Would You be Concerned?

Well pulled the bike apart tonight getting ready to have it ported. It turns out the pistons say .50 on them so that makes it.....?over .... There is also a scratch in one of the jugs real low.... Looks like it was recently rebuilt new hot rods crank and pistons look new but would you worry about the small scratch its really low so i don't think it should be an issue .... Also You guys think it is worth porting them for a 4 mil with the bore size they have or would you get some stock bore? The scratch is on the right side of they cylinder wall its kinda hard to see.

Thanks

I am not sure what scratch you are talking about but I do not see anything concerning - at least in the pic other than they are rather glazed and need a good hone before putting them back in service.

First off i would mic them all through the cyl to see if there still round and in spec and go from there. Go ahead and port, still a few more bore's and years left after 50.
