Proprietary Air Filter Cleaning Steps by MotoSport
-
Access the Air Filter
- Remove the seat and side panels to locate the air box. Unscrew the airbox cover using a 5 mm Allen key.
- Gently pull out the air filter, avoiding contact with the intake tract to prevent dirt falling in.
-
Inspect for Dirt, Damage – Replace if Needed
- If the filter is torn, excessively dirty, or cannot be adequately cleaned, replace with a compatible cotton/oil high-flow filter or original paper element.
- Always check the sealing surfaces and gasket for undamaged fit.
-
Clean the Filter (Reusable Type Only)
- Tap the filter gently to dislodge loose debris.
- Rinse with cool water from the inside out to prevent embedding particles deep into the fibers.
- Apply a specialized air filter cleaner; allow to soak for 10 minutes, then rinse thoroughly.
- Air dry completely–never use compressed air, which may damage the filter medium.
- Re-oil per filter instructions (typically a light, even coat of foam air filter oil if not pre-oiled).
-
Reinstall
- Place the clean or new filter into the airbox, ensuring perfect alignment and seal.
- Reinstall the airbox cover securely and refit seat and panels.
