We focus on the production of various types of motorcycle accessories, from tiny parts to large and heavy parts that can be purchased and used.

When the engine is running in a vehicle, some abnormal noises of piston knocking occur, and the position of abnormal piston knocking is at the upper part of the cylinder.

The following methods can be used to deal with piston knocking:

(1) When the engine temperature is normal, there will be an obvious knocking sound. High-speed operation should be avoided as much as possible, and the engine should be disassembled and repaired as soon as possible.

(2) After removing the cylinder head and pulling out the piston, it is found that the cylinder is seriously out of round, strained, or the gap between the piston and the cylinder is too large. Replace the cylinder liner, piston and piston ring.

(3) If the connecting rod is found to be deformed, it should be replaced as much as possible.
