Motorcycle spark plug maintenance

Spark plugs are key components of motorcycle engines. The normal combustion of the mixture is the key to the normal operation of the engine. First of all, the types of spark plugs used in each engine are different, mainly due to different calorific value, thread size, etc., so be sure to use the specified type of spark plug. The engine is burning normally. Unscrew the spark plug and observe that the electrode should be ochre red normally. If it turns black, there is carbon deposition, indicating that the mixture is too rich and the combustion is not sufficient. The carbon deposition should be cleaned up. Use a sharp cone to clean the carbon deposits on the central electrode groove and L pole; adjust the spark plug gap: GS125 (0.6-0.9mm), QS150T (0.7-0.8mm), carbon deposits on the spark plug will prevent good sparks and may cause misfires ;If it is found that the spark plug is easy to be wet or burnt to gray, indicating that the heat value of the spark plug does not match, you should go to the designated repair shop of Qingqi Suzuki to replace the suitable spark plug. Note:

1. Determine the thread size and plug stem length. If the plug rod is too short, it will cause carbon deposits on the threaded portion of the plug hole and cause damage to the engine.

2. Before applying the spark plug wrench, carefully screw the spark plug into the threaded part of the cylinder head by hand to prevent damage.

3. Tighten the spark plug to the specified tightening torque using the spark plug sleeve of the special vehicle-mounted tool.
