If your Polaris Offroad Vehicle engine is running irregularly, stalling, or misfiring, start by checking the spark plug for fouling or defects; inspect, clean, and/or replace it if necessary. Water in the fuel can also cause these issues, so replace the fuel with new fuel. Ensure your battery voltage isn't low by recharging the battery to 12.8 VDC or replacing it. Inspect the fuel vent line for kinks or blockages and replace if needed. Finally, old or non-recommended fuel can lead to these problems, so replace it with the recommended fuel.

Your Polaris Offroad Vehicle engine might stop or lose power due to several reasons. Check if you're out of fuel and, if so, turn the fuel valve to reserve and refuel. An interrupted fuel supply can also cause this issue, requiring you to clean the fuel system and carburetor. Inspect the air filter for clogs, dirt, or moisture, and clean or replace it as needed. Lastly, an overheated engine can lead to power loss, so clean the radiator screen and core (if equipped) and the engine exterior.

To prevent your Polaris Offroad Vehicle engine from overheating, first, check for debris lodged in the screen and remove it. If the radiator is plugged, use a garden hose to flush debris from the radiator fins, but avoid high-pressure washers as they can damage the fins. Ensure you have sufficient coolant, check the levels, and fill as needed, also checking for leaks. Insufficient airflow due to slow operation can cause overheating, so operate at a faster speed. Bleed the cooling system if it hasn't been already. If foam has formed in the cooling system, drain and replace the coolant with the recommended type. Finally, check for bent cooling hoses and shorten or replace them.

If your Polaris Offroad Vehicle engine fails to reach full power, the issue might stem from an interrupted fuel supply, requiring you to clean the fuel system and carburetor. Another potential cause is float leaks, in which case you should replace the float. Additionally, inspect the air filter for clogs, dirt, or moisture, and clean or replace it if necessary.
