Air Cleaner
4. Loosen the screw (4) and remove the air cleaner assembly (5)
from the air cleaner housing.
5. Remove the clamp (6).
6. Remove the air cleaner (7) from the air cleaner body (8).
7. Gently wash the air cleaner in clean, non-flammable (high flash
point) solvent such as kerosene — not gasoline. After cleaning,
gently squeeze out the remaining solvent. Avoid twisting or
wringing the air cleaner. This can tear the foam.
8. Inspect for tears or cracks in the foam or seams of the air cleaner.
Replace the air cleaner if it is damaged.
9. Allow the air cleaner to dry thoroughly before applying oil. A wet
air cleaner will not fully absorb the oil.
10. Pour clean Pro Honda Foam Filter Oil or an equivalent (Canada:
Honda Foam Filter Oil or an equivalent) over the entire surface of
the air cleaner. Use both hands to evenly spread the oil into the
air cleaner. Gently squeeze out any excess oil. (To keep your
hands dry, place the air cleaner in a clean plastic bag before
spreading the oil into the air cleaner.)
