How to Change an Air Filter on a YZ 125

Dirt bikes such as the Yamaha YZ 125 take a lot of abuse and also see a lot of time in dirty areas. This can quickly jam up your air filter, making the engine run poorly because it's starved for air. As a result, every few times you go out riding, you should change or clean your filter to make sure everything functions properly. This is not a difficult process and can be done in less than15 minutes or so.

Things You'll Need

• Replacement air filter
• Air filter oil

Instructions

1. Park the YZ 125 on a stand so that it won't move or go anywhere. Then lift up the seat and set it to the side.

2. Reach inside and locate the wing nut holding the air filter to the throttle body. Pull the air filter out of the compartment and set it to the side.

3. Peel the foam air filter off of the plastic base. Spray the oil onto the replacement filter, if it doesn't already come pre-oiled. Then wrap the replacement filter onto the plastic base.

4. Reach inside the hole in the frame and install the replacement filter on the throttle body using the factory wing nut. Reinstall the seat.
