What should be in the cylinder of a motorcycle and some questions

The normal cylinder should not have a little scratch, change the cylinder and change the piston this depends on your use of the layer, generally speaking, if it is not broken oil and pull the cylinder, the piston will generally not have a problem, the piston ring must be replaced after the cylinder is changed, as for the valve, it also depends on the state, if it is directly worn, the edge becomes the knife edge to be replaced, if there is only a little carbon deposit, just grind on the line, the valve is also worn, and it is normal for the natural grinding to be damaged. The rear wheels can shake from side to side, and if it is a gap between the rear wheels and the engine, it can be solved by simply adding a pad to eliminate the gap after tightening the wire. If it is the gap between the engine and the frame drop, the center sleeve needs to be replaced.

**This is not easy to say, each place** is different, the general cylinder, piston, piston ring for you to change all about 200 yuan. Hope it helps.

Hello, the motorcycle needs the same cartridge period as the new car after the cylinder change, and the problem should be better after the cartridge period, as for the taste, 1, check whether the exhaust pipe has oil, 2 check whether the oil is burned. 3. The oil of the new cylinder can't go up, and it can't play a lubricating role 29189, I hope it will help you!

Don't worry, the accessories are now very mediocre. However, the cylinder does not have to change the piston, and the piston ring is generally replaced after disassembly. As for your valves, they burned out because they were not lubricated by oil.

The part with a heat sink on the outside is.

There are many kinds of motorcycle engines, and there may be a variety of parts above and behind their cylinders, as well as different models such as vertical cylinder engines, horizontal cylinder engines, single-cylinder engines, multi-cylinder engine flush stoves, etc., and the parts "behind" of their cylinder blocks are also different. In the case of grip judgment without ** instructions, it is impossible to determine what kind of part it is.

For example, behind the motorcycle engine block, it can be the box of the engine gearbox, or the timing chain tensioner, starting motor, carburetor or throttle valve and other zero-stage broken parts.

Summary. Hello, the cylinder on the left side of the motorcycle is not working, the relevant reasons and treatment methods are as follows. The first is the ignition coil of the vehicle, or the phenomenon caused by the spark plug is a problem, and the ignition coil and spark plug need to be checked.

The second is that there is a problem with the fuel injector of the vehicle, which causes this phenomenon and needs to check the fuel injector. The third is the electric phenomenon caused by insufficient cylinder pressure in the vehicle engine, which needs to be replaced with four sets.

The third is the electric phenomenon caused by insufficient cylinder pressure of the vehicle engine, which needs to be replaced by four macro guess round matching.

The two exhausts of the parallel bars are hot, but he makes the sound of the horizontal bars.

What's the problem.

This is obviously a lack of cylinders, and the vehicle engine does not work.

That's how to fix it.

What is basically needed to be replaced.

The aspects I just mentioned should be checked and ruled out.

Summary. The left cylinder of the two-cylinder motorcycle does not work, and there may be many kinds of faults, in addition to pulling the cylinder, others such as the left carburetor or EFI valve body is faulty, the left cylinder is leaking, the left cylinder has a problem with high voltage, and the left cylinder is not well exhausted, etc., which will also cause a cylinder of the two-cylinder car to not work, and it needs to be checked in many aspects.

In addition to pulling the cylinder, others such as the left carburetor state return or EFI valve body is faulty, the left cylinder leaks, the left cylinder has a problem with high voltage, the left cylinder exhaust is not smooth, etc., these will also cause a cylinder of the two-cylinder car to not work, and it needs to be checked in many aspects.

The carburetor was new, with only one igniter.

This problem is very simple, because you have just changed the carburetor, maybe the gap in the oil needle inside the carburetor is too small, resulting in insufficient oil supply. When running at low speed, the carburetor can ensure the normal operation of the engine, but if you want to run at high speed, the fuel supply is insufficient, or the accelerator god regrets that it will turn off when it is increased. You can disassemble the oil needle and adjust the snap ring of the oil needle up by a small grid.

The throttle adds up to not burn.

The following are the specific manifestations of motorcycle cylinder damage:

Engine cylinder head leaking:

The seal between the cylinder head and the cylinder block is not tight, which eventually leads to leakage of sock gas. Due to the leakage of oil and water, the place where the leak is also accompanied by the splashing of oil and water, and at the same time, there is a splashing sound of gas-doped liquid.

Cylinder decompression: The compressed gas in the cylinder will leak out of the gap, or leak the gas or rush to other cylinders. Eventually, the engine was running unstable.

Oil and water leaks:

Under the action of water pump and oil pump, the coolant and oil generate a certain delivery pressure. If the cylinder head gasket is damaged, it will cause leakage or even channeling between the coolant and oil, which will lead to deterioration of the coolant and oil.

Gases enter oil and water channels:

When high-pressure gas enters the oil or water channel, it will affect the heat dissipation and lubrication of the engine, resulting in a large increase in engine temperature and aggravating the wear of engine parts. At the same time, a large number of bubbles can be seen in the expansion kettle.

Generally speaking, for the engine, there are three parts of the thermal part of the four-stroke engine, which are called the cylinder head, the front cylinder head, or the cylinder (also known as: middle cylinder) from top to bottom.

The function of the middle cylinder is simply the running rail of the piston, and at the same time, it is a closed container (a confined space composed of the cylinder head) for fuel to generate power.
