MAINTENANCE AND LUBRICATION Adjustments Carburetor IMPORTANT: 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. Start the engine. 2. Lock the parking brake. 3. Allow the engine to run for approximately five minutes. 4. Adjust the carburetor idle screw either in or out until the desired idle RPM is reached. Turning the screw in (clockwise) will raise RPM. Turning the screw out (counterclockwise) will lower RPM. 90

Carburetor
IMPORTANT:
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.
Start the engine.
2.
Lock the parking brake.
3.
Allow the engine to run for approximately five minutes.
4.
Adjust the carburetor idle screw either in or out until the desired
idle RPM is reached. Turning the screw in (clockwise) will raise
RPM. Turning the screw out (counterclockwise) will lower RPM.
