When starting with a heavy load, the oil clutch does not cooperate well, so the chain of the motorcycle will loosen. Make timely adjustments to keep the tightness of the motorcycle chain at 15mm to 20mm. Check the buffer bearing frequently and add grease on time. Because the bearing has a harsh working environment, once it loses lubrication, the damage may be great. Once the bearing is damaged, , It will cause the rear chainring to tilt, which will wear the side of the chainring chain if it is light, and will easily cause the chain to fall off if it is severe.
After the chain adjustment scale is adjusted, use your eyes to observe whether the front and rear chainrings and the chain are on the same straight line, because if the frame or rear fork has been damaged.
After the frame or rear fork is damaged and deformed, adjusting the chain according to its scale will lead to a misunderstanding, mistakenly thinking that the chainrings are on the same straight line. In fact, the linearity has been destroyed, so this inspection is very important (it is best to adjust it when Remove the chain box), if any problem is found, it should be corrected immediately to avoid future troubles and ensure nothing goes wrong.
Extended information
When replacing the chainring, you must pay attention to replacing it with high-quality products made of good materials and fine craftsmanship (generally the accessories from special repair stations are more formal), which can extend its service life. Don’t be greedy for cheap and buy substandard products, especially substandard chainrings. There are many eccentric and out-of-center products. Once purchased and replaced, you will find that the chain is suddenly tight and loose, and the consequences are unpredictable.
Frequently check the matching clearance between the rear fork buffer rubber sleeve, the wheel fork and the wheel fork shaft, because this requires strict lateral clearance between the rear fork and the frame, and flexible up and down movement. Only in this way can the rear fork and the vehicle be ensured. The frame can be formed into one body without affecting the shock-absorbing effect of the rear shock-absorbing. The connection between the rear fork and the frame is realized through the fork shaft, and it is also equipped with a buffer rubber sleeve. Since the quality of domestic buffer rubber sleeve products is not very stable at present, it is particularly prone to looseness.
Once the joint part becomes loose, the rear wheel will be displaced under the restraint of the chain when the motorcycle starts or accelerates. The size of the displacement is determined by the degree of damage to the buffer rubber sleeve. At the same time, there is a clear sense of shaking of the rear wheel when accelerating and decelerating. This is also one of the important reasons for chain gear damage. More inspection and attention should be given.
