4. No Fuel

Draining Carburetor

File this one under, Duh. Just like when an object can often not be where your are certain you left it, check to see if there is fuel in the tank. Shake your bike back-and-forth while listening for the telltale slosh. Although it was always funny when Wile E. Coyote checked the tank with a match, use your smart phone’s flashlight instead. Once you’ve made sure you have fuel, check to see if the fuel pump is running on bikes that have them. Also, on carbureted bikes, open the float bowl drain to see if any of the gasoline from the tank is making it to the carburetors.
