So if you saw my post about my bike, I replied how it had a large crack in the head piece. Well I fiberglassed it and am almost done painting it, so my bike is almost back together! Also, I ordered a 28 tooth racing sprocket from pbu. Will this be hard to install? I am not going to install it until I get the chain and front sprocket but I am going to keep it because I could only partial order at this time. Thanks!
