7. Apply Yamaha foam air filter oil or
other quality foam air filter oil to the el-
ement. If foam air filter oil is not avail-
able, motor oil may be used.
NOTE:
The element should be wet but not drip-
ping.
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 ev-
ery 20 ~ 40 hours. It should be cleaned and
lubricated more often if the machine is op-
erated in extremely dusty areas. Each time
filter element maintenance is performed,
check the air inlet to the filter case for ob-
structions. Check the air cleaner rubber
joint to the carburetor and manifold fittings
for an airtight seal. Tighten all fittings se-
curely to avoid the possibility of unfiltered
air entering the engine.
CAUTION:
Never operate the engine with the air filter
element removed. This will allow unfil-
tered air to enter, causing rapid engine
wear and possible engine damage. Addi-
tionally, operation without the filter ele-
ment will affect carburetor jetting with
subsequent poor performance and possi-
ble engine overheating.
