Keeping the air filter clean and properly replaced on your 2002 Suzuki RM85 is essential for performance, engine longevity – and ensures your MotoSport experience is trouble-free every ride. The RM85's high-revving 2-stroke engine is particularly sensitive to proper air intake and filtering, making this procedure crucial.

Step-by-Step Air Filter Cleaning & Replacement

  • Removal: Begin by removing the seat and side cover to access the air box. Unscrew and carefully twist off the filter; take care not to let debris fall into the intake tract. Inspect the filter cage note the RM85 air filter cage has precise hole alignment for two on one side, one on the other; ensure proper fitment when re-installing.
  • Cleaning: If reusing, gently tap the filter to dislodge dirt. Wash the foam filter in a dedicated air filter cleaner or mild soap and water. Rinse thoroughly, then allow the filter to dry fully. Never wring out the foam harshly as it may tear.
  • Inspection: Check for damage, thinning, or tears in the foam. If any are found always replace with a new filter to avoid engine damage. For the RM85, MotoSport recommends keeping a spare filter readily available to maximize ride time and minimize downtime.
  • Oiling: Apply high-quality foam filter oil generously. Distribute oil evenly by hand, ensuring it penetrates the foam. Pay special attention to the sealing rim of the filter; applying a light bead of filter grease around the edge can further enhance the seal and block micro-dust.
  • Replacement: Mount the filter onto the cage. Align the holes on the cage and filter properly incorrect fitment can leave unfiltered gaps. Insert assembly into the airbox, securing with the retention screw. Double check for proper seal along the filter rim before reinstalling seat and side panel.
