IDLE SPEED ADJUSTMENT
To adjust the idle speed properly, you need a tachometer. If you do not have
one, ask your authorized service center to perform this adjustment.
To adjust the idle speed:
1. Start the engine and warm it up.
2. Turn the engine idle screw in or out so that the engine idle speed is at
1450~1550 r/min.

WARNING
Improper adjustment of the idle speed could be hazardous.
An idle speed that is too high could cause the ATV to launch forward
when you start the engine. 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 engine
idle speed.
Inspect the fuel hose for damage
and fuel leakage. If any defects
are found, the fuel hose must be
replaced.
