What causes a Polaris Utility Vehicle engine to backfire?
- JJasmine MosesJul 28, 2025
If the engine of your Polaris Utility Vehicle is backfiring, begin by inspecting, cleaning, and/or replacing the spark plug if it shows signs of weakness. Check the spark plug gap and heat range, setting the gap to the correct specifications or replacing the plug if necessary. If you're using old or non-recommended fuel, replace it with fresh, recommended fuel. For incorrectly installed spark plug wires, incorrect ignition timing, or mechanical failure, consult your Polaris dealer. Also, check all ignition connections and tighten any that are loose. If water is present in the fuel, replace it with fresh, recommended fuel.
