What is the reason for a motorcycle not starting after refueling when it runs out of gas?

If a motorcycle does not start after refueling when it runs out of gas, it may be due to a spark plug malfunction. The user can replace the spark plug to resolve the issue. If the spark plug appears blackened or burnt, it indicates that the spark plug has been damaged and needs to be replaced. If there is no visible blackening, check whether the spark plug is dry. If it is dry, it means no fuel is reaching the spark plug; if it is damp, the condition is normal. Here is some relevant information about spark plugs: 1. Introduction: The spark plug is a critical component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber and generates a spark across the electrode gap to ignite the combustible air-fuel 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.
