careful not to short cables against
bare metal.

NOTE: Have the battery and elec-
trical system checked prior to oper-
ating the vehicle again.

Spark Plug

The ATV comes equipped with a specified
spark plug. See the specifications chart for
the correct spark plug. A light brown insu-
lator indicates that the plug is correct. A
white or dark insulator indicates that the
engine may need to be serviced. Consult
an authorized Arctic Cat ATV dealer if the
plug insulator is not a light brown color.
To help prevent cold weather fouling,
make sure to thoroughly warm up the
engine before operating.
To maintain a hot, strong spark, keep the
plug free of carbon.
Before removing the spark plug, be sure
to clean the area around the spark plug. If
you do not, dirt could enter engine when
removing or installing the spark plug.
Adjust the gap to specified amount (see
appropriate specifications chart) for
proper ignition. Use a feeler gauge to
check the gap.
When installing the spark plug, be sure to
tighten it securely. A new spark plug
should be tightened 1/2 turn once the
washer contacts the cylinder head. A
used spark plug should be tightened 1/8 -
1/4 turn once the washer contacts the cyl-
inder head.
Throttle Cable
Adjustment
To adjust the throttle cable free-play:
1. Loosen the jam nut from the throttle
cable adjuster.
2. Slide the rubber boot away and turn the
adjuster until the throttle lever has
proper free-play of 3-6 mm (1/8-1/4 in.).
3. Tighten the jam nut against the throt-
tle cable adjuster securely; then slide
ATV-0051
the rubber boot over the adjuster.

Air Filter

The air filter inside the air filter housing
must be clean to provide good engine
power and gas mileage. If the ATV is used
under normal conditions, service the filter
at the intervals specified in the Mainte-
nance Schedule. If operated in dusty, wet,
or muddy conditions, inspect and service
the filter more frequently.
