How to maintain the motorcycle?

Motorcycle maintenance mainly includes three aspects:

First, the maintenance of spark plugs

Spark plug is a key component of motorcycle engine. The normal combustion of the mixture is the key to the normal operation of the engine.

Precautions:

1. Determine the thread size and stopper length. If the plug rod is too short, it will cause carbon deposition on the thread of the plug hole and damage the engine.

2. Before using 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 by using the special vehicle-mounted tool spark plug sleeve.

Second, the maintenance of air filter

1. Remove the air cleaner element from the vehicle.

If the filter element is sponge foam, it can be carefully cleaned with neutral washing liquid, and do not twist it hard.

Dry the water after cleaning, drop 2-3 drops of engine oil (in order to absorb tiny dust in the air), hold it evenly with your hands and put it back in its original place as it is; If it is a paper filter element, it must not be cleaned with liquid, but the dust inside can be knocked hard, and if possible, compressed gas can be blown in the opposite direction of air intake (it must not be blown back, otherwise the dust will be blown into the pores of the paper core, making the blockage more serious).

2. When replacing the filter element, pay attention to the installation direction and air intake direction.

When driving in dusty and dirty environment, the cleaning frequency should be increased. If it is found that the sponge is broken or the paper filter element is soaked, it should be replaced immediately, otherwise it will damage the engine or emit black smoke.

Three. Maintenance of oil filter element

In the process of engine lubrication, the oil pump sucks the oil out of the bottom groove, first presses it into the oil filter element for filtration, and then delivers the filtered clean oil to the cylinder head, crankshaft and transmission parts. If the filter element is too dirty, the oil filtering effect is poor, the oil output is reduced, and the lubrication of various parts is not good, which will cause excessive wear. Therefore, it is unacceptable to only replace the engine oil, and the engine oil filter must be replaced at the same time.

Precautions:

1, frequent oil change

Generally, motorcycle oil should be changed every 500 kilometers during the running-in period, and every 2000 kilometers after the running-in period 1500 kilometers, which is better for the car.

2. Clean the filter frequently.

At present, most motorcycles in China use sponge filter elements. It is best to coat the surface with a layer of engine oil after cleaning, which can enhance the filtering effect.

3, adjust the parts

The tightness of chains, front and rear axles, directional axles and other screws should be adjusted regularly.

4. Listen, look and identify the quality of the car.

Listen; If the engine suddenly hears abnormal noise, it is usually that component is broken or stuck. Don't start the car now. Be sure to find a professional to repair in time. If there is noise for a long time, a part must be worn or loose and must be replaced.
