Polaris 120 Indy Owner's Manual

To maintain your Polaris 120 Indy, regularly check and replace the spark plug, inspect the drive belt, clean the air filter, and ensure all nuts and bolts are tight. Lubricate the suspension and steering components, and verify that the fuel system is clean.
If your Polaris 120 Indy won't start, check the fuel supply, inspect the spark plug for fouling, ensure the kill switch is in the 'Run' position, and verify the battery is charged. Also, check for any blown fuses or disconnected wires.
Poor performance can be due to a dirty air filter, fouled spark plug, or worn drive belt. Ensure the carburetor is clean and properly tuned. Check for proper track tension and alignment, as well as any obstructions in the exhaust system.
The Polaris 120 Indy requires unleaded gasoline with a minimum octane rating of 87. Avoid ethanol-blended fuels above E10 to prevent engine damage.
To adjust the track tension, elevate the rear of the snowmobile and measure the sag at the midpoint of the track. Use the adjusters on the rear suspension to achieve the recommended tension as specified in the owner's manual.
The recommended spark plug gap for the Polaris 120 Indy is 0.028 inches. Ensure the plug is clean and properly gapped for optimal performance.
Oil changes in a Polaris 120 Indy are not necessary as it uses a 4-stroke engine with a sealed lubrication system. However, always verify the lubrication system is functioning correctly and check the oil level periodically.
If the headlight is not working, check the bulb to see if it is burnt out. Inspect the headlight wiring and connectors for any damage or corrosion. Also, check the fuse and replace it if necessary.
For off-season storage, clean the snowmobile thoroughly and dry it. Add a fuel stabilizer to a full tank and run the engine for a few minutes. Elevate the snowmobile to relieve pressure on the suspension and track. Store it in a dry, covered area.
Always wear a helmet and appropriate protective gear. Ensure children are supervised and understand the controls. Operate at safe speeds and avoid riding on thin ice or in restricted areas. Regularly inspect the snowmobile for any mechanical issues.
