MAINTENANCE Storage (Cont.) 7.Drain the recoil housing. 8.Block the ATV so all tires are suspended off the ground. 9.Add Polaris Premium Storage Stabilizer to the fuel tank (PN 2871326). 10.Cover the ATV with a canvas cover.

Carburetor Adjustments If the vehicle is to be operated at various altitudes and temperatures, certain adjustments can be made to improve its operation and driveability. Above 6000 feet (1800 m) the engine air/fuel mixture becomes overly rich. An engine loses approximately 3% of its power for each 1000 foot (304.8 m) increase in elevation. Although this power cannot be regained, changes to the carburetor and drive system can be made to allow efficient operation. These changes include: 1.Carburetor re-jetting to compensate for altitude and/or temperature changes. 2.Transmission convertor modification to adjust for engine horsepower loss during high altitude operation. Contact your dealer. 3.On 2 cycle models, air screw adjustments can be made to compensate for temperature changes and/or changes in altitude. 4.On 4-cycle models, pilot screw adjustments can be made to compensate for temperature changes and/or changes in altitude. NOTE: Contact your dealer for altitude adjustments. They have the training and special tools required to perform all necessary modifications for you.
