Ok, just finished the complete disassembly of my 68 Norton and the "prior owner" mysteries continue. I don't have the proper machinist tools to do perfect measurements but I appear to be about .005 shy of what would be a .020 over bore, but the Pistons are GPM and marked 74 which to my research would be .040 pistons. . .
So am I smoking dope? Is this even possible?
Here's a pic of the piston
