To maintain a hot, strong spark, keep
the plug free of carbon. Remove car-
bon from the plug and adjust the gap
to 0.8 – 0.9 mm (0.031 – 0.035 in) for
good ignition. Use a thickness gauge
to check the gap.
IDLE SPEED ADJUSTMENT
To adjust the idle speed properly, you
need a tachometer. If you do not have
one, ask your Suzuki dealer or a qual-
ified mechanic to perform this adjust-
ment.
To adjust the idle speed:
1. Start the engine and warm it up.
2. Turn the throttle stop screw
1
in
or out so that the engine idles at
1400 – 1600 r/min.
CAUTION
Dirt can damage your ATV if it
enters an open spark plug hole.
Dirt can damage engine parts that
move.
Cover the spark plug hole while
the spark plug is out of the hole.

WARNING
Improper adjustment of the idle
speed can be hazardous.
An idle that is too high can cause
the ATV to lurch forward when
you shift to first gear. This may
cause an accident. Excessive
engine wear may also result if idle
speed is adjusted improperly or
when the engine is not fully
warmed up.
Adjust the idle to the correct
speed. Make sure the engine is
fully warm before adjusting the
idle speed.
