Do you know how to choose spark plugs for off-road motorcycles?

The spark plug is a "lighter" that ignites the mixed gas. Its working conditions are very harsh. It needs to withstand the high voltage of 20,000 to 30,000 volts, the repeated impact of high-pressure gas of 50Kg/cm2, the change of temperature difference from room temperature to 2500°C, and the corrosion of combustion products. Spark plugs are vulnerable and consumable parts of motorcycles, which need to be checked and replaced regularly. Under normal circumstances, they need to be checked every 1000-3000Km and replaced every 10000Km. For this reason, motorcycle drivers must deal with spark plugs, and need to master some basic knowledge of spark plugs.

When the calorific value of the spark plug is selected incorrectly, it will cause engine failure. If a cold-type spark plug is used for a low-temperature engine, a small amount of carbon deposits will occur on the electrode of the spark plug, which will cause the electrode to short circuit quickly, resulting in ignition failure. If the engine with lower temperature uses a hot spark plug, the heat of the spark plug will not be conducted in, so that the temperature of the electrode will rise very high, which will cause spontaneous combustion, resulting in disordered ignition of the engine and a decrease in power.

The spark plug is a consumable part on the motorcycle. When the ignition is abnormal, the first thing to consider is whether the spark plug has been maintained and replaced. What kind of spark plugs to replace and how to replace each other? It is necessary to clarify the meaning of the codes specified by motorcycle spark plugs. Now take the T4135 spark plug as an example, in which T means that the model is a standard type, and if there is no letter, it is a general type. The number means that the diameter of the thread is M14. The number 13 means that the length of the screw thread is 13MM. It can be seen from the above that as long as the spark plugs with the same thread diameter and the same thread length can be installed on the engine, but the effect of its calorific value should also be paid attention to.
