What to do if my Polaris Offroad Vehicle engine runs irregularly, stalls, or misfires?

If your Polaris Offroad Vehicle engine runs irregularly, stalls, or misfires, it could be due to several reasons: fouled or defective spark plugs (inspect, clean, or replace the spark plugs), worn or defective spark plug wires (see your dealer), incorrect spark plug gap or heat range (set gap to specs or replace plugs), loose ignition connections (check all connections and tighten), water present in fuel (replace with new fuel), low battery voltage (recharge battery to 12.8 VDC), a kinked or plugged fuel tank vent line (inspect and replace), incorrect fuel (replace with recommended fuel), a clogged air filter (inspect and clean or replace), or other mechanical failure (see your dealer).
