Right, I got a new chian the other day, cut it to size, same size as the one thta was on before. Put the rear wheel on, chain on. Then went about tensioning the chain. Simple you think........No! When I have the chain nice and tight, then I notice the wheels but in stright(looking from behind off to the left, and rubbing on the booster. When the wheels in stright the chian is too loose and hits the chainstays. It moves over to the left when I adjust the left snail cam. But it never moves over to the right when I adjust the right snail cam. What can I do? live with it, take a few more links out of the chain. I hate a loose chain. Thanks!
