What do I do if the motorbike does not stay on?

It sounds like the gas tank is empty. Switch to the reserve tank by flipping a switch under the gas tank on the left hand side. This will give you enough gas to get to a gas station to fill up the tank. If this does not solve the issue, refer to the troubleshooting guide for additional information.

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!
