These days with allot of the machines being CNC they can get the tolerances much closer than the old days, but.................
BTW: FMX I have done many rebuilds that way too. Cut the ridge with a ridge reamer, use a hone and a mic to clean up the bore, then a brush hone to get the cross hatch pattern. As long as you could do all that and stay within acceptable tolerances it worked fine. If it took too much material you had to send it off to be bored and buy oversized pistons.
Yeah I know what you mean. Like my instructor said, if the engine has some pretty bad scuff marks then it's best to send it off to get it done by a shop. Now sorry about that I didn't know this was a NEW engine. What I did when I had to hone the engines is just do basically what ProZ said and make sure that I got a 50-60 degree cross pattern and make sure the hone doesn't pop out of the cylinder so it don't bust the stone all over the place.
