Why won't the motorcycle start after refueling when it ran out of gas?

Motorcycle failing to start after refueling when it ran out of gas may be due to spark plug failure, and users can resolve this by replacing the spark plug. If the spark plug appears blackened and charred, it indicates that the spark plug has burned out, and a new one should be installed. If no blackening is observed, check if the spark plug is dry. If it is dry, it means no fuel is reaching it; if it is wet, then it is functioning normally. Relevant information about spark plugs is as follows: Introduction: The spark plug is a crucial component of the ignition system in a gasoline engine. It introduces high voltage into the combustion chamber and generates a spark across the electrode gap, igniting the combustible mixture in the cylinder. It primarily consists of a terminal nut, insulator, terminal post, center electrode, side electrode, and shell, with the side electrode welded to the shell. Working Principle: Under high voltage, the air between the center electrode and the side electrode of the spark plug 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.
