  If your Polaris Offroad Vehicle engine turns over but doesn't start, several factors could be the cause. First, ensure you have fuel by turning the fuel valve to reserve and refueling if necessary. Check for a clogged fuel valve, and clean or replace it if needed. Drain the fuel system and refuel if water is present in the fuel. Make sure the fuel valve is turned on and that you're using new, recommended fuel. Inspect the spark plug for fouling or defects, replacing it if necessary, and verify the stop switch is on. Also, check the battery voltage and recharge to 12.8 VDC if low. Adjust throttle freeplay in case of throttle ETC switch malfunction. If the problem persists, it may be a mechanical failure, and you should seek assistance from your Polaris dealer.

  Irregular engine performance in your Polaris Offroad Vehicle can stem from several causes. Start by inspecting the spark plug for fouling or defects, and clean or replace it if necessary; also check the spark plug gap or heat range and set gap to specs or replace plugs. Check all ignition connections and tighten any loose ones. Replace the fuel if water is present or if it's old, poor, or non-recommended. Inspect and clean or replace a clogged air filter. Ensure the fuel tank vent line isn't kinked or plugged. Recharge or replace the battery if the voltage is low (12.8 VDC). For worn or defective spark plug wire, electronic throttle control malfunction, or other mechanical failure, consult your Polaris dealer.
