My bike wears chains out quickly. There's a lot of chain noise as well. My rear sprocket does not line up exactly square but its not off much. The instructions that came with the motor mentioned rounding off the drive sprocket due to some quality control issues? Has anyone done this? Will it make a differance. I can see that the wear is caused when the chain enters the sprocket. I hate changing out chains every couple of hundred miles.
