Default Re: Bought bottom end from Boy Go Fast, should I be worried?

Well thanks map bike, but I already got the bottom end from bgf in the mail today. Looks nice, has a big front mount and I don't know if this matters but the piston does measure 1 1/16, not 15/16. I am going to put it on tomorrow and see how it pulls. I asked bgf again about stroke size, and he said 40mm. However, I really do not trust him on that one.
