1. What is a pulling cylinder?

"Cylinder pulling" is a very common fault that occurs during the use of motorcycles. Please note that it is a very common fault. This kind of malfunction is mainly manifested as the adhesion between the inner wall of the cylinder block and the piston, which causes burrs to appear on the originally extremely smooth working surface. As a result, it will lead to adverse reactions such as air leakage, oil burning, power reduction and increased fuel consumption in the internal combustion engine.

The main causes of motorcycle "cylinder pulling" include high temperature and incomplete lubrication. In special circumstances, it may also be caused by damage to internal engine parts.

Therefore, the probability of motorcycle cylinder pulling is higher in summer, so it is not inappropriate to call summer a high-incidence period for such faults. But in fact, the cold winter can also cause engine cylinder pulling. As mentioned earlier, the main causes of cylinder pulling include not only high temperature but also poor lubrication. In winter, due to the poor fluidity of engine oil at low temperatures, cylinder pulling faults are also very likely to occur.

2. Causes of cylinder pulling

The causes of motorcycle cylinder pulling, apart from high temperatures, poor lubrication and component damage, are actually directly related to improper use and unreasonable maintenance. For instance, prolonged violent riding at high RPMS will increase the possibility of engine cylinder pulling. In addition, adding low-quality engine oil will definitely cause cylinder pulling. This is because the high-temperature adhesion and lubrication effect of such products are almost zero. It's the same as dropping a few drops of water on a teppanyaki grill, which can't achieve the effect of lubricating the cylinder wall at all. All of this belongs to human factors.

If further detailed, the causes of motorcycle cylinder pulling also include mechanical reasons such as low oil level, clogged filter, and blocked oil passage. All of them will cause faults in the originally perfect lubrication closed loop.

3. How to avoid cylinder pulling?

Once the cause of the cylinder pulling is identified, looking for a solution will become very clear, understandable and straightforward. To reduce the probability of a motorcycle engine being pulled, it is necessary to develop good driving habits, which are specifically manifested as:

A. Regular inspection: Many friends do not check the oil level within A cycle after maintenance, but in fact, this is wrong. It is very necessary for us to regularly observe the oil level of the lubricating oil and keep it always between the upper and lower marks, because over 80% of the causes of cylinder pulling are due to the lack of lubricating oil.

B. Choosing oil products, choosing lubricating oil is not a mystery. It doesn't have to be expensive, but it must be right. The structure and characteristics of each motorcycle engine are different. An expensive one may not be suitable for your model. Therefore, in addition to choosing genuine lubricating oil, we should also fully consider the vehicle's usage environment to ensure that the current oil can protect the engine. Otherwise, it would be better not to change it.

C. Avoid high temperatures. In summer, as the ambient temperature is already high, if you ride at high speed for a long time, it will inevitably increase the burden on the engine. Therefore, maintaining a reasonable speed while riding and taking appropriate breaks are also important measures to prevent engine cylinder pulling. At the same time, it is necessary to ensure that the cooling system operates at 100%. If there are any issues such as insufficient coolant, the fan not rotating, or the heat sink being too dirty, they should be dealt with promptly.

D. Clean the oil passage. Here, cleaning the oil passage mainly refers to the oil filter or filter screen. As long as they are not damaged and the oil quality is up to standard, the possibility of internal oil passage blockage in the engine is relatively small.

However, if the oil filter screen or filter is not replaced or cleaned regularly, or installed in reverse, it will be troublesome. Therefore, it is particularly important to clean or replace it regularly.

E. Startup preheating: This topic is often scoffed at by some so-called experienced drivers, but in fact, the preheating during the first start of a motorcycle is quite important. It can thoroughly lubricate all the key parts of the engine in the shortest time, including the bearing shells, piston rings, inner walls of the cylinder block, camshafts, rocker arms, small chains and other important components.

In conclusion, based on the feedback from the maintenance market and the analysis of user faults, excluding the quality issues of some vehicles themselves, the majority of motorcycle cylinder pulling faults are related to human factors such as improper operation, poor fuel quality, and unreasonable maintenance.
