5. Inspect the element. If damaged,
replace it.
6. Apply Yamaha foam air filter oil or other
quality foam air filter oil to the element.
If foam air filter oil is not available,
SAE10W30 motor oil may be used.
NOTE:
The element should be wet but not dripping.
7. Reinstall the element and front cover.
NOTE:
The air filter element should be cleaned
every 20 ~ 40 hours. It should be cleaned and
lubricated more often if the machine is oper-
ated in extremely dusty areas. Each time fil-
ter element maintenance is performed, check
the air inlet to the filter case for obstructions.
Check the air cleaner rubber joint to the car-
buretor and manifold fittings for an air-tight
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, opera-
tion without the filter element will affect car-
buretor jetting with subsequent poor perfor-
mance and possible engine overheating.
