1. Motorcycle Chain and Sprocket manufacturers tell you that the tightness of the sprocket should be appropriate. Too tight will increase power consumption and the bearing will be easily worn; if the sprocket is too loose, it will be easy to jump and fall off the chain. The tightness of the sprocket is: lift or press down from the middle of the sprocket, which is about 2%-3% of the center distance of the two sprockets.

2. Motorcycle Chain and Sprocket manufacturers tell you that the sprocket should be installed on the shaft without swing and skew. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprockets is less than 0.5 meters, the deviation can be 1 mm; when the center distance of the sprockets is more than 0.5 meters, the deviation can be 2 mm. However, there should be no friction on the side of the sprocket teeth. If the offset of the two wheels is too large, it will easily cause off-chain and accelerated wear. Care must be taken to check and adjust the offset when replacing sprockets.
3. Motorcycle Chain and Sprocket manufacturers tell you that after the sprocket is severely worn, you should replace the new sprocket and the new sprocket at the same time to ensure good meshing. We can't just replace a new sprocket or a new sprocket alone. Otherwise, it will cause poor meshing and accelerate the wear of the new sprocket or the new sprocket. After the sprocket tooth surface is worn to a certain extent, it should be turned over and used in time (referring to the sprocket used on the adjustable surface) to prolong the use time.
The above information is Motorcycle Chain and Sprocket Manufacturer's introduction and analysis of the maintenance and maintenance of the sprocket, hope it helps you.
