Kawasaki KLX140 Proprietary Cleaning Method
- Separate the foam filter from the supporting frame.
- Gently wash the filter in a bath of high flash-point solvent or a specialized filter cleaner and use a soft touch (no wringing or harsh brushing).
- Thoroughly rinse in clean water if using soap/cleaning solution.
- Squeeze excess liquid out with a towel. Never wring or twist the foam to preserve its integrity.
- Allow the filter to air dry out of direct sunlight or heat sources.
Oil and Inspection – Essential Steps
- Once dry, thoroughly inspect the foam for tears, worn spots or deteriorated areas. Replace if any damage is found.
- Saturate the filter with a high-quality foam filter oil, ensuring an even but not overdone coat. Squeeze out excess gently using a fresh towel, leaving no dry spots or drips.
