Can I Ride a Dirt Bike Without an Air Filter?


One of the most annoying things, and I’m sure it is annoying to you too, is cleaning your dirt bike’s air filter. While cleaning the air filter should happen after almost every ride, it is very annoying.

And because the air filter is so annoying, a lot of people ask me if they can ride a dirt bike without one. The short answer is no, you can’t ride without an air filter. If you do so, you will put loads of dirt, dust, debris, and bacteria into your engine because your dirt bike would not prevent some layer of dirt that you encounter during riding. This will cause your engine to heat and create very big problems that can cost you a few hundred dollars at best while the worst case is, your engine will just be destroyed.

You have to understand that your air filter may be a cheap and inexpensive part, but it has a huge meaning not only for your engine but for all parts of the dirt bike. Riding without an air filter can damage the entire engine and cause very bad problems, and believe me, you do not want it.

Well then, I may have upset you a little by asking that you clean your air filter after every ride, but at least your engine will stay alive and not get destroyed.

Why you can’t ride on a dirt bike without an air filter

If you are still not convinced, here is an extended explanation. I will show you the extended answer to why riding without an air filter is not recommended.

Look, riding without the air filter is super dangerous to your engine because your air filter has a lot of different functions and it may surprise you but your air filter is one of the most important parts of your dirt bike. Not only does it protect your engine, but it protects all the parts of your dirt bike. And I know it is annoying to clean the air filter constantly, but if you do not clean the air filter after every ride, you can cause a lot of problems with your dirt bike.

In general, here are all the different problems that can happen when you ride without an air filter….

  • Engine Problems – Every ride you take, regardless of how clean you the area is leaves dirt, germs, and debris that you encounter during riding. When you assemble without an air filter, all the dirt can get into your engine. The dirt can start to erode all the important components of the engine, especially the valves, which will cause tons of problems with your engine and after a few rides.
  • The Engine life will be shortened – Riding without an air filter will have a significant impact on the engine life because all the dirt that goes into the engine will make your engine very weak and vulnerable. It gets worse after every ride you take and may be destroyed after a few weeks or months; although, it depends on how powerful your engine is and how often you ride without an air filter.
  • Your engine will be less powerful and strong – Riding without the air filter will significantly reduce the power and speed of your engine to the point that your dirt bike becomes really slow. Removing the air filter interrupts and changes the fuel to air ratio, making your engine run thinner; more air makes it much less powerful.
  • Problems with all parts of the dirt bike – it may surprise you, but riding without an air filter will not only cause engine problems but many more parts of your dirt bike will be affected. Not only would you have an engine problem, but you would have a chain of additional problems that can cost you because the engine is the most important part of dirt bikes. So, know that if the engine is damaged, it will affect many more parts of your bike.

I hope you now understand why riding a dirt bike without an air filter is simply prohibited and extremely dangerous to your engine and, in general, to your entire dirt bike.

Can you ride a dirt bike with a dirty air filter?

No, Riding your dirt bike with a dirty air filter will cause your engine to run very poorly and inefficiently and you will also feel a very sharp and significant decrease in its performance. This happens because, when your air filter is dirty or clogged, it will not be able to pump enough air into the combustion chambers and from there, it will simply switch to more gas rather than air. This will significantly lower its performance and shorten engine life, which is at best while in the worst case, the dirty air will simply destroy the entire engine.

You have to understand that riding a dirty air filter is just as bad as riding without an air filter because a dirty air filter will simply block your engine from getting air into the engine, causing dirt inside the air filter to enter the engine. So, between riding without an air filter or with a dirty air filter, your engine will hit and the only option left is to simply assemble a clean air filter and make sure you clean your air filter after every ride. I wrote a guide on cleaning your air filter – Click here to see.

Also, I need to note that maintaining and keep your air filter clean can significantly extend engine life and give it even better performance in the field and you will feel how fun it is to ride a clean air filter and not a dirty air filter.

Cleaning will have to happen after every ride and I know how annoying it is to clean your air filter after every ride so I would even recommend you buy at least 4 to 3 air filters so you don’t have to clean straight after every ride. I found just the perfect air filter on Amazon and it is sold for a very low price that I was shocked – click here to view.

How to know if you need to replace your dirt bike air filter

Most average air filters will require cleaning after every ride, but there are very high-quality air filters that can hold up after even a few rides. It all depends on the quality and durability. Typically, the more expensive your air filter is, the more likely you are to get better value.

If you are confused and do not know how much rides the air filter can hold, here are some signs that you will need to identify to help you understand if your air filter needs cleaning

  • The engine makes strange noises – this is the easiest sign to identify if your air filter is very dirty and needs cleaning. As soon as your engine makes strange noises and even vibrates, it shows that the air filter is clogged with the dirt it has accumulated; so, it is important to pay attention to it.
  • The air filter looks dirty – A new air filter usually comes in white or any other color, but after a while, it accumulates dirt and turns darker. Sometimes, you can’t see the black color that the dust and dirt produce on the inside of the air filter, so it is important to take a flashlight or even just to use normal light to check if it is soiled inside.
  • Decrease in engine horsepower – when you ride, and you feel the acceleration and speed of dirt bikes is less than normal, this is a sign that your engine is not getting enough air, which lowers its performance. It is a clear sign that your air filter needs cleaning. Cleaning the air filter can increase your engine’s horsepower and acceleration by over 10.
  • Black Smoke – a sign that indicates that your air filter needs urgent cleaning is as soon as black smoke comes out of the exhaust. Usually, this happens when there is not enough air coming into the engine, causing the fuel not to burn but leave the exhaust which can be super dangerous and cause your engine to explode. It is important to note that black smoke from the exhaust only happens when you really neglected your air filter without cleaning it for a few weeks.
  • Smell of gasoline – If you smell gasoline, this means there is not enough air going into the instant or the fuel exhaust system, which means your air filter is very dirty.
