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.

should be tightened 1/8 - 1/4 turn once the
washer contacts the cylinder head.
