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.)
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.
If the engine idle speed is not satisfactory, and all other conditions are
favorable, the carburetor can be adjusted.
1. Place the transmission in
gear.
2. Lock the parking brake.
3. Operate the engine for
about five minutes.
4. Turn the carburetor idle
adjuster (1) either in or out
until the desired idle RPM is
reached. Turning the adjuster
in (clockwise) will raise
RPM. Turning the adjuster
out (counterclockwise) will
lower RPM.
