Step-by-Step: Cleaning the KLX140 Air Filter
- Remove the Seat: Release the seat latch and pull the seat away to access the air box.

- Wash the Filter: Gently massage the filter in warm water with foam filter cleaner. Avoid wringing or stretching the foam. Rinse several times until all dirt and oil are removed.
- Dry Completely: Squeeze excess water from the filter and let it air dry thoroughly–never use heat to accelerate drying.
- Oil the Filter: Once completely dry, saturate the entire foam element with high-quality foam air filter oil. Work the oil in evenly. The filter should be uniformly tacky but not dripping.
