How To Snorkel An ATV, Snorkel Kit Or Make Yourself – AtvHelper

If you plan on driving your ATV through deep water or mud, getting a snorkel on your machine is something you might want to consider. A snorkel will help keep water out of your engine, so you can get through some pretty nasty areas on the trail without damaging your ATV.

If you get yourself into some deep mud or water for too long, your engine could stall. Your air intake could take on water causing major problems and costly repairs. I’ve done this before, as you can see in the picture, and that quad didn’t have a snorkel on it.

Luckily I was able to shut the engine off before major damage was done, but still it ruined the day of riding for us. I need to be towed out of the muddy water, then we had to open the air box and wait for everything to dry out before we were able to get the quad running again. If that ATV had a snorkel, there would have been no problems.

What Is An ATV Snorkel?

Snorkeling your ATV is when you install a system onto your engine that will allow air to get where it needs to even in deeper water or mud. You will most likely see risers or stacks sticking up from the quad to capture or release air safely above the water line.

After you install a snorkel on your machine, the only part you need to worry about keeping above water is the opening of those stacks.

Snorkeling your ATV is most useful for getting though deep water or mud. It will keep water out of the most important parts of your engine that are only supposed to subject to air. Feeding clean air safely to your engine to keep you riding through wet environments.

What Needs To Be Snorkeled?

The main components you will need to snorkel are the air box, your clutch belt intake, and clutch belt exhaust. The clutch belt intake and exhaust will both need their own snorkel. If you try to connect them, the intake will be getting the heat from the exhaust and will overheat and wear out your clutch belt.

You may want to snorkel your exhaust ports as well. If you’re giving the engine enough gas going through the water, that pressure should prevent any water from entering the exhaust. But if by chance water does enter through your exhaust it could cause major problems. This will most likely happen if plan to sit idling in the water.

It’s also a good idea to water proof your electrical connections. I’ve heard of people snorkeling their electrical box, but that seems like overkill. The point is to just prevent water from getting to the electrical parts of the engine.

Other areas to snorkel might include thing like your crackcase breather tube or differential vents and carb vents. If you’ll be hitting the occasional mud pit or stream crossing, the air box, clutch belt, and electrical stuff need to be taken care of as well as the carb breather if your engine has a carburetor.

ATV Snorkel Kits

There are some pretty good kits available on the market for most machines. The snorkel kits will vary from quad to quad because they are all set up a bit differently. A snorkel kit will be more expensive than making your own, but will come with everything you need and make for an easier quicker install. Plus the kits might even come with some kind of warranty.

You can use this link to find a Good ATV Snorkel Kit on Amazon. Just be sure to get the right one for your machine. They kits will vary a bit and the parts are custom made for each different engine.

I don’t need to go over installation here because the snorkel kits come with instructions that are really easy to follow along with. You will need some basic hand tools to get the snorkel kit installed and you’ll be all set.

Make Your Own ATV Snorkel System

Making your ATV snorkel can be fun and won’t cost you too much money either. I’ll admit, a lot times it won’t look as nice as the professional snorkel kits you can buy, but if you do it right it will work all the same.

The cheapest thing to use is just some good old pvc pipe. You can find pvc pipe at any home repair store like Home Depot or Lowes. It’s best to know the path you’re going to take first and plan out how many bends, how much pipe, and how many 90 degree connectors you will need.

First, locate your air box and see what you’re going to need to snorkel it. A lot of quads already come with a factory snorkel, they just don’t go very far. In this case you can hook some pvc right to that factory snorkel and just extend it up as high you’d like.

I’ve seen some people use pool hose to navigate around the engine easier than you could with pvc pipe. It looks a little raggedy with the duck tape and all in this picture, but i’m sure if you secure it right and use some better connectors you can get a decent looking snorkel system going.

If you have a carburetor on your engine, it’s pretty easy to just extend the carb breather tube that’s already existing on the quad. You can find little tube connectors at most auto parts stores like Napa or Autozone. The just get some tubing and extend the carb tube up to a safe area on the machine.

Do the same thing for the front and rear differential breather. These lines are usually already ran pretty high up onto the quad up near the handle bars. But if you want them to be even further up out of the water it won’t hurt to extend them.

Disclaimer

Snorkel kits or snorkeling your ATV may be illegal in some states. I think for the most part it’s allowed on private property either way. But some states don’t allow snorkeled machines on public land.

Check your local laws before riding any modified machines on public land.

Do-it-yourself ATV muffler tuning.

Varieties. Methods.

ATV muffler tuning can be conditionally divided into four types of tasks to be solved:

  • Exhaust thermal insulation;
  • Exhaust noise reduction;
  • Increased engine power by installing a straight-through muffler;
  • Installation of a snorkel on the exhaust pipe of an ATV (for swimmers).

As you can see, each of the above types of muffler tuning solves its own, specific task, but we will try to acquaint you with all four types of muffler tuning as briefly and as easily as possible and give you, as they say, food for thought. nine0003

You may be interested in the article - "Cleaning the muffler of an ATV with your own hands."

ATV mufflers.

This type of muffler is designed to increase engine thrust, lighten the stock design (especially important for sports tuning), and, in addition, these mufflers have a beautiful acoustic effect.

The increase in power is due to the fact that all unnecessary elements that can slow down the flow of exhaust gases are removed from the design of the muffler, roughly speaking, the exhaust in this case goes without obstacles, directly. There are a great many models of direct-flow mufflers for ATVs on sale, but their cost is very high, and therefore craftsmen make direct-flows with their own hands. nine0003

We bring to your attention the simplest scheme of a straight-through muffler.

As well as the finished silencer in the section.

And you can appreciate the pleasant and daring sound of a straight-through muffler by watching this video.

ATV Exhaust Thermal Insulation.

Why is it necessary to insulate the muffler pipes and reduce their heat transfer? Most often, this type of tuning is used on ATVs, the exhaust system of which is very close to the gas tank and, with the active operation of the ATV, brings a lot of trouble to the owner. nine0003

There is also an opinion that reducing the heat transfer of the muffler pipes allows you to keep the exhaust gas temperature high, which, in turn, increases the exhaust gas flow rate and has a positive effect on engine health.

A special muffler thermal tape is used to insulate the pipes. There is a tape with a width of 2.5 and 5 cm, for an ATV, a width of 2.5 cm will be optimal. nine0003

When reassembling the exhaust system, use heat resistant sealant to seal the joints.

Silencer for ATV.

This type of muffler tuning is especially relevant for hunters, but can also be indispensable for people riding an ATV with a loud exhaust in densely populated areas. The disadvantages include a decrease in engine power when using additional mufflers, although manufacturers claim that this does not happen. nine0003

Factory models of additional mufflers (for example, KOLPIN) are very easy to mount on an ATV and also easy to dismantle if necessary, but again everything comes down to money, and ATVs make an additional jar with their own hands and connect it to the main muffler using a small pipe and clamps .

You can listen to the sound of the exhaust with an additional muffler in the video below.

ATV exhaust snorkel. nine0020

This snorkel is made solely to avoid water entering the engine through the exhaust pipe and to easily overcome deep fords.

It is very easy to make a nozzle: as a donor, you can use the muffler pipes of a VAZ car, choosing the most suitable length in the store, welding a snorkel of the shape and length you need on the spot, and you can fix the structure with clamps.

If overcoming fords is not a frequent occurrence for you, it is more expedient to use a stainless corrugated pipe (sold in hardware or plumbing stores) and attach it with clamps for the duration of the “water procedures”. nine0003

Well, in the end, we offer you a photo of frankly brutal exhaust tuning, as you can see, sometimes everything is limited only by our imagination. Good luck on the road and stay with us.

ATV muffler gets hot - an overview of causes and solutions

Think about how often you service your ATV? But this is an important component of the "health" of the all-terrain vehicle, on which the operation of all transport systems depends. And even if you decide to buy a new ATV, be prepared for the fact that sometimes you will have to face problems. For example, many riders complain that the ATV exhaust pipe gets hot. But this is a “bell” that some systems of the device do not work correctly. So let's figure out what to do if the muffler of the ATV is hot. nine0003

Why does an ATV muffler heat up?

In fact, there are not so many reasons for the strong heating of the exhaust system. Most often, this situation occurs due to:

  • Too lean or rich fuel mixture.
  • Clogged air filter.
  • Damage to the spark arrestor.
  • Late ignition.

There are not so many reasons why the exhaust pipe gets hot on an ATV. And almost all of these problems can be eliminated even by a novice rider. nine0003

Incorrectly prepared fuel mixture

Even novice drivers know that the fuel mixture is prepared from gasoline and air. But at the same time, the proportions of the components play an important role. For example, if there is more air than gasoline, then the mixture will turn out to be too poor. And here the problems begin. A lean composition leads to a number of problems:

  • Loss of traction on the ATV.
  • A noticeable drop in quadric power.
  • Stopping the power unit. nine0006
  • Incorrect engine operation.

A lean mixture is also one of the reasons why the muffler gets hot on an ATV. The fact is that the remaining fuel gets into the pipe, which explodes in it. This leads not only to an increase in the temperature of the exhaust system, but also to serious damage.

How do you know if the mixture is lean?

If the ATV exhaust pipe gets very hot, first make sure the fuel mix is ​​properly prepared. You can diagnose the problem by several key symptoms:

  • ATV engine has started to malfunction.
  • Quadric power and traction decreased.
  • The device began to "sneeze".
  • The insulator on the spark plug has a pale tint.

A simple carburetor adjustment will solve the problem. You can learn more about the procedure for cleaning and tuning the fuel system in our article.

Spark arrester problems

Another reason why the muffler on an ATV gets hot is a melted spark arrester. This is a special mesh that is designed to dampen vibrations and noise. However, sometimes this component can melt or simply clog. Because of this, the exhaust gases will not be able to exit the pipe, which leads to an increase in the temperature of the pipe. nine0003

To check the spark arrester, unscrew the 3 bolts at the end of the exhaust pipe and carefully pull out the "innards" of the system. If the mesh is just clogged, it can be blown out. But the melted component should be replaced or completely abandoned.

Spark arrester problems are usually caused by an incorrectly tuned carburetor, rich or lean composition. If all quadric systems work correctly, the grid is cleaned every 10-12 thousand km.
