10. Remove the jumper cables in oppo-
site order of hook-up (4, 3, 2, 1). Be
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 or the car-
buretor may need to be adjusted. Consult
an authorized dealer if the plug insulator is
not a light brown color. To help prevent
cold weather fouling, make sure to thor-
oughly warm up the engine before operat-
ing.
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 0.6-0.7 mm (0.024-
0.028 in.) for proper ignition. Use a
feeler gauge to check the gap.

ened 1/8-1/4 turn once the washer contacts
the cylinder head.
