8. Check the sponge material and replace it if

damaged.

9. Apply Yamaha foam air filter oil or other qual-

ity foam air filter oil to the sponge material.

TIP

The sponge material should be wet but not drip-

ping.

10. Pull the sponge material over the air filter ele-

ment frame, and then install the lock plate.

11. Insert the air filter element into the air filter

case, and then install the air filter case cover

by hooking the holders onto the air filter case.

NOTICE: Make sure that the air filter ele-

ment is properly seated in the air filter

case. Never operate the engine with the air

filter element removed. This will allow un-

filtered air to enter the engine, causing rap-

id 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.

12. Install the seat.

TIP

The air filter element should be cleaned every 20–

40 hours. It should be cleaned and lubricated more

often if the ATV is operated in extremely dusty ar-

eas. Each time the air filter element maintenance

is performed, check the air inlet of the air filter case

for obstructions. Check the air filter case rubber

joint to the carburetor fittings and the rubber joint

manifold fittings for an air-tight seal. Tighten all fit-

tings securely to avoid the possibility of unfiltered

air entering the engine.
