Shop parts for a 2022 Kawasaki KX85 Dirt Bike.
Keeping the air filter on your 2022 Kawasaki KX85 clean and properly oiled is a must for maintaining peak performance and protecting your engine from harmful dirt and debris. This MotoSport proprietary guide details the best practice for cleaning and replacing your KX85 air filter, making maintenance hassle-free and your bike race-ready every ride.
Why Regular Air Filter Maintenance Matters
- Protects engine components from fine dust and dirt that causes premature wear
- Improves throttle response and power delivery
- Extends the life of your engine by ensuring only clean air enters the combustion chamber
Tools & Supplies Required
- 8mm socket or T-handle wrench
- Quality air filter cleaner or mild dish soap
- Air filter oil
- Nitrile gloves
- Clean towels or paper towels
- Grease (optional, for sealing the airbox rim)
Step-by-Step Air Filter Removal
- Remove the seat: Use an 8mm socket to take out the two seat bolts, then lift the seat off to reveal the airbox.
- Remove the filter: Unscrew the wingnut holding the filter cage in place. Carefully pull out the air filter and cage as one unit.
- Inspect the airbox: Wipe any debris from the inside of the airbox with a damp towel. Avoid getting dirt into the intake tract – never let anything drop inside.
Cleaning the Air Filter
- Remove the filter from the cage carefully. Avoid pulling or tearing the foam.
- Apply air filter cleaner: Soak the filter thoroughly with a dedicated air filter cleaner or a mild dish soap solution. Gently work the cleaner through the foam with your hands (wear gloves).
- Rinse and repeat: Rinse the filter under cool water. Repeat the cleaning until all dirt and oil are removed, and rinse until the water runs clear.
- Dry completely: Squeeze out excess water (do not twist – it can damage the foam). Allow the filter to air dry fully before oiling.
Oiling the Air Filter
- Apply filter oil: Using a high-quality air filter oil, fully saturate the filter. Knead the oil into the foam so every part is evenly coated but avoid over-oiling.
- Remove excess oil: Squeeze out any excess oil. The filter should be tacky but not dripping.
- Optional: Apply a thin layer of waterproof grease to the filter's sealing flange to prevent dust from leaking past the seal.
Reinstalling the Filter
- Mount the filter back on the cage and make sure it seats correctly with no gaps around the edge.
- Insert into the airbox: Ensure proper alignment and install the wingnut securely.
- Reinstall the seat: Line up and tighten the two 8mm bolts.
Replacing the Air Filter
If your KX85 air filter is torn, has degraded foam, or can't be cleaned effectively, it's time to replace it. MotoSport stocks OEM and high-performance replacement filters designed for a perfect fit on your model year.
2022 Kawasaki KX85 Specific Notes
- The KX85's compact airbox is vulnerable to dirt entry during service. Always use care and block the intake with a clean rag if needed during deep cleaning.
- The filter mount uses a center wingnut – avoid over-tightening as this can warp the cage or cross-thread the stud.
- Some owners prefer to swap a spare freshly-oiled filter between motos for maximum airflow and convenience.
Following this MotoSport guide ensures maximum engine protection and reliable performance for your 2022 Kawasaki KX85. Remember – clean and oil your filter after every ride in dusty or muddy conditions, or at least every few rides in normal conditions. Keep an extra filter ready to go in your MotoSport parts locker for hassle-free swaps.
