ok worst case scenerio: I'm riding my bike an since i don't race i haven't looked at my top-end latley and i don't realize that my rings are worn their limit. Any ways i'm riding and my piston seizes and the rings scrath up the cylinder badly. Since my bike is over bored can i just buy a new sleeve for my bike and put that in the cylinder and change the top-end and be fine? or do you need to do something to the cyllinder, like send it out to eric gorr? I know it may be cheaper to send it somewhere but could you just buy a new sleeeve every time your bike did this? any help would be greatly appreciated. :think:
