Why does my Polaris UTV 2x4 11 engine run irregularly, stall, or misfire?

If your Polaris Utility Vehicle engine runs irregularly, stalls, or misfires, several factors could be responsible. Begin by inspecting, cleaning, or replacing fouled or defective spark plugs. Set the spark plug gap to the correct specifications or replace the plugs. Check all ignition connections and tighten any loose ones. Replace fuel if water is present, or if it is incorrect, use only recommended fuel. Inspect and replace a kinked or plugged fuel vent line. Recharge the battery to 12.5 VDC if the voltage is low. Inspect and clean or replace a clogged air filter.
