11.2 - If The Engine Quits or Not Start
If the engine was not making unusual noises before it quit running, and it feels normal when you operate the kick starter, you can probably rule out a major mechanical problem.
First, check the fuel system:
- Make sure you have fuel in the gas tank and the fuel valve is set to the “ON” position.
- Check the fuel tank cap breather hose to be sure it is not pinched or clogged.
- Turn the fuel valve to the “OFF” position. Disconnect the fuel line from the carburetor and momentarily turn the fuel valve to “ON”. If fuel does not flow out, there is an obstruction in the fuel tank, fuel filter, or in the fuel line.
If the fuel system appears to be okay, check the ignition system.
- Check the spark plug cap. Be sure that it is not loose or disconnected.
- Disconnect the spark plug cap and remove the spark plug. Connect the spark plug to the plug cap and place the threaded end of the spark plug on a metal part of the engine.
- Kick the kick starter while you watch the spark plug. If it sparks, the ignition system is probably working. If there is no spark, replace the spark plug with a new one. If there is still no spark, there is a problem with the ignition system.
If you cannot identify or correct a problem, you will have to push your motorcycle back to your base or get some help.
