Proprietary MotoSport Air Filter Inspection – Cleaning Process

1. Remove the Seat:
   Release the seat latch at the rear. Lift the seat off to access the air filter assembly.
2. Extract the Filter:
   Loosen the filter retaining wing nut. Carefully draw the filter straight out to avoid dropping dirt into the intake tract.
3. Initial Inspection:

4. Pre-Cleaning:
   Gently tap the filter to dislodge loose debris. Never use compressed air or aggressive handling that may damage the filter media.
5. Washing:
   
   • Use a dedicated, biodegradable filter cleaner for foam filters.
   • Immerse and squeeze – never wring – until clean.
   • Rinse thoroughly with cool water until water runs clear. Allow to air dry completely.
6. Re-Oiling:
   
   • Use a premium foam filter oil designed for off-road bikes.
   • Apply evenly and work through the filter until fully saturated but not dripping.
   • Wipe excess oil with a lint-free cloth. Leave it for 15 minutes to ensure oil penetration.
7. Reinstallation:
   Check the airbox for dirt or water – clean as needed. Insert the air filter securely, ensuring it seals completely along the edge. Tighten the retaining nut, but do not overtighten.
8. Fit the Seat:
