Re: Question about 929 Chain
or the center line is not true.
If the chain is rubbing the inside of the rear sprocket (like it's trying to fly off to the outside), the rear tire center line might be going to the right of true in regards to the front tire. Try adjusting the right side adjuster so the axil moves forward on the right (brake disc side). Also, look down the chain from back to front. You will be able to see any misalignment.
REMEMBER, THE MARKS ON THE SWING ARM DO NOT ALWAYS LINE UP FROM LEFT TO RIGHT. So don't go be that.
