IMPORTANT: Your Polaris ATV 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 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 per-
formance, overheating or engine damage. See your Polaris dealer for more information about
jetting the ATV for conditions in your area.
