I have a quick question. I heard that in 2004, that no overboring of any bike will be allowed in the amatuer local classes? It used to be, that you could bore your bike up to 2mm, or .080in over. But that's no longer allowed for 2004? I know that in AMA Pro, no overboring is allowed, and at other places like Loretta's and Mini-O's and such. Just wondering about the rules on the Amatuer level. Thanks.
