Spark plug maintenance

Spark plug is the key component of motorcycle engine. The proper combustion of the mixture is the key to the normal operation of the engine. First of all, the type of spark plug used by each engine is different, mainly the heat value, thread size and so on, so must use the specified type of spark plug.

The engine burns normally, unscrew the spark plug observation, the electrode should be red ochre normally, if black, that is, there is carbon, indicating that the mixture is too strong, combustion is not sufficient, should clean up the carbon. Use a sharp cone to clean the central electrode groove and L pole carbon deposit; Adjust the spark plug gap: GS125 (0.6-0.9mm), QS150T (0.7-0.8mm), carbon on the spark plug will hinder good spark, and may lead to broken fire; If it is found that the spark plug is easy to wet or burned gray, indicating that the spark plug heat value does not match, it should go to the Suzuki designated repair shop to replace the appropriate spark plug.


1. Determine thread size and plug rod length. If the plug rod is too short, it will cause carbon accumulation in the thread part of the plug hole and damage the engine.

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

3. Use the spark plug sleeve of special vehicle tools to tighten the spark plug to the specified fastening torque.


The air filter is the respiratory system of the motorcycle. If the air filter is blocked by dust, the intake resistance will increase, the engine output power will decrease, the fuel consumption will increase, the engine will be difficult to start, easy to stall, serious dust into the cylinder block, will aggravate the wear and tear of the engine components.

Clean the air filter according to the following steps:

1. Remove the air filter element from the car; If the filter element is sponge foam, the neutral washing liquid can be carefully cleaned, do not twist hard, after cleaning to dry water, drop 2-3 drops of oil (in order to absorb very fine dust in the air), with the hand, according to the original state; If it is a paper filter element, it must not be cleaned with liquid, it can be hard to knock the internal dust, and if there are conditions, compressed gas can be blown in the opposite direction of the intake (do not reverse, otherwise the dust will be blown into the pores of the paper core will be blocked more)

2. Pay attention to the installation direction and intake direction when installing the filter element; Driving in a dusty and dirty environment should increase the cleaning frequency. If it is found that the sponge is broken or the paper filter element is soaked, the new product should be replaced immediately, otherwise it will damage the engine or take black smoke.
