Air Filter Cleaning & Replacement Guide for 1986 Kawasaki KX60
Shop parts for a 1986 Kawasaki KX60 Dirt Bike.
Keeping the air filter clean – and replacing it as needed – is key to the performance and longevity of your 1986 Kawasaki KX60. This model uses a dual-layer foam filter that delivers both maximum filtration and strong airflow, ensuring the two-stroke engine gets clean air for peak power and reliability.
Unique Features of the 1986 KX60 Air Filter
- Dual-stage foam construction: The filter features a coarse, open-pore outer foam layer to capture sand, grime, and larger airborne dirt. Inside, a fine open-pore foam acts as a second barrier, trapping even the smallest particles while passing high volumes of air for performance.
- Fused design: Outer and inner foam layers are bonded, preventing dirt from getting trapped between layers and stopping glue seams from breaking down – even after repeated cleanings.
- Washability and reuse: Proper cleaning allows a quality foam filter to be reused up to 15 times.
- Sealing ring: A thick, flat foam sealing ring ensures maximum contact with the airbox, reducing the risk of leaks and unfiltered air intake.
Proprietary MotoSport 1986 KX60 Air Filter Care Instructions
- Remove the seat & airbox cover using your preferred tools. Carefully extract the filter from the airbox.
- Inspect for damage: Check for rips, tears, or breakdown in the foam, glue seams, and sealing ring. Replace the filter immediately if you see issues.
- Pre-clean: Gently tap or shake loose dust & dirt. Avoid hitting or squeezing the foam excessively, which damages cells.
- Wash: Using a dedicated foam filter cleaner or a mild soap solution, immerse and gently work out old oil, dirt, and grime. Do not use gasoline or heavy solvents – these break down foam and adhesives.
- Rinse thoroughly: Rinse under low-pressure water until no suds remain. Squeeze out water – never wring or twist the foam, as this may tear or deform it.
- Dry: Air-dry the filter away from direct sunlight or heat. The foam must be fully dry before oiling.
- Oil: Use high-quality foam filter oil. Pour or spray oil evenly throughout the filter, working it gently to ensure thorough saturation of every cell. Do not over-oil – excess oil can choke air flow.
- Install – seal properly: Refit the filter carefully, confirming that the sealing ring contacts the airbox evenly. For extra leak protection, apply a thin bead of waterproof filter grease to the sealing surface.
- Reassemble and start up: Replace airbox lid & seat. Start your KX60 – check for ease of breathing and steady idle.
When to Replace the Air Filter
- Replace the air filter if the foam feels brittle, shows rips, or glue seams are degraded.
- If the filter remains heavily soiled after cleaning, or after significant exposure to water – such as deep mud rides – replacement secures engine safety.
- MotoSport recommends checking the filter after each ride in dry, dusty conditions – and cleaning every 2–4 hours of operation in sandy or muddy terrain.
Important Notes for KX60 Owners
- The 1986 Kawasaki KX60 is renowned for its light weight and peaky two-stroke engine – meaning unrestricted airflow is critical for top-end performance.
- The dual-layer foam filter is engineered specifically for the size and airflow requirements of the KX60 – using generic filters may reduce engine power and increase airbox leaks.
- Always install the correct filter part number for the 1986 KX60 – confirm fitment before purchase.
Your KX60 deserves clean air for every ride. Regular cleaning & proper filter replacement protect your engine and help maintain that legendary Kawasaki snap.
