- Clean the filter regularly—typically after 3-5 hours of riding, but more often if riding in severe environments.
- Replace the filter if you notice tears, thinning, or excessive wear after a few cleaning cycles, as micro-damage can allow contaminants to enter the engine.

- Foam air filter oil (ensure compatibility with your chosen cleaner)
- Disposable gloves
- Clean towels or paper towels
- Grease (for sealing filter rim)
Step-By-Step Cleaning Guide
- Remove the Seat & Airbox Cover: Use the quick-release system to remove the seat and unclip the airbox cover. Carefully release the air filter from the cage by pressing the designated tabs.
- Inspect and Pre-Clean: Check for tears or damage. Tap the filter gently to dislodge loose debris. Wipe around the airbox opening to prevent dirt from entering during reinstallation.
- Clean the Air Filter: Submerge the dirty filter in a container with cleaner, gently working it with your hands. Avoid wringing or twisting the foam to prevent damage. Let it soak for about 15 minutes to loosen stubborn grime. Rinse thoroughly with water until all dirt and cleaner are flushed out, then gently squeeze out the waterdo not twist or wring.
- Dry Completely: Allow the filter to dry indoors, away from direct sunlight or excessive heat, to prolong foam life.
- Apply Air Filter Oil: Once dry, saturate the filter with foam air filter oil. Work the oil through evenly by hand or inside a clean plastic bag. Gently squeeze out any excess.
- Grease the Sealing Edges: Apply a thin layer of grease to the outer seal of the filter and to the sealing surface in the airbox. This prevents unfiltered air from bypassing the filter.
- Reinstall the Filter: Carefully align the filter onto the cage, ensuring a secure seal all around. Replace the airbox cover and seat.

- Avoid using automotive solvents or household detergents—only use products designed for foam motorcycle air filters.
- Keep a spare, pre-oiled filter ready to minimize downtime between rides.
