Antwoord op "What do I do if the motorbike does not stay on?"It could be a battery, electrical or a fuel problem. First. Hook up a volt meter to the battery and check the voltage. It should be around 12.5 volts. Then try cranking it, it should drop a little, if it drops considerably, like down to 8 volts, you should charge the battery. Next, try spraying some starter fluid into the carb and see if it starts, it will likely cut back off shortly. If it does, that confirms a fuel issue — but it could be anything from the fuel filter to a clogged carb. Electrical—I’m not even going to touch!
