Step-by-Step Cleaning Instructions
- Remove the Air Filter Cover: Locate and unscrew the seat and side panel to access the airbox. Remove the filter carefully to avoid letting debris fall into the intake.
- Inspect the Foam Filter: Look for tears, holes, or signs of aging. Discard any filter that is damaged or excessively worn to avoid risking the engine.
- Clean the Air Filter:
- Soak the filter in warm water mixed with a small amount of mild soap or a dedicated filter cleaner.
- Gently squeeze (do not wring or twist) the filter to release trapped dirt and oil.
- Rinse in clean water until all soap and contaminants are gone.
- Dry Completely: Allow the filter to fully air-dry. Do not use compressed air or heat sources, as they can damage foam integrity. Drying in the warm sun is acceptable.
- Apply Foam Filter Oil: Work high-quality foam filter oil through every part of the filter. The foam should appear sticky but not dripping. This step is essential to trap airborne particles during riding.
- Install the Filter: Carefully place the cleaned and oiled filter back onto the airbox mount, ensuring a complete seal all the way around to prevent dust from bypassing the filter.
- Re-secure the Cover: Replace the air filter cover, seat, and side panel as originally installed.
When & How to Replace the Filter
