What causes oil leakage after a motorcycle falls over?

[StBradley]

There are several situations where oil leakage occurs after a motorcycle falls over: carburetor leakage and fuel spilling from the fuel tank. Methods to handle motorcycle oil leakage: First, clean the motorcycle's engine, then use aluminum repair agent to patch the leaking area. If this does not resolve the issue, it should be promptly sent to a repair workshop for maintenance. Reasons for carburetor leakage: In a motorcycle carburetor, the float chamber normally maintains a constant liquid level. If the vehicle falls, the liquid level will rise, causing fuel to flow out through the carburetor's return pipe. Carburetor motorcycles rely on gravity for fuel supply. The float in the float chamber is connected to a switch that controls the amount of gasoline entering the carburetor. If the switch fails, gasoline will continuously enter the carburetor under gravity, flowing into the engine intake and air filter. Therefore, an overflow pipe is designed to discharge excess gasoline through the pipe below the carburetor when the float switch fails to close. Fuel spilling from the fuel tank: This phenomenon usually occurs on motorcycles that have had their fuel tank cap replaced. If it is the original cap, only a small amount will leak out because the fuel tank cap has an exhaust hole.
