1.Maintenance of spark plug

Spark plug is the key component of motorcycle engine. The proper combustion of the mixture is the key to the proper operation of the engine. First of all, the type of spark plug used in each engine is different, mainly the heat value, thread size, etc., so be sure to use the specified type of spark plug. Normal engine combustion, screw off the spark plug observation, the normal electrode should be red ochre, if black, that is, there is carbon accumulation, indicating that the mixture is too thick, combustion is not sufficient, should clean up carbon accumulation. Clean the carbon deposition of the central electrode groove and L pole with a sharp cone; Adjust the spark plug gap: GS125(0.6-0.9mm)QS150T(0.7-0.8mm). Carbon accumulation on the spark plug will hinder good spark and may cause fire break. If the spark plug is easy to be wet or burn gray, indicating that the heat value of the spark plug does not match, you should go to the designated repair shop of Suzuki Light to replace the appropriate spark plug note:

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

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

3. Use the special onboard tool spark plug sleeve to tighten the spark plug to the specified tightening torque.

Air filter maintenance

An air filter is the respiratory system of a motorcycle. If the air filter is blocked by dust, the intake resistance will become larger, will make the engine output power decline, increase fuel consumption, can make the engine more difficult to start, easy to shut off, is serious dust into the cylinder block, will exacerbate the wear of engine parts. To clean the air filter, follow the following steps:

Remove the air filter element from the vehicle;

If the filter element is sponge foam, use neutral washing liquid to wash it carefully. Do not screw hard.

After cleaning and drying the water, drop 2-3 drops of oil (to absorb very small dust in the air), shake well with your hand, and put it back in its original state; If it is a paper filter element, do not clean it with liquid, but knock the internal dust with force, if possible, blow it with compressed gas in the opposite direction according to the intake (do not reverse, otherwise the dust will be blown into the paper core pores will be more serious obstruction); Example: The QS150T paper core is blown outwards from the inside, and the storm prince is blown outwards from the outside ring to the central hole.

Pay attention to the installation direction and intake direction when installing the filter element;

When driving in a dusty and dirty environment, increase the cleaning frequency. If the sponge is broken or the paper filter element is wet, replace the new product immediately. Otherwise, the engine will be damaged or black smoke will come out.

3.Maintenance of oil filter element

Most users know that they should change the oil on time, but there is a rule to follow:

The new oil is replaced, and the filter element is not replaced. During the lubrication of the engine, the oil is extracted from the bottom tank by the engine oil pump. The oil filter is first pressed into the oil filter, and the clean oil is then transported to the cylinder head, crankshaft and transmission parts. If the filter element is too dirty, the filter effect of the oil is poor, the output of the oil is reduced, each part can not get good lubrication, will cause excessive wear, so only to change the oil is not enough, you must also change the oil filter element.
