How to fix a Funbikes Offroad Vehicle that doesn't start?

W
Wendy LesterAug 2, 2025
If your Funbikes Offroad Vehicle's engine won't start, several factors could be at play. The fuel system (tubes, fuel tank, valve) might be blocked, requiring you to clean the system. Another reason could be that no current is arriving at the spark plug; in this case, try cleaning or replacing the spark plug. If the problem persists after these steps, it is recommended to consult an Authorized Dealer. Also, the engine might be flooded. If this is the case, fully open the gas and continue trying to start the engine for a few moments. If it still doesn’t start, remove the spark plug and dry it off.
