Carburetor Adjustments
Your Polaris ATV is calibrated at the factory for optimal performance at altitudes ranging
from zero t o 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 t he 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: C ontinuous 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 t he ATV for
conditions in your area.
