Proprietary MotoSport Cleaning – Replacement Process
- Remove the Seat and Side Panel: Release the seat latch and unbolt the side panel for access to the airbox.
- Remove the Air Filter: Unscrew or unclip the filter retainer – carefully pull the filter and its cage out of the airbox.
- Inspect: Look for tears, worn spots, or loose seams. Replace immediately if damage is found.
- Wash: Submerge the foam filter in an approved foam filter cleaning solution or use dish soap and warm water. Gently massage and squeeze (do not twist) to remove debris and oil.
- Rinse: Rinse thoroughly with warm water to remove all soap and debris. Repeat washing if filter is still discolored or dirty.
- Dry: Gently squeeze out excess water, then air dry naturally. Do not use heaters or open flames. Inspect again for damage before oiling.
- Oil: Apply a high-quality foam filter oil once completely dry. Massage to saturate the foam evenly and remove any excess.
- Reinstall: Reassemble the filter cage and securely seat the filter back in the airbox. Ensure the sealing edges are aligned and tight.
- Replace Panels: Reinstall the side panel and seat. Confirm all fasteners are secure and the airbox is properly sealed.
