- Filter Removal:– Carefully lift out the filter, minding any dirt around the air boot. Visually inspect the air boot for contamination and wipe clean with a lint-free rag. Any dirt here should be removed before installing the new or cleaned filter.
- Filter Cleaning:– Rinse the foam filter gently in a specialized air filter cleaner or low-flash-point solvent. Avoid gasoline, which can damage foam structure. Compress (never wring) to remove excess fluid.
- Drying:– Allow the filter to dry completely in open air. Never use direct heat sources.
- Oiling:– Evenly saturate the foam with quality foam air filter oil. Work the oil thoroughly through the filter using your hands in gloves or a sealable plastic bag. Uneven coverage allows dirt passage; look for full, even coloration. Use biodegradable oil only if specified by packaging.
- Seal Grease (Critical for the CR80):– Apply waterproof grease to the perimeter of the filter's sealing surface. This prevents leaks and ensures a tight sealespecially important given the CR80's airbox design.
- Reinstallation:– Place the filter back onto its cage inside the airbox. Confirm all tabs and surfaces are aligned and fully seated. Replace cover, seat, and side panel.
