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 1500-1600 RPM will
result in easier starting. If idle speed is unsatisfactory,
use the following procedure to make adjustments.
1. Position the vehicle on a level surface.
2. Lock the parking brake. Place the transmission in
neutral.
3. Start the engine and allow it to idle for five min-
utes, or until operating temperature is reached.
4. Turn the idle adjusting wheel (1) until idle speed reaches 1500-1600 RPM.
5. If idle speed is unsatisfactory after performing this procedure, see your Polaris dealer for
information about jetting changes.
