7. Apply Yamaha foam air filter oil or other
quality foam air filter oil to the sponge
material.
NOTE:
The sponge material should be wet but not drip-
ping.
8. Install the sponge material onto its frame
and install the screw.
9. Install the air filter element.
10. Install the air filter case cover by installing
the screws.
11. Install the seat.
NOTE:
The air filter element should be cleaned every
20–40 hours. It should be cleaned and lubricat-
ed more often if the machine is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the filter case for obstructions. Check the
air filter case rubber joint to the carburetor and
manifold fittings for an airtight seal. Tighten all
fittings securely to avoid the possibility of unfil-
tered air entering the engine.
cC
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, opera-
tion without the air filter element will affect
carburetor jetting with subsequent poor per-
formance and possible engine overheating.
