7. Apply Yamaha foam air filter oil or other
quality foam air filter oil to the air filter ele-
ment.
NOTE:
The air filter element should be wet but not drip-
ping.
8. Pull the air filter element over its frame,
and then install the lock plate by turning it.
9. Install the air filter element assembly.
10. Install the air filter case cover by hooking
the fasteners onto the air filter case.
11. Install the seat.
NOTE:
The air filter element should be cleaned every
20-40 hours. It should be cleaned and lubricated
more often if the machine is operated in
extremely dusty areas. Each time the air filter
element 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
unfiltered 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,
operation without the air filter element will
affect carburetor jetting with subsequent
poor performance and possible engine
overheating.
