Beyond the pre-season checkup and maintenance, you can follow these suggestions to make sure your snowmobile runs cleaner and quieter.

  • Follow the manufacturer’s recommendation for type of oil and gas. Use high-grade oil and gasoline, which burn cleaner.
  • Tune the engine for your altitude, including the proper carburetor jet setting, which improves fuel efficiency and reduces emissions.
  • Change the spark plugs at least once during the season to ensure efficient fuel burning.
  • Avoid opening and closing the throttle continuously, which causes inefficient fuel burning and increases emissions and noise.
  • Don’t tamper with your exhaust pipes, as that causes the machine to exceed legal noise limits.
