1 Answers
Motorcycle spark plug turning white reasons: It may be due to excessive carbon deposits in the cylinder, leading to valve blockage, which in turn causes the exhaust valve to overheat or the cooling device to malfunction. The quality of gasoline is relatively poor. There are some low-quality gasolines on the market now, and low-octane gasoline has very low combustion efficiency, consuming a large amount of oil. The spark plug has been used for too long, leading to wear and a decline in function. Improper installation of the spark plug, resulting in air leakage, is the main cause of the spark plug turning white. Solutions: Remove carbon deposits promptly, thoroughly clean the debris in the combustion chamber, increase the valve clearance, and ensure the exhaust valve can work properly. Check if the timing cooling device has failed. When installing the spark plug, master the strength, tighten the spark plug according to the regulations to avoid overheating, electrode melting, and device damage.
