Maintenance
Carburetor
Normal wear from engine vibrations may cause the carburetor to supply an overly rich fuel
mixture. Replace the jet needle and the needle jet after every 180 hours of operation.
Idle Speed
Carburetor idle adjustments affect engine starting behavior. A proper idle speed of 1700-
1800 RPM will result in easier starting. If idle speed is unsatisfactory, make adjustments as
outlined on page 113.
Idle Speed
1. Position the vehicle on a level surface. Lock the parking
brake. Place the transmission in neutral.
2. Start the engine and allow it to idle for five minutes, or until
operating temperature is reached.
3. Turn the idle adjusting wheel (1) until idle speed reaches
1700-1800 RPM. If idle speed is unsatisfactory after per-
forming this procedure, see your Polaris dealer for informa-
tion about jetting changes.
