Paper filters are usually found on older bikes, while foam filters are more common on newer models. Whichever type of filter you have, be sure to follow the manufacturer’s instructions for cleaning or replacement.

How to Clean Your Dirt Bike’s Air Filter
A clean air filter is essential to the performance of your dirt bike. A clogged air filter will restrict airflow to the engine, which can lead to a loss of power. In this step-by-step guide, we’ll show you how to clean your dirt bike’s air filter so you can keep your bike running at peak performance.
Step 1: Remove the Air Filter
The first step is to remove the air filter from the bike. Most dirt bikes have an access panel on the side of the engine that allows you to get to the air filter. Once you’ve located the access panel, remove the bolts or screws that are holding it in place and set them aside. Then, carefully remove the air filter and set it aside.
Step 2: Clean the Air Filter Housing

Use a soft brush or cloth to remove any dirt or debris from the air filter housing. Be sure to get into all of the nooks and crannies so that no foreign objects are left behind. Once you’re satisfied that the housing is clean, set it aside and move on to Step 3.
Step 3: Clean the Air Filter Elements

The next step is to clean the filter elements themselves. Start by tapping them gently on a hard surface to loosen any caked-on dirt. Then, use a soft brush or cloth to remove any remaining dirt. Once both sides of the elements are clean, set them aside and move on to Step 4.
Step 4: Inspect the Air Filter Elements for Damage
After you’ve cleaned both sides of the air filter elements, it’s time to inspect them for damage. Look for any cracks, tears, or holes in the elements. If they’re damaged, they need to be replaced. However, if they’re in good condition, you can move on to Step 5.
Some air filters can be washed with soap and water if they’re particularly dirty. However, be sure to check your owner’s manual before doing this as some manufacturers recommend against it. Washing your air filter elements with soap and water can damage them and cause them to break down prematurely.
If your air filter elements are reusable, they can be reused after they’ve been cleaned and inspected for damage. However, if they’re disposable, you’ll need to buy new ones.
Step 5: Reassemble Your Dirt Bike’s Air Filter
The last step is to reassemble your dirt bike’s air filter—starting with the housing first and then adding the element(s). Once everything is back in place, replace the access panel and secure it with bolts or screws. And that’s it! You’ve successfully cleaned your dirt bike’s air filter!
Conclusion:
Cleaning your dirt bike’s air filter is essential to keeping it running at peak performance levels. By following this simple guide, you can easily do it yourself in just a few minutes’ time! Just remember: if your air filter elements are damaged, be sure to replace them before putting everything back together again
