NOTE: This ATV uses resistor-type spark plug to avoid jamming electronic
parts. Improper spark plug selection may cause electronic interference with
your ATVs ignition system, resulting in the vehicle performance problems.
Use recommended spark plugs.
To install a spark plug turn it in as far as possible with your fingers, then
tighten it with a wrench.
CAUTION
Improper installation of the spark plug could damage your ATV.
An overly tight or cross threaded spark plug will damage the aluminum
threads of the cylinder head.
Carefully install spark plug by hand. If the spark plug is new, tighten it
with a wrench about ½ turn past finger tight. If you are reusing the old
spark plug, tighten it with a wrench about 1/8 turn past finger tight.
CAUTION
Dirt could damage your ATV if it entered an open spark plug hole of cylinder
head.
Dirt could damage engine parts that move.
Cover the spark plug hole while the spark plug is out of the hole.
To maintain a proper functioning spark
plug, keep the plug free of carbon.
Remove carbon from the plug with a wire
or pin, and adjust the gap to 0.6~0.7mm
(.024 - .028 in) for good ignition. Use a
thickness gauge to check the gap.
