Why is my Polaris Sportsman 570 EPS Offroad Vehicle engine pinging or knocking?

If your Polaris Offroad Vehicle engine pings or knocks, it could be due to poor quality or low octane fuel. Replace with recommended fuel. Ensure that the spark plug gap and heat range are correct; set the gap to specifications or replace the plugs if necessary.
