Oil and Fuel
- Check the oil level. Turn the engine off, and wait a few minutes before checking.
- Check for oil or fuel leaks.
- Check the air filter. It should be clean, undamaged, and unblocked.
- Check the spark plugs. Replace if necessary.
- Fill up the fuel tank before each ride.
- If your vehicle has a two-stroke engine that uses an oil/fuel mixture, consult your owner’s manual to find the proper oil-to-gas ratio.
