I just got back from the machine shop and the guy tested it with a meter that goes right into the bore and we found out that at the top of the piston (near the deck) the measurement is 73mm and in the middle and towards the bottom the measurement is 75mm. He told me that the Honda blocks tend to go "egg shaped", so I'm going to do a fresh bore to 75.5mm and everything should be just fine to accept my new pistons. I also got a good price on Honda OEM rebuild kit from him so this should really work out good. The price he gave me was $175 CAD for the pistons, rings, and pins (I believe the pins come with it). Thanks for helping me out.
