How to extend the service life of the

motorcycle

Every motorcycle rider hopes the service life of his motorcycle will be as long as possible. The

service life of the motorcycle is calculated according to its overhaul mileage, which is

generally between 50,000 km and 100,000 km, with reasonable use, your motorcycle may

be used for a period of the upper limit while with unreasonable use, it may fail to reach the

lower limit. Thus, it can be seen that how to use motorcycle has a great influence on its service

life.

When the surface of the cylinder and crankshaft is worn, especially wear on the surface of the

cylinder, the motorcycle need to be overhauled. Because the wear and tear will increase the

clearance between the piston and cylinder, then cause leaking, the fuel consumption of

motorcycle will rise sharply and the mechanical efficiency will fell sharply. How to avoid wear

and tear on the surface of the cylinder becomes the key to extend the service life of

motorcycle. Here we will discuss about the methods to avoid wear and tear on cylinder.

Good running-infor new motorcycle

The surface of cylinder is uneven since it is left the factory, so the convex part is easy to get

damaged. If there is a heavy load, it will cause scratch on the surface of cylinder. When driving

the new motorcycle, you should better avoid heavy load. Only after the convex part is grinded

to be smooth enough, can the cylinder bear bigger load, which will extend the service life of

cylinder. Manufacturers require motorcycle rider to do a good running-in for a new motorcycle,

usually in the period of 1000 to 2000 kilometers. In running-in period, it is better not to carry a

passenger or goods. For two-stroke motorcycle, the mixing ratio of fuel and oil should be

increased to 20:1 so as to benefit the running in of the cylinder.

Cleanedair into the cylinder

You need to make sure the air is clean enough before it enters into the cylinder, if there is too

much dust inside the air, it will speed up the wear and tear of the cylinder. It is better to remove

dirt inside the air filter regularly, around every 1000 km, besides, you should also check the

sealing at each joint of the filter, so as to avoid unclean air enter into the cylinder directly. In

order to improve the filtration effect, you canput a layer of foam sponge outside the paper core.

Foam sponge must be cleaned once a day in order to avoid blocking.

Good lubricationon the surface of cylinder

The wear and tear will be less if there is lubrication. This requires lubrication with a proper

viscosity. The viscosity is related to temperature so different viscosity of lubricating oil should

be used in different seasons.

In addition, you should also check oil pressure and oil scale frequently and don’t start

motorcycle when there is no lubricating oil.
