Why is my Polaris Outlaw 525 IRS engine pinging or knocking?

If your Polaris Offroad Vehicle engine is pinging or knocking, it could be due to poor quality or low octane fuel; replace it with recommended fuel. Also, incorrect spark plug gap or heat range can cause this, so set the gap to specifications or replace the plugs.
