ADJUSTMENTS
Carburetor
Your POLARIS ATV is calibrated at the factory for optimal perfor-
mance at altitudes ranging from zero to 8,000 feet (2400 m) and temper-
atures above 15° F (-9° C). Refer to the specifications section beginning
on page 96 for carburetor and jetting specifications.
Any jetting changes must be made only by an authorized POLARIS
dealer. Always see your dealer if jetting changes are needed.
Tip: 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.
Carburetor/Engine Idle RPM Adjustment
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. Start the engine and allow it to warm up for approximately five min-
utes.
4. Turn the carburetor idle screw in (clockwise) to raise RPM. Turn the
screw out (counterclockwise) to lower RPM.
