Step-by-Step: Cleaning the 1988 CR500 Air Filter
-
Remove the Seat & Filter:
Release the seat bolts and lift the seat off. Remove the airbox cover, then carefully extract the air filter. Avoid dropping dirt into the intake. -
Inspect the Filter for Damage:
Look for tears, seam failure, or signs of deterioration. Replace if necessary. -
Pre-Clean:
Tap the filter gently to remove loose dirt. Do not use compressed air, as it can damage the foam. -
Wash the Filter:
Soak the filter in a dedicated cleaner or a mild soap solution. Gently squeeze (never wring) to remove dirt. Rinse with warm water until all soap and debris are gone. -
Dry Thoroughly:
Squeeze out excess water and let the filter air dry completely. Do not use heat sources, which can warp or weaken foam. -
Apply Air Filter Oil:
Evenly work fresh air filter oil into the dry filter. Ensure every section of foam is fully saturated but not dripping. This sticky oil traps the finest particles. -
Reinstall Following a Light Seal:
Apply a thin layer of sealing grease to the edge of the filter. Reinstall into the airbox, making sure it's properly seated to prevent unfiltered air bypass. -
Replace the Seat & Airbox Cover:
Secure everything in the reverse order of removal.
Replacing the Air Filter
