  If your Polaris Offroad Vehicle engine stops or loses power, begin by refueling if the tank is empty, cycling the key to the ON position three times for 5 seconds each, then attempt to start. Inspect and replace the fuel vent line if it's kinked or plugged. If there's water in the fuel, replace it with new fuel. Inspect, clean, and/or replace the spark plug if it's fouled or defective, and ensure the spark plug gap is set to specifications, replacing the plug if necessary. Check and tighten any loose ignition connections. Recharge the battery to 12.8 VDC if the voltage is low. Replace the fuel with fresh, recommended fuel if incorrect fuel is used. Inspect and clean or replace the air filter if it's clogged.
