What is the reason for a motorcycle not starting after falling over?
2 Answers
The reason for not being able to start after falling over may be due to excessive fuel entering the cylinder when trying to start after picking it up, causing flooding and preventing startup. Relevant explanations are as follows: 1. Reason for not starting: When the motorcycle falls over, some fuel from the carburetor flows out through the vent hole, and some enters the cylinder. When picking it up, too much fuel enters the cylinder, causing flooding and preventing startup. Note that owners who do not plan to travel long distances should not fill the fuel tank completely to maintain fuel freshness and reduce vehicle weight. 2. Solution: Simply remove the spark plug, dry the fuel on the spark plug, press the electric start to spray out the fuel in the cylinder, then reinstall the spark plug to start the motorcycle.
I've been riding motorcycles for over a decade. In this situation, the first thing to check is whether the safety switch was triggered when the bike fell. Many modern motorcycles are equipped with tip-over sensors that automatically cut off fuel supply to prevent fuel leaks and potential fires. I remember last time my bike fell, I tried starting it three times without success, only to later discover the fuel line connector had come loose and gasoline was leaking. If you smell gasoline, never force-start the engine - turn off the power and wait at least half an hour first. Besides fuel system issues, loose battery terminals are most common - the impact from falling can easily shake the positive and negative terminals loose. The spark plug cap might also get clogged with dirt; just remove and clean it. Finally, check the clutch and neutral switches - some older bikes require being in neutral to start. The key is not to panic - start troubleshooting from the most obvious areas first.
