Checking the spark plugs
The spark plugs are important engine compo-
nents, which are easy to check. Since heat and de-
posits will cause any spark plug to slowly erode,
the spark plugs should be removed and checked in
accordance with the periodic maintenance and lu-
brication chart. In addition, the condition of the
spark plugs can reveal the condition of the engine.
To remove a spark plug
1. Remove the spark plug cap.
2. Remove the spark plug as shown, with thespark plug wrench included in the owner’s tool
kit.
To check the spark plugs
1. Check that the porcelain insulator around the
center electrode of each spark plug is a medi-
um-to-light tan (the ideal color when the ATV
is ridden normally).
2. Check that all spark plugs installed in the en-
gine have the same color.TIP

If any spark plug shows a distinctly different color,
the engine could be operating improperly. Do not

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.

Cleaning the spark arrester
Be sure the exhaust pipe and muffler are cool be-
fore cleaning the spark arrester.
1. Remove the screws.2. Remove the tailpipe by pulling it out of the
muffler.
3. Tap the tailpipe lightly, and then use a wire
brush to remove any carbon deposits from the
spark arrester portion of the tailpipe and inside
of the tailpipe housing.

Adjusting the engine idling speed
The engine idling speed must be checked and, if
necessary, adjusted as follows at the intervals
specified in the periodic maintenance and lubrica-tion chart.
TIP


A diagnostic tachometer is needed to make this
adjustment.

The carburetor synchronization and the throttle
cable free play must be checked, and adjusted if
necessary, before adjusting the engine idling
speed.
1. Start the engine and warm it up.
TIP

The engine is warm when it quickly responds to the
throttle.
2. Attach the tachometer to the spark plug lead.
3. Turn in both pilot air screws until they lightly
seat.
4. Turn out both pilot air screws to specification.

section on the page 8-23.)
