I was wondering if someone would please tell me what length of chain I need, I just bought a rear sprocket that was 2 teeth sizes bigger, I want to go from the stock 50 to a 52, I thought I might be able to make it fit, but it isn't even close, and I can't get the rear tire on. They sell the chains in all different length but I don't know what the stock length is. I guess I could count the links but I was hoping for a little help. Any would be appreciated.
