Spark Plugs

This vehicle comes equipped with speci-
fied spark plugs. See the specifications
chart for the correct spark plugs. A light
brown insulator 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 dealer if
the plug insulator is not a light brown
color. To help prevent cold weather foul-
ing, 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 (see 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 con-
tacts the cylinder head. A used spark plug
should be tightened 1/8 - 1/4 turn once the
washer contacts the cylinder head.

Air Filter/Housing Drain

The air filter inside the air filter housing
must be kept clean to provide good engine
power and gas mileage. If the vehicle is
used under normal conditions, service the
filter at the intervals specified. If operated
in dusty, wet, or muddy conditions, inspect
and service the filter more frequently. Use
the following procedure to remove the fil-
ter and inspect and/or clean it.
Failure to inspect the air filter fre-
quently if the vehicle is used in dusty,
wet, or muddy conditions can dam-
age the engine.

above and in front of the rear right
wheel.
1. Remove dirt and debris from around
the filter housing.
