What is the reason why the motorcycle cannot start after refueling when it runs out of gas?

Motorcycle cannot start after refueling when it runs out of gas due to spark plug failure, the user can replace the spark plug. Spark plug gap: The gap between the spark plug electrodes has a significant impact on the performance of the spark plug. If the gap is too small, the spark will be weak and prone to carbon buildup and leakage. If the gap is too large, the required breakdown voltage increases, making the engine harder to start, and it is more likely to experience "misfiring" at high speeds. Therefore, the spark plug gap should be appropriate. Generally, the spark plug gap for battery ignition systems is 0.7 to 0.8mm, with some spark plugs having gaps up to 1.0mm or more. Spark plug heat value: The standard for spark plugs often uses heat value to characterize the thermal properties of the spark plug. The heat value of a spark plug indicates the balance between heat absorption and dissipation of the spark plug insulator skirt. The higher the heat value, the stronger the balance between heat absorption and dissipation. Thus, hot-type spark plugs have lower heat values, while cold-type spark plugs have higher heat values. Generally, high-power, high-compression engines use cold-type spark plugs with high heat values; conversely, low-power, low-compression engines use hot-type spark plugs with low heat values.
