Mike,
I will try to remember to check a couple at 1" down the bore like originally set. I usually just get the shop that hones it to carefully measure the final bore after the minimum amount of hone to make the new rings seat properly. And the new rings are filed to fit.

There is no way I would leave this motor together for 650 passes without a tear down and checking. Mainly to look at the bearings. Once a combination of parts is working well (machining etc.) I think the bearings are the weak link for preventative maintenance. The main bearings have 300ish passes.
