The recommended oil type for the Polaris 900 Fusion is Polaris VES Full Synthetic 2-Cycle Oil for optimal performance and protection.
If your Polaris 900 Fusion won't start, check the battery for charge, ensure the fuel is fresh, inspect the spark plugs for wear or damage, and verify that the kill switch is in the 'run' position.
For breaking in a new engine, operate at varied throttle positions for the first 10 hours, avoid prolonged idling, and refrain from full-throttle operation during the first tank of fuel.
It is recommended to inspect and potentially replace the spark plugs every 1000 miles or annually, whichever comes first, to maintain optimal engine performance.
To winterize your Polaris 900 Fusion, stabilize the fuel, change the oil, lubricate all necessary components, disconnect the battery, and store the snowmobile in a dry, covered environment.
To adjust the track tension, elevate the rear end of the snowmobile, measure the sag in the track, and adjust the tension bolts on both sides of the rear suspension until the desired tension is achieved.
If overheating occurs, check for coolant levels, ensure the radiator is not blocked, inspect the thermostat and water pump, and verify that the fan is functioning properly.
To improve fuel efficiency, ensure regular maintenance, maintain proper tire pressure, use recommended oil and fuel, and avoid aggressive riding habits.
Before each ride, check the oil level, inspect the track and skis for damage, ensure the brakes are working, verify throttle operation, and check for any loose bolts or fittings.
To replace the drive belt, remove the belt guard, relieve tension on the belt by opening the secondary clutch, remove the old belt, and install the new one, ensuring it sits properly in the grooves.
