What are the reasons why a motorcycle won't start after a fall?

[AshlynLynn]

The reasons why a motorcycle won't start after a fall are gasoline entering the air filter and no fuel in the carburetor. Below are detailed explanations and solutions: Gasoline entering the air filter: This can soak the filter element, causing it to block airflow. You can remove the air filter element to check if it's soaked with oil, remove the spark plug, and use the kick starter or electric starter to crank the engine several times to expel the gasoline from the cylinder. Then, reinstall the spark plug and try starting the engine. No fuel in the carburetor: Since scooters use a vacuum-operated fuel valve, the fuel tank won't supply fuel when the engine is not running. After a fall, the gasoline in the carburetor may drain out, causing the engine not to start, and the fuel tank won't supply fuel when the engine isn't starting. You can first turn off the ignition key, kick start several times, then turn the key to start, or use the electric starter for a while to draw fuel into the carburetor.
