Default Re: machine new cylinder?

I had a PK80 that died die to my own mistakes, and it went through 2-3 owners before me on the OCC, and even though the motor ate some metal (my fault), the cylinder finish and hone looked pretty damn impressive compared to what I'm used to seeing in small motors.

I didn't put a bore gauge in it to see how wobbed it was, but I couldv'e sworn my engine had a ferrous liner too, maybe it was a Grubee Starfire instead, I dunno.
