7. Apply Yamaha foam air filter oil or other
quality foam air filter oil to the element. If
foam air filter oil is not available, motor oil
may be used.
NOTE:
The element should be wet but not dripping.
8. Reinstall the element to the element
guide.
9. Reinstall the element assembly and parts
removed for access.
1. Connect hose
NOTE:
The air filter element should be cleaned every
20 ~ 40 hours. It should be cleaned and lubri-
cated more often if the machine is operated in
extremely dusty areas. Each time filter ele-
ment maintenance is performed, check the air
inlet to the filter case for obstructions. Check
the air cleaner rubber joint to the carburetor
and manifold fittings for an airtight seal. Tight-
en all fittings securely to avoid the possibility
of unfiltered air entering the engine.
CAUTION:
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, op-
eration without the filter element will affect
carburetor jetting with subsequent poor
performance and possible engine over-
heating.
