EZGO Oversize Drive Belt for GX390/Clone Engine Swaps
This drive belt is the correct size for those installing a GX340/GX390, GX420/GX440 or 460cc Clone into a EZGO TXT , Medalist, and Marathon Golf Cart.
This belt assumes you are using your factory Starter/Gen to "Pedal Start" your engine. If using the onboard electric starter and idling your engine (NOT RECOMMENDED), you must use the belt intended for V-Twin Swaps because the belt must be significantly more loose to shift gears while the engine is running:
