ADJUSTMENTS
Carburetor/Idle RPM
Your Polaris ATV is calibrated at the factory for optimal performance
at altitudes ranging from zero to 6,000 feet (1800 m) and temperatures
of +40 degrees F. (4 degrees C.) or higher. Above 6000 feet (1800 m)
the engine air/fuel mixture becomes overly rich and the engine loses
approximately 3% of its power for each 1000-foot (304.8 m) increase
in elevation. Although this power cannot be regained, adjustments to
the carburetor and drive system can be made to allow more efficient
operation. Optional jets, available from your Polaris dealer, are
required for operation above 6, 000 feet and temperatures below +40
degrees F. (4 degrees C.)
If the engine idle speed is not satisfactory, and
all other conditions are favorable, the carburetor
can be adjusted.
1. Warm up the engine by running the vehicle
for approximately five minutes.
2. Place the transmission in gear with the
parking brake applied.
3. Adjust the carburetor idle screw (1) either in
or out until the desired idle RPM is reached.
Turning the screw in (clockwise) will raise
RPM. Turning t he screw out
(counterclockwise) will lower RPM.
NOTE: Continuous operation of the engine without proper jetting
when required can cause poor performance, overheating or
engine damage. See your Polaris dealer for more information
about jetting the ATV for conditions in your area.
