Was up busa world. I have a quick question. Gen 2 busa. I'm already down 1 in the front. Stretched 4 inches. Would I notice a difference if I went up +1 in the rear??
Or would that be to little to really make a difference. I'm trying to use the same chain since its practically new.
Gearing now is 17/43
