Important Mixing Guidelines

  • Always check your owner's manual for the correct oil-to-fuel ratio.
  • The right mix helps protect your engine and reduce wear.
  • Changing the ratio may require adjustments to carburetor or fuel injection settings.

Best Practices

  • Mix only what you need for the day's ride.
  • Shake or stir the fuel container before filling your tank.
  • Check spark plugs often; a fouled plug can indicate a mix issue.
