to find out more about the issue, you have to dig deeper and read the fault code using diagnostic-specific software. How can you do that?

As a rule of thumb, you can read the fault code on an Arctic Cat snowmobile in two different ways. One of your options is to transport the machine to a dealer who can read the fault codes for you. Your other choice is to buy an OEM or aftermarket snowmobile diagnostic software.

These special diagnostic tools contain software, diagnostic hardware, and cables to connect your sled to a laptop. Unfortunately, these tools come with very hefty price tags, and they are often only compatible with specific models.

This is because you can only find diagnostic ports on modern Arctic Cat sleds. In contrast, older sleds can tell you the fault codes with a flashing LED light. Let’s move on and see how it works!

Arctic Cat Flash Codes

Older Arctic Cat snowmobiles feature a control LED on their dashboard to display the fault codes. The number, duration, and sequence of the flashes can tell you the exact code.

When you turn the ignition key on the sled, the LED flashes once, which is considered normal as it’s a kind of self-diagnostic feature. But anything more than this initial flash would be a fault code.

In a nutshell, the flash codes for the majority of Arctic Cat snowmobiles are as follows:

• 1 = Open or short circuit in TPS (throttle position sensor)
• 2 = Open or short circuit in water temp sensor
• 3 = Open or short circuit in intake air temp sensor
• 4 = Open or short circuit in the barometric pressure sensor
• 5 = Injector failure
• 6 = APV Servo motor failure
• Steady flash/Constant on = Overheating issues

(Keep in mind that these codes might be different on some specific models!)

How to Clear Arctic Cat Snowmobile Fault Codes

If you’ve fixed the problem on your sled, the fault code should disappear when you turn the ignition off and restart the sled. If the code doesn’t stop appearing on the screen this indicates that the problem still exists or one of your sensors is broken.

However, if it’s a “hard” code, the only way to clear it is to take the sled to a dealer who can hook it up to a laptop and eliminate the code with the diagnostic software.

Therefore, if you can’t clear the fault code by restarting your sled, best practice is that you contact your dealer!

How to Read Yamaha Snowmobile Fault Codes

Checking the fault code on this chart can only give you a basic idea of the issue. So, if you want to dig deeper, you need to read the fault code with a unique type of software that provides you with a tremendous amount of information on the malfunction.

Generally speaking, you can read the fault codes on your Yamaha snowmobile in two ways. One of your options is to take your sled to an authorized dealer who can read the fault codes for you. If you don’t want to transport your sled to a dealership, your other choice is to invest in diagnostic software.

Let’s drill into the details and see how it works!

Reading Fault Codes on Modern Yamaha Sleds

If you have a modern Yamaha sled with onboard diagnostic ports, you can read the fault codes with a unique tool, known as Y.S.D.T. (Yamaha Snowmobile Diagnostic Tool). As the name suggests, this tool is designed to test and diagnose the computer and related components on Yamaha snowmobiles.

The Y.S.D.T. tool can provide you very valuable information such as:

• Fault codes (a.k.a. DCT – Diagnostic Trouble Codes)
• EFI (Electronic Fuel Injection) data
• Sensor data
• Engine controller identification information
• Offline and online capability
• Live updates

The diagnostic tool comes as a kit with the software and interface hardware, including the diagnostic cable and the harness. How do you set it up?

1. As a first step, you have to install the software on a computer, to which the sled’s diagnostic port has to be connected.
2. Next, plug the diagnostic cable’s receiver end into the Y.S.D.T. interface hardware, then plug the other end of the cable into the diagnostic connector of the sled.
3. As a final step, you have to connect the interface hardware to the computer with a USB cable.
4. If the software is running, a window will appear when you connect the cable to the machine.

Once you’ve logged into the software, you can find out about the malfunction and conduct some tests on your sled.

Besides the Y.S.D.T, if you do your research you may find some aftermarket snowmobile diagnostic tools that are compatible with your sled.

Reading Fault Codes on Vintage Yamaha Sleds

If you have an older Yamaha sled that doesn’t feature diagnostic ports, it won’t be compatible with the Y.S.D.T. tool. But don’t worry, as older sleds feature a built-in system designed to inform you about the fault codes.

The fault codes are only displayed on the dashboard or through the check engine light on these sleds. This means that on most older machines, the check engine light is designed to flash in a specific sequence that can give you the fault code.

To decode the flashing check engine light, you should check your sled’s manual.

Here’s an example how a flashing fault code looks on a Yamaha snowmobile:

How to Clear Yamaha Snowmobile Fault Codes

If you have the problems on your sled have been repaired, you probably want to know how to clear the fault codes without taking your sled to the dealer.

For your convenience, we’ve listed a step-by-step guide on how to clear Yamaha snowmobile fault codes:

1. Hold the Reset and the Select buttons down.
2. Turn on the ignition key.
3. Keep holding the buttons down for a few seconds until “Diag” pops up.
4. Release the two buttons.
5. Depress and hold down the Reset and the Select buttons again until a number appears on the display.
6. Use the Select button to scroll through the numbers until you find the number 61.
7. #61 is the “Error history,” and shows which error codes have appeared.
8. Slide to #62 with the Select button.
9. #62 is the “Erasing error history,” which lets you know the number of errors.
10. If this number is not zero, on #62, press the hand warmer button back to zero.
11. Shut the ignition off, wait a couple of seconds, then turn it on again.
12. If the malfunction causing the fault code is no longer present, the codes won’t be displayed any longer.

In a nutshell, the seven best ways to make your snowmobile quieter are as follows:

1. Pay attention to maintenance
2. Modify the exhaust system
3. Consider a new muffler
4. Avoid performance modifications
5. Install hood insulation foam
6. Wear earplugs
7. Invest in a quieter sled

If you want to find out more about these practices, you’ve come to the right place. We at PowerSportsGuide have gathered all the best tricks on how to make your snowmobile quieter!

The 7 Best Ways to Make Your Snowmobile Quieter

1. Pay attention to maintenance

There’s no question that the easiest way to keep your snowmobile quiet is if you pay attention to its maintenance.

Holes or cracks on the exhaust system or even an exhaust manifold leak can make your sled much louder. Exhaust malfunctions not only generate annoying noises, but they can result in engine issues due to the lower backpressure. Besides a broken exhaust system, engine malfunctions can also make your sled significantly louder.

But even if everything looks good on the outside, there may still be problems with the packaging inside the muffler.

Let’s move on and discuss how to make your snowmobile exhaust quieter!

2. Modify the Exhaust System

How to make your snowmobile exhaust quieter?

Over time, the muffler packing is prone to becoming loose or damaged, resulting in higher noise levels. The simplest and cheapest way to make a snowmobile’s exhaust quieter is to replace the muffler’s insulation material.

Also, if you’ve purchased your sled as a used vehicle and find that its muffler is too loud, you should cut into it and check what’s inside. Many owners remove the insulation material from their mufflers to get some extra horsepower, and maybe that’s what happened to your sled as well.

To repack your snowmobile muffler, you have to disassemble or cut the muffler open, add the new insulation material, then weld/reassemble the muffler. Best practice is to use the same type and amount of material as the OEM setup was originally.

Keep in mind that packing more material inside the muffler can restrict airflow. Although it may result in a much quieter exhaust, this mod can also rob some horsepower.

What’s more, too much back pressure may end in engine malfunctions, especially on a 2-stroke sled. So, be careful when you repack your snowmobile muffler, and make sure not to stuff too much material inside.

Surprisingly, some owners repack their snowmobile mufflers every year to keep their exhaust system as silent as possible.

Once you’ve removed the muffler, you should also check whether the baffle is in place. Snowmobile baffles can also loosen over time, causing loud noises.

It also makes sense to wrap the pipe with high-temp exhaust tape to make your snowmobile quieter.

3. Consider a New Muffler

Some sleds, especially vintage race-intended models, came with racing pipes without mufflers. As you might assume, these machines are extremely loud, so installing a muffler on them is always a great idea.

Even if your sled is equipped with a muffler, it may not be as quiet as it should be, as snowmobile mufflers tend to become louder over time.

That’s why you should first try replacing the insulation material inside it. If that doesn’t get the results you hoped for, you may want to consider investing in a new muffler.

One of your options is to purchase a new OEM muffler with the same part number. Besides factory units, you can also choose from a plethora of aftermarket snowmobile mufflers.

Although most of them are louder than their OEM counterparts, you can still find few “silent snowmobile mufflers” on the market that are specifically designed to reduce the noise levels of sleds.

Before you modify your exhaust system, don’t forget to check local laws, as these mods are not legal in certain states and provinces!

4. Avoid Performance Modifications

If you want to keep your snowmobile as quiet as possible, it’s recommended that you avoid any performance modifications.

Superchargers, turbochargers, performance air intakes, or virtually any engine performance mod will make your sled louder. Although these aftermarket parts are intended to boost the power of the sled, the extra horsepowers always result in louder noise emissions, not to mention lower reliability and durability!

5. Install Hood Insulation Foam

Another great way to make your sled quieter is to install insulation foam on the inside of the hood and side panels.

As a rule of thumb, newer sleds typically come with this foam installed, but a lot of owners remove it on the first day to shave a little weight off their sled. Factory foams are typically made of “open-cell” material, which is prone to accumulating water, oil, and dirt, which means some undesired extra weight.

Another common problem with these factory-installed foams is that they can easily fall off the panels.

That’s why many used sleds run without any foam inside their panels and hood. What’s more, a lot of vintage sleds were manufactured without these sound-dampening features.

Whatever the reason for your machine not featuring these foams, if you want to make it quieter, best practice is that you reinstall them.

You can choose from both OEM and aftermarket foam kits based on your needs and budget. If you go with an aftermarket kit, make sure it’s made of closed-cell foam to avoid absorption issues. Also, it has to be fuel and heat resistant, just like OEM foams.

You can glue the foams onto the panels with 3M or Ram-Tack spray adhesive.

6. Consider Earplugs

Okay, this trick won’t make your sled quieter, but it can help long rides be more comfortable.

Even if your sled is not extremely loud, your ears may start to resonate or even hurt after a few hours of riding, especially if you have sensitive ears. Besides the unpleasant headache and ear ringing, in the worst-case scenario, this can lead to hearing loss in the long run.

To avoid these issues, it’s recommended to wear earplugs on longer rides. You may be surprised how many riders use them!

Earplugs are very small, easy to use, and cost nothing, so it makes sense to keep a pair on you.

7. Invest in a Quieter Sled

If none of the above helps, your last chance is to invest in a quieter snowmobile. The noise emission is dependent on many factors like its engine type, performance, and features. Therefore, some sleds are generally much quieter than others.

The general rule is that the more performance the engine produces, the more noise it emits. Primarily turbocharged snowmobiles are known for their noisy engines. Due to their design, 4-stroke snowmobiles are quieter than 2-strokes.

Therefore, the quieter snowmobiles with regular internal-combustion engines are the non-turbocharged, 4-stroke models. But if you are looking for the quietest sleds on the planet, you should take a look at electric snowmobiles!

Takeaway

As a takeaway, we’ve compiled the most frequent questions on the topic.

How Can I Make My Snowmobile Quieter?

The seven best ways to make your sled quieter are as follows:

1. Pay attention to maintenance
2. Modify the exhaust system
3. Consider a new muffler
4. Avoid performance modifications
5. Install hood insulation foam
6. Wear earplugs
7. Invest in a quieter sled

Are 4-Stroke Snowmobiles Quieter?

Yes, thanks to their engine design, 4-stroke snowmobiles are quieter than their 2-stroke counterparts. What’s more, specific 4-stroke sleds feature their mufflers on the rear side of the sled, which also contributes to lower noise levels.

So, if you are in the market for a quiet trail snowmobile, you can’t go wrong with a 4-stroke sled. But when it comes to mountain riding, you can only select from the noisy 2-stroke machines!

Is There a Quiet Snowmobile? 

If you are looking for a very quiet snowmobile, then a innovative electric sled is for you. They not only run completely clean, but they are by far the quietest snowmobiles in the marketplace!

We at PowerSportsGuide have compiled eight vital tips on how to start a snowmobile the right way!

1. How do You Start a Snowmobile with an Electric Start?

If your sled features an electric start, you can start it in eight simple steps:

1. Make sure you’ve done the pre-ride checklist
2. Attach the key and turn it to ON position
3. Attach the tether cord
4. Make sure the fuel line is ON
5. Pull the choke lever out/operate the primer (if featured)
6. Turn the key to START position/press the START button
7. Warm up the engine and the track
8. Release the choke (if featured)

Many sleds come with a handlebar-mounted START button, while on others you have to turn the ignition key to start the engine.

Unfortunately, on some models like the Yamaha SideWinder, the key switch is in an unfortunate place, so you have to take your glove off to turn the key.

As you might assume, this is not convenient, especially on cold days! Because of this, some SideWinder owners install a push-button on their handlebars for easier starts.

In contrast, Ski-Doos utilize a unique key known as DESS (Digital Encoded Security System), which is specifically programmed to the sled’s computer. Once this key is attached to the sled, you can start its engine with the press of a button.

2. How do you Pull Start a Snowmobile?

Unlike their electric-start counterparts, starting a pull-start snowmobile requires a little bodywork. The steps for properly starting a pull-start sled are as follows:

1. Make sure you’ve done the pre-ride checklist
2. Attach the key and turn it to ON position
3. Attach the tether cord
4. Make sure the fuel line is ON
5. Pull the choke lever out/operate the primer (if featured)
6. Pull out the handle of the recoil starter until you feel resistance
7. Pull the cord firmly
8. If the engine doesn’t start, repeat the pull a few times
9. Warm up the engine and the track
10. Release the choke (if featured)

How Many Pulls Should It Take to Start a Snowmobile?

As a rule of thumb, a snowmobile should start with 1 to 4 pulls. If the engine is warm, the majority of sleds start on the first pull. However, with a cold engine, you can expect it to take 2-4 pulls.

The exact number of pulls depends on various factors like the engine size and features, the condition of the sled, the strength of the pulls, and the temperature.

Why Does Your Sled Take So Many Pulls to Start?

There can be many reasons why a snowmobile only starts after many pulls, but the most common are as follows:

• Cold weather
• The design of the sled
• Fuel line issues
• Engine/starter issues
• The sled has been sitting for a long time

It’s safe to say that the most common reason why it’s hard to pull-start a snowmobile is the low external temperature.

The cold weather causes the engine oil to thicken. And the thicker (colder) the oil is, the more difficult it is to turn the engine over. This is why it is so hard to pull-start a snowmobile in the cold, especially if it sat outside during the night!

Also, don’t forget that the engine’s design greatly affects how easily it can be started as well.  

Big bore snowmobiles are generally harder to start, especially the 3-cylinder models. The more cylinders you have to move, the harder it is to turn the crankshaft over.

But even within the same category, some snowmobiles are simply harder to pull-start due to their design and features. As an example, the size of the recoil puller can also affect the difficulty of starting. You might be surprised by the difference caused by a bigger pulley!

Besides its design, the condition of the sled is no less important. In a worst-case scenario, the engine has some serious problems or has even seized. Electric or fuel line issues can also cause starting issues, which results in a lot of pulling.

3. How do You Make a Pull Start Easier on a Snowmobile?

If you feel it’s hard to pull-start your sled, here are some tips to make it easier:

• Make sure that the starter works properly, and the pulley is aligned perfectly.
• Check the tension of the belt, if it’s too tight can also cause a difficult pull.
• Consider a larger starter pulley.
• Inspect the clutch and make sure that nothing touches it.
• Use the proper pulling technique.
• If none of these helps, you should inspect the engine.

In many cases, the cord is bound up somewhere, or the pulley of the starter is misaligned. If the cord doesn’t come down off the pulley at the optimal angle it causes harder pulling than usual.

It’s also recommended that you check the clutch as well. If something touches the clutch, or the belt is too tight this can also result in harder starts.

Another common trick is to replace the pulley with a bigger one.

Also, make sure that you use the proper staring technique. Always try to use your entire upper body and not just your arms. The best practice is to put one of your feet on the footrest and grab the handle with both of your hands.

Pull out the cord slowly until you feel resistance, then pull it suddenly while leaning backward. Using your body weight during the pull can make the start significantly easier, especially for those with shorter arms/weaker muscles.

If you feel that pull-starting your sled every time is exhausting, you should consider an electric start instead!

4. How do You Start a 2-Stroke Snowmobile?

Starting a 2-stroke snowmobile is not really different from a 4-stroke as long as it features a fuel-injected (EFI) engine. But if it has carburetors, you will have to use the choke/primer to start the sled properly. Why?

This is because if a 2-stroke snowmobile engine is cold, it needs a richer mixture to start. To make the mixture richer, these sleds are equipped with a primer or a choke, depending on the model.

Let’s drill into the details and see what they are exactly and how to use them!

What Does a Primer do on a Snowmobile?

Simply put, the primer on snowmobiles is a valve that pumps fuel into the carburetors. The inlet of the primer is attached to the fuel line, while its outlet is connected to the ports of the carburetors. You can typically find the primer lever on the dashboard.

To start the sled correctly, you have to check the manual as to how many times you should operate the primer. Every time you pull the primer lever, the system pumps a little extra fuel into the carbs, which results in a richer mixture.

How do You Start a Snowmobile with a Choke?

The choke on a snowmobile does the same job as the primer, but it works differently. In a nutshell, to make the mixture richer, the choke restricts the airflow into the carburetor.

If your sled utilizes a choke, its lever must be pulled out before you start the engine. You typically have to use the choke only if your engine is cold. Once the engine has warmed up, you can release the choke.

Just like the primer lever, the choke lever usually can be found on the dashboard.

If you can’t find the choke lever on your sled, you should carefully check your carbs. You can see some cables coming out from it that go to the dashboard. Some of them have to be connected to the choke lever!

5. How do You Start a Snowmobile with an Empty Battery?

If you want to start a sled with an empty battery, the best practice is to “emergency start” it by wrapping a rope around its clutch. Another well-known trick is to jump-start the sled with a car or another sled. While jump-starting works well on vintage snowmobiles, it’s typically not recommended on newer models.

Let’s face it, modern sleds are stuffed with electronics, and most of them feature a main computer to control these systems. If you jump-start these snowmobiles, you risk permanently damaging this computer, which can be very expensive to replace.

What’s more, jump-starting a snowmobile has many other risks, which are always clearly stated in the operator’s manual. Because of this, snowmobile manufacturers typically don’t recommend jump-starting. Instead, sleds should be started with an “emergency rope.”

Are you wondering how to do this? Keep reading!

6. How do You Start a Snowmobile Without a Pull Cord?

If the starter fails or the pull cord breaks on your sled, don’t worry, as you can still start it with a simple trick. All you need to do is wrap a small rope around the primary and simply use it as a pull cord. Manufacturers typically include this emergency starter rope in the tool kit.

If your tool kit doesn’t feature this addition, you can still use a piece of thin mountain climbing rope or a ratchet strap for this purpose.

When you start your sled with this emergency rope, be careful as you have to put the side panel back while the engine is running.

Here’s a great tutorial on how to start a snowmobile without a pull cord:

7. How to Start a Flooded Snowmobile

A flooded snowmobile engine is always a headache. If you’ve also flooded your sled, just engage the parking brake, hold the throttle wide open and pull the cord until the engine starts. If this trick doesn’t help, you can still try to start a flooded snowmobile by following these simple steps:

• Pull the plugs out and dry them off (ONLY do this step if the engine and the plugs have cooled down!)
• Turn off the shut-off switch (and make sure you have no sparks)
• Hold the throttle wide open
• Pull the sled over at least 15-20 times – you will notice some gas spray coming out of the cylinders if you’ve removed the plugs
• Replace the spark plugs
• Engage the parking brake
• Hold the throttle wide open and start the engine

Again, be sure to only remove the spark plugs when the engine is cooled down.

Here’s a great video on how to start a flooded snowmobile:

8. How do You Start Snowmobile After it’s Been Sitting?

If your snowmobile has been sitting for an extended period, you may want to take the following steps before the first start:

1. Take the plugs out and check the cylinders visually
2. Do a compression test on each cylinder
3. Put a little premix into the cylinders and turn the primary slowly by hand – the crank and the pistons have to move smoothly (Anything scraping, grinding, or catching is a bad sign!)
4. Inspect and clean/adjust the clutch if needed
5. Replace all filters and fuel hoses (inside the tank as well!)
6. Drain the old fuel/oil and replace them with fresh ones
7. Pull out the carburetors and clean or even rebuild them if needed
8. Clean and inspect the entire machine carefully
9. Watch for signs of mice and critters (exhaust, airbox, under the side panels, etc.)

Takeaways – Related Questions

Can You Start a Snowmobile Without a Clutch?

The general rule is that running a snowmobile without a clutch is definitely not recommended. The primary clutch on the crankshaft acts like a harmonic balancer that can smooth out the motion of the shaft. The engine can easily vibrate or over-rev without the clutch, even just by adding a little throttle. Eventually, it can lead to permanent clutch or engine damages.

In the worst-case scenario, the engine will over-rev and wouldn’t slow down even if you release the throttle. In such cases, you can only shut down the engine by pulling off the fuel line.

Can You Start a Snowmobile Without a Belt?

Because of the reasons mentioned above, it’s not recommended that you start a snowmobile without a belt. Without the drag of the belt and the secondary, the engine can easily over-rev, which may end in permanent damage. What’s more, the clutch sheaves can slam together and break, throwing pieces of metal everywhere.

Instead of removing the belt, the best practice is to jack up the rear of the sled. In this way, you can start the sled and rev up the engine with its belt.

Can You Jump Start a Snowmobile?

While vintage snowmobiles can be jump-started relatively risk-free, this is not recommended on newer machines. Doing it wrong can damage the computer. This is why manufacturers don’t recommend jump-starting snowmobiles unless it’s unavoidable.

Instead, the best practice is to use the “emergency rope” to pull-start it using the primary clutch.

How do You Start a Snowmobile When the Recoil Breaks?

If the recoil brakes on a snowmobile, you can still start it with the primary clutch. Just wrap the emergency rope around the primary and pull the cord.

In most cases, this emergency rope is included in the repair kit, but you can also use a thinner mountain climbing rope or a racket strap.

Can you use a drill to start a snowmobile?

No, using a drill to start a snowmobile is definitely not recommended. “Drill starting” may work on small engines but not on snowmobiles.

These high-performance vehicles utilize powerful engines, which are only started by their own electric or pull start systems.

1. Use a seat pad.
2. Install a seat wedge.
3. Raise the original seat with a bracket.
4. Install a snowmobile seat riser kit.
5. Invest in an OEM comfort seat.
6. Consider an aftermarket seat.
7. Borrow a seat from another powersport vehicle.
8. Build your own DIY seat from scratch.

If you want to find out more about these tricks, this post is for you.

Without further ado, let’s drill into the details!

8 Easiest Ways to Raise a Snowmobile Seat

1. Use a Seat Pad

There’s no question that the easiest way to raise a snowmobile seat is to install a seat pad. These pads are actually throwable seat cushions that are commonly used for raising and softening motorcycle seats.

These pads are easy to install as they can be simply strapped on top of the seat. They come in many shapes and sizes and are filled with air, water, gel, or foam depending on the model.

Since special snowmobile seat pads are quite rare on the market, you should consider investing in a motorcycle seat pad.

They are cheap and quick to install, which is why they are so popular among motorcycle riders.

On the other hand, keep in mind that these pads are prone to sliding on the saddle, so they probably won’t stay in place for the long run. Gel is prone to becoming stiff in the cold and water-filled pads are also not recommended for obvious reasons.

However, foam pads can work as a temporary solution. Just make sure you attach it as tightly as possible.

Are you looking for something permanent and more stylish? Keep reading!

2. Snowmobile Seat Wedge

When it comes to raising a snowmobile seat, aftermarket seat wedges are often overlooked. These products are large plastic wedges that can be installed under stock seats.

They are designed to primarily raise the rear of the seat, but you can notice a slight change on the front as well.

The main idea behind a snowmobile seat wedge is to adjust the angle of the seat, which can give you a more natural riding position. It can also result in less fatigue on longer rides.

As an addition, many of them offer a little storage below the seat.

Drawbacks?

First, these wedges are often model-specific, so they may not be available for your sled.

What’s more, some riders find this improved seat angle uncomfortable. This is because the steeper seat causes you to keep sliding forward towards the tank the whole time.

3. DIY Snowmobile Seat Riser

DIY snowmobile seat risers work in the same way as aftermarket wedges, but they are often flat or just feature a slight slope to the front.

If you want to raise the seat on your sled, you can build a homemade snowmobile seat riser from plastic, wood, or even metal.

The easiest way is to simply install a thicker UMHW plastic board under the seat. But if you are looking for something higher, you can even weld on a complete frame from metal or wood.

Thanks to their simplicity, these custom risers cost virtually nothing. If you like building this could be a great weekend project for you!

The other main advantage of these DIY snowmobile seat risers is that they work with the original seat. You don’t have to reupholster or modify your stock seat, only install the frame under it.

On the other hand, keep in mind these risers typically work well on vintage sleds in which the seat is directly bolted onto the tunnel.

Newer models typically feature a more complex body, so installing a homemade seat riser would be harder to accomplish.

And let’s face it, a wooden bracket like this would look really weird on a brand new sled!

4. Snowmobile Seat Riser Kit

One of the best ways to raise a snowmobile seat is to invest in a Snowmobile Seat Riser Kit.

Simply put, these kits typically contain a piece of extra foam and a new seat cover.

Installing the kit is very easy. You have to take the seat cover off, insert the additional foam onto the top of the seat, and as the final step install the new seat cover.

As a result, you can expect a nice hump on top of your seat, which offers a higher seating position.

Some kits contain the complete foam, meaning that you have to replace the entire foam on the seat.

The best snowmobile seat riser kits and covers are made by PowerMadd, Kimpex, and SaddleMen.

These kits are quite popular, but also have their own cons.

First, they can raise the seat on your sled about 2-3 inches depending on the design of the foam addition. Besides, they are definitely not cheap and often sled specific.

Therefore, if you are looking for a customized seat riser, you should consider rebuilding your seat based on your needs. All you need to do is to carve out the designed shape from a piece of foam and stick it onto the original foam.

Finally, you will need a new seat cover as the original won’t likely fit on your new saddle.

The main advantage of this solution is that you can raise the seat as high as you want!

5. OEM Snowmobile Comfort Seats

If you are looking for something really stylish and comfortable, you should take a look at the OEM comfort seats.

These saddles are designed for your sled, which ensures a perfect fit.

They are typically bulkier than their stock counterparts, so besides the extra comfort they may offer a slightly higher seating position.

What’s more, some of these saddles are heated and/or offer space for a passenger.

6. Aftermarket Snowmobile Seats

But if you are looking for something really stylish and comfortable, then aftermarket snowmobile seats are for you.

They are well-padded, extremely comfortable, and come in many sizes and shapes. The hidden advantage of these seats is that you can typically store a bag under them.

These seats are very expensive, but many riders claim that they worth the money!

Some of the most well-known aftermarket snowmobile seat manufacturers are Skinz, Boss, and Kimpex.

7. Other Seat Replacement Ideas

If you find OEM or aftermarket seats too expensive, or they just don’t fit on your sled, don’t worry.

You still have many other options!

It may seem like a crazy idea, but some owners replace their seats with a jet ski or motorcycle seat. Why not?

The seats of powersport vehicles are designed for the same purpose, so they can be interchangeable within certain limits.

What’s more, if you can’t find a suitable seat for your sled, you can even use the stock seat of a newer sled.

You may want to check eBay or Craigslist for used seats, as many owners part out their sleds.

8. DIY Snowmobile Seat

Last but not least, don’t forget that you can even build a custom seat from scratch. It makes sense if your existing seat is damaged or in just really bad condition.

If you have the required materials, it may cost you nothing (except your time of course).

However, you will definitely need some skills and tools as well.

If you want to dive into the details, here’s a great video on how to build a DIY snowmobile seat:

Advantages of Raising a Snowmobile Seat

If you are a tall rider, the benefits of raising your seat are clear. But there are many lesser-known advantages of raising the seat on your sled, which are as follows:

• It provides better visibility.
• You can get a small extra storage space under the seat (depending on the design of the new seat).
• The new saddle can give your sled a custom look, especially with a new cover.
• You can stand up easier from the saddle if you want to absorb the bumps.
• A higher seat offers a more natural riding position.
• You can expect less fatigue in your back and knees.
• If you raise the handlebar, raising the seat on your sled is a must!

Conclusion

A low seating position on a snowmobile can be an issue especially if you are a tall rider. This is a common problem on vintage sleds, which typically feature very low seats.

And riding in an uncomfortable position is never a good idea as it can lead to knee and back pain!

This is where aftermarket modifications come into play.

There are many great ideas on how to increase the seat height on a snowmobile, but the most popular ones are arguably as follows:

1. Seat pads
2. Seat wedges
3. DIY snowmobile seat risers (frame/board under the seat)
4. Snowmobile seat riser cushions
5. OEM comfort seats
6. Aftermarket seats
7. Replace the seat with a motorcycle or jet ski seat
8. DIY custom snowmobile seats

And as a final word, if you find your seat too low, your last option is to invest in a bigger sled.

However, this is arguably the most expensive way to get a higher seating position!

How do You Clean a Snowmobile Carburetor?

Remove the Carburetor

For a thorough cleaning, you have to first remove the carbs from the sled. To do this, you must remove the airbox, which is often the hardest part of the process!

Then, unclamp the carb and pull it out of the intake boots.

If your sled features more than one carb, removing and cleaning them all will be more time-consuming of course. But it’s always worth the effort as a clogged carb can sometimes result in a seized engine!

Remove the Cables/Fuel Lines

To remove the carb, you also have to pull off the fuel lines. Depending on the design of the carb, you can expect 2-3 fuel lines. Next, remove the choke and throttle cables. It’s very important that you remember where everything goes!

Best practice is to leave the top lock nut untouched to keep the original settings. If you don’t want to deal with readjusting the cables, it’s recommended that you not change the location of this nut.

Remove Internal Components

Let’s move on and start disassembling the carb.

As the first step, you have to completely remove the float bowl. If it’s a Mikuni carb, the bowl probably has a little corner screw.

Removing this screw, as well as the big center nut allows you to remove the float bowl. Next, you can start disassembling the internal components of the carb. Beware that spraying these parts down with carb cleaner spray will NOT be enough to get them thoroughly clean!

For precise cleaning, you may want to take out the jets. Don’t worry, as they can be easily removed with a standard screwdriver.

There are two jets in a snowmobile carb. The pilot jet, which can be found in a small tube on the main body. The other jet is known as the main jet and is located in the center of the carb. In some carbs, you may find a washer underneath the main jet.

As the last step, you have to remove the seat assembly as well as the needle. Disassemble these parts, so you can carefully inspect them.

Disassemble the External Parts

Let’s move on to the external parts of the carb, as you should remove them as well.

First, remove the fuel screw, but before you do, it’s recommended that you check the settings. In order to do this, just screw it in tightly. While doing this, you must count the turns of the screw. This will ensure the settings remain the same when you re-install it. After this, remove the screw from the body.

Next, remove the top cover plate and the jet needle. Check the needle carefully as these are prone to bending. Also, the needle jet hole needs to be opened to properly clean it.

Keep in mind that you don’t have to remove the flat side for cleaning.

Clean the Components – How do You Clean a Snowmobile Carburetor?

To clean a snowmobile carburetor, you will need a toothbrush, compressed air and liquid/spray carb cleaner. Many owners say that the best snowmobile carb cleaners are Gunk and Gumout sprays, but Berryman is also a popular brand.

Carb cleaners typically come as a spray or in small cans as liquid. Many owners prefer to spray down the parts with cleaner, and then use a toothbrush to clean them.

Another solution is to dip the parts in the cleaner. For your convenience, if a carb cleaner comes in a can it usually comes with a small drip basket as well. For best results, let the parts soak overnight in the cleaner.

Beyond dipping the parts, make sure to carefully clean them with a toothbrush. Another great trick for cleaning a snowmobile carburetor is to use compressed air.

You can simply hold the jets against the blower to clean it with air. You also have to soak the ports and clean those with compressed air as well. Check the outside of the ports while doing this and you should see a clean mist coming out!

Reassemble the Carb

As you can see, carburetors are made up of many small parts. The key is to not lose or forget to re-install any of them. Moreover, you have to remember where everything goes.

If you are not sure how to put it all back together, don’t hesitate to check the sled’s service manual. Additionally, if you are lucky, you can also find your carb’s service manual online.

Before starting to reassemble the parts, make sure that they are completely clean and in good condition.

If you notice that the jets are corroded, it’s recommended that you soak them overnight. If they are still in bad condition, it makes sense to replace them.

These small internal parts are really inexpensive as they cost only a couple of dollars per carb. The needle and the seat are also not very expensive. But replacing every internal part is more like a carb rebuild than a cleaning!

When it comes to the reassembly of a snowmobile carb, start by installing the pilot and the jets in the body.

Next, the main body seal has to be installed, and the face place must be bolted down. Then, insert the needle with the washer and the e-clip.

As the final steps, the top cover plate, the bowl, and the nuts have to be installed.

Reinstalling and Adjusting the Carb

Once you’ve reassembled the carbs, put them back in place. Reconnect the throttle and choke cables, as well as the fuel lines. Finally, reinstall the airbox.

If you left the top lock nuts untouched and screwed the fuel screws into the same position, hopefully there has been no change in the settings of the carbs.

If there has been, you will have to adjust the carbs. For proper carburetor settings don’t hesitate to check the service manual. If it is not available, be prepared for some back and forth until you set and sync the carbs perfectly.

Although the majority of snowmobile carbs are very similar, there can always be differences between the various brands. Let’s move on and check how to clean a carburetor on a variety of sleds!

Snowmobile Carburetor Cleaning by Brand

How do you clean a Ski-Doo carburetor?

How do you clean the carburetor on an Arctic Cat snowmobile?

How do you clean the carburetor on a Polaris snowmobile?

Can You Clean a Snowmobile Carburetor Without Removing It?

Although if may be possible to clean a snowmobile carburetor without removing it (to a certain extent), it’s not recommended at all. Why? First, a thorough cleaning always requires removing and disassembling the entire carb, which is not possible without removing it. On the other hand, if you try to clean the carbs while in place, you risk that the gum clogging the carb will get into the cylinders.

As it may end in a seized engine and a top end rebuild, cleaning the carburetors without removal is simply not worth the risk.

Will Sea Foam Clean Snowmobile Carbs?

Yes, Sea Foam can also be used to clean snowmobile carbs, but keep in mind that it won’t replace a complete cleaning procedure. Sea Foam works well as long as the fuel can flow through the passages. If your carbs are completely clogged, there is no alternative to removing the carbs and carefully cleaning them.

How Often Should You Clean Your Snowmobile’s Carb?

As a rule of thumb, you should clean your snowmobile’s carb at least once a year. Best practice is to do it before the season, as part of yearly maintenance. If you have starting issues, or your sled regularly bogs down, these are clues that you should inspect and clean the carbs.

Keep in mind that the majority of starting problems are caused by clogged carbs. As cleaning them doesn’t take too long, it makes sense to perform this simple maintenance task every year.

What’s more, as we discussed, carburetor malfunctions can even lead to a seized engine. Therefore, keeping your carbs clean is like having additional insurance on your sled!

If a sled has been sitting for years, its carbs have to be removed and cleaned, besides many other parts of course.

Conclusion

Carburetors are key parts of every snowmobile engine. It mixes air with the gas and feeds the engine with this mixture.

Unfortunately, carburetors are prone to getting dirty over time. That’s why it is recommended that you clean them at least once in every season, or if your sled has starting issues or regularly bogs down.

How do you clean a snowmobile carburetor? Simply put, you have to remove and disassemble it, then clean it with carb cleaner spray, a toothbrush, and compressed air.

If you notice that any parts are corroded or damaged, you may want to replace them. Carburetor internal parts are very cheap, so it makes sense to replace them to avoid future problems.

As a final word, don’t forget to carefully read your sled’s service manual before doing any maintenance on it!

How Can I Make My Snowmobile Go Faster?

How can I make my snowmobile go faster? – This question is commonly asked by many performance-minded owners.

It’s safe to say that the cheapest way to make a snowmobile go faster is to make sure it’s clean from any buildup of snow and that its systems are working properly. Therefore, if you want to get the most out of your sled it’s recommended that you carefully inspect and adjust/fix its key components.

Are you wondering which parts require extra attention? Keep reading!

Carbs/EFI

If you want to make your snowmobile go faster, the very first step is to clean its carburetors. If you notice that its internals are not in a good shape, best practice is to rebuild them.

After the cleaning/rebuilding, you also have to properly set the carbs. This means the carbs should be perfectly tuned and jetted.

If your sled features a fuel injection system (EFI), make sure that it’s correctly mapped to get the best available fuel/air ratio.

Clutching

It’s also good to know that an improper clutch setting or a buildup on the sheaves can often lead to decreased performance.

That’s why you have to inspect and clean the clutches, or even rebuild them if necessary. This is to make sure they are working smoothly!

If not, adjust the springs and weights to get a steady full-throttle RPM. Beware that properly setting the clutch may require many adjustments and test rides!

Besides the clutches you may also want to check the drive belt. Clean or replace it if needed, and make sure that its tension is adequate.

Final Drive Gearing (Chaincase)

When it comes to making a sled go faster, the final drive gears are often overlooked.

However, the sprockets in the chaincase can be replaced, which can lead to a higher top speed/better acceleration, depending on the size of the new gears.

This is because these gears do the same job as the gears on a bicycle. Simply put, different sprocket sizes always mean different performances. Don’t forget that if you change these gears you have to adjust the clutches as well.

Track, Skis, and Suspension

You may want to keep your eyes on the track. Check its tension and alignment, as a too tight or misaligned track can reduce the top speed and can lead to severe track damage.

Also, make sure that the sliders (hyfax) are in perfect condition, and don’t overlook the bearings of the idler wheels. Replacing the wheels with a “big wheel kit” can also help reduce the drag and the resistance of the track.

Additionally, it’s a lesser-known fact that you can make a snowmobile go faster by changing the size of the track drivers!

For the best performance available, don’t forget to align the skis and sharpen the carbides. If your sled has darting issues, you may want to eliminate that as well.

And finally, it’s recommended that you check the suspensions. You can adjust the weight on the skis by the strap limiter.

Other Important Factors to Consider

It’s also wise to shave some weight off your sled. Sledders are prone to carry a lot of gear on their sled, and let’s face it, some of it is probably unnecessary.

Increased weight always means a worse power-to-weight ratio, which results in lower performance.

It’s also important to use good quality oil and fresh fuel. This not only makes your engine last longer, but also ensures the highest performance.

7 Best Snowmobile Modifications

You’ve got all of the above right, but still want to make your sled faster?

This is when performance modifications come in handy.

Adding extra power to the engine can significantly boost engine performance. But on the other hand, you have to be able to handle this increased power, so mods/adjustments on the track and the steering system are usually unavoidable.

Are you wondering what the best performance modifications are on a snowmobile? Here are some common mods to make your sled go faster:

• Big bore kits
• Turbocharger/supercharger
• Exhaust system
• Vents
• Tracks/studs
• Skis/carbides
• Running board

Let’s take a closer look at each!

The Best Snowmobile Performance Modifications

Big Bore Kit

The safest and most effective way to increase the performance of your engine is to add displacement.

This means installing a “big bore kit” on the engine or even replacing it with a bigger one. As an engine replacement is a pretty costly modification, using a big bore kit is much more common.

What is a snowmobile big bore kit? Simply put, a big bore kit means new “bolt-on” cylinders with bigger displacement, or sometimes boring out the original cylinders. The kit typically contains new pistons, rings, gaskets, and many other components that you need for this upgrade.

If you install a big bore kit you will also have to adjust the carburetor/fuel injection system. This way you can be sure that every system will work together.

Price?

Unfortunately, the price of snowmobile big bore kits ranges from $1,000 up to several thousand dollars. And don’t forget that this is just the cost of the parts and doesn’t include the labor!

Turbochargers and Superchargers

Another common way to increase a snowmobile’s performance is to install a supercharger or turbocharger.

Both of these units do the same job, they force compressed air into the engine, which results in higher performance. The main difference between them is that the turbo is driven by exhaust gases, while the supercharger is connected directly to the crankshaft.

This makes the supercharger more responsive, which means it doesn’t have any “turbo lag.”

As a rule of thumb, superchargers are much easier to install and adjust while turbochargers offer much better performance.

The biggest cons against these units are the increased fuel consumption and the decreased reliability.

Exhaust

A freer-flowing snowmobile exhaust can lead to higher performance as well. Thus, this is a popular aftermarket performance part! Drawback?

The main con of these exhaust systems is probably their significantly higher level of sound. That’s why exhaust modifications on snowmobiles are prohibited in many areas!

But if you are looking for a “quiet” aftermarket exhaust, the good news is that many newer models produce very moderate noise while still increasing engine performance. However, to stay legal and not disturb others always check and obey the applicable laws in your area!

When it comes to aftermarket snowmobile exhaust prices, you can see price tags from $250 up to $1,000+.

Vent Kits

A high temperature under the hood not only robs power from the engine but can also shorten the life of the clutches and the belt.

You can keep this key area cooler by simply installing an aftermarket vent kit.

These parts typically are mounted on the front of the hood, and the sides of the side panels. They make the body of the sled more “open,” and this way feed the engine and the clutches with cool air.

An additional benefit of these vents is that they make your sled more personal.

Here is a good tutorial on how to install aftermarket snowmobile vents:

Tracks/Studs

Although stock snowmobile tracks usually do a very good job, in some cases it makes sense to replace the track. If you are looking for more traction or flotation, a new track with different dimensions could be a solution.

If you are considering replacing your track, you may find our track selection guide useful.

Another common modification of snowmobile tracks is studding. The small metal studs do a really good job on ice and hard-packed snow, as they ensure much better traction.

Skis/Carbides

To handle the increased performance, you will probably need longer carbides. Sharp and correctly sized carbides are a must if you ride on the trails.

However, carbides can also come in handy in powder as well, as you never know when you may hit an icy spot under the snow!

If you are an off-trail rider looking for better flotation, you should take a look at aftermarket skis. They come in many sizes but are lighter compared to their stock counterparts.

Thus, contrary to popular belief, aftermarket snowmobile skis are not just for a customized look!

If you are a hardcore rider, you will probably have to modify the suspensions as well for perfect handling.

Running Boards

When it comes to modifying a snowmobile, it’s safe to say that replacing the running boards is one of the most common mods, especially on off-trail sleds.

This is because on the aftermarket running boards you can expect much less snow buildup. This not only means less weight but more safety as well. Why?

Simply put, snow under the feet always means less traction, which may result in handling issues and ultimately dangerous situations!

What’s more, nice aftermarket running boards can give a custom look to your sled.

But be careful, and mount them properly to the tunnel, as improper installation can lead to loose boards!

Conclusion

If you want to make your snowmobile go faster first make sure that all of the key components (engine, carbs, clutches, track) work properly. If not, clean/adjust/ or even fix them if necessary!

If you are still not happy with the available top speed, your other option is to modify your sled. This process typically means installing aftermarket parts like big bore kits, turbochargers/superchargers, aftermarket exhaust systems, vents, and so on.

You can also consider replacing the entire engine, but let’s face it, this is not a Sunday project!

For better handling, you may want to install longer carbides/aftermarket skis, studs, custom running boards, or suspension upgrades.

For your convenience, all these parts are usually available in kits as well. These kits are typically labeled “stage 1-5” depending on the number/quality of the parts they contain.

The rule of thumb is the higher the number, the more parts and higher performance (and price) you can expect.

Keep in mind that if you start to modify your sled, it can easily become a never-ending story, as you may need new parts again and again. What’s more, it usually ends in many issues as these modifications can foul the sensors and decrease the lifespan of the engine as well.

That’s why many experts say that if you want a faster snowmobile, the easiest, and sometimes the cheapest way to go is to purchase another, more powerful sled.

Even if the prices of new snowmobiles may be shocking at first glance, it’s definitely worth doing the math upfront.

You can easily spend thousands of dollars for modifications, and the result may still be a sled that lags behind the top speed of many stock performance sleds.

Consequently, in many cases, it makes more sense to put this money into another snowmobile. You can get a much faster sled this way, without any hassle!
