ADJUSTMENTS

Carburetor

This vehicle is calibrated at the factory for optimal performance at alti-

tudes 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 opera-

tion. 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 PVT or engine

damage. See your Polaris dealer for more information about jetting 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 minutes.

4. Turn the screw in (clockwise)

to raise RPM. Turn the screw
