Why is my Polaris RANGER RZR XP 4 900 2013 engine backfiring?

If your Polaris Utility Vehicle engine backfires, start by refueling the vehicle. A weak spark from the spark plug could also be the issue, so inspect, clean, or replace the spark plugs. Make sure the spark plug gap and heat range are correct. Replace old or non-recommended fuel with fresh, recommended fuel. Check all ignition connections and tighten if loose. If there is water in the fuel, replace it with fresh recommended fuel. Check all exhaust connections.
