MAINTAINING THE AIR FILTER
Failure to maintain the air filter can result in poor performance or
can cause permanent damage to the engine. Engine failure due to
improper air filter maintenance is not covered by the product warranty.
Cleaning the Air Filter

cover (Fig. 31).
2. Slide the air filter cover off of the air filter housing (Fig. 31
).

. Remove the sound filter and media filter from the air filter
housing (Fig. 32).
4. Gently hand wash the sound filter and media filter in detergent
and water. Rinse the filters thoroughly and allow them to dry.
5. Lightly coat the sound filter with clean SAE 30 oil. DO NOT
apply oil to the media filter. Squeeze the sound filter to spread
and remove excess oil.
6. Squeeze the sound filter and insert it in
to the space between the
t
wo ram horn openings (Fig. 32). Make sure the sound filter is
pushed all the way in so that it completely covers both openings
