What is the torque for a motorcycle spark plug?

[SebastianFitz]

Generally, the tightening torque for a motorcycle spark plug is 20N/m. Spark plugs of different sizes require different tightening forces. Spark plug maintenance precautions: Always keep the spark plug insulator clean and dry. During normal use, dust, oil, and other deposits may accumulate on the spark plug insulator. These deposits can form external leakage paths, affecting the normal sparking of the plug. When servicing the engine or performing other operations, avoid hitting the spark plug insulator to prevent damage due to force, which could affect its normal operation. When connecting or disconnecting the high-voltage wire, be careful and gentle. Avoid excessive force or shaking the spark plug insulator, as this may compromise the seal or damage the spark plug. New spark plugs or those removed for cleaning and inspection should not be dropped or thrown, as this may damage the insulator.
