often if the ATV is operated in extremely dusty ar-

is performed, check the air inlet of the air filter case
for obstructions.

CAUTION:
G Make sure that the air filter element is prop-
erly seated in the air filter case.
G Never operate the engine with the air filter el-
ement removed. This will allow unfiltered air
to enter the engine, causing rapid engine
wear and possible engine damage. Addition-
ally, operation without the air filter element
will affect carburetor jetting with subsequent
poor performance and possible engine over-
heating.
