What Causes a Motorcycle to Fail to Start After Falling Over?

[HarrisonLynn]

Motorcycle failing to start after falling over could be due to gasoline flooding the cylinder and wetting the spark plug, gasoline entering the air filter causing blockage, or even engine oil entering the air filter or carburetor through the breather tube, leading to failure to start. Below is an introduction to motorcycle spark plugs: 1. Introduction: The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high voltage into the combustion chamber and generates a spark across the electrode gap to ignite the combustible mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. 2. Working Principle: Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties.
