The bore guage says those scores are 1 1/2 thou deep and the cylinder about 6 thou over spec. Tore down the second one, the cylinders looked better but one cylinder has 13 thou taper and the other 14 . Have one more I could tear down but expect its just as worn. Think I'll price a set of pistons and try boring it out.
I've never tried this before. The bores are deeper than the stroke of the quill, do you use the quill stroke then raise the knee for the rest of the travel or do it all with the knee travel?
How much under your desired size do you bore to leave material to hone?
The original bore is 3.250, for a 20 thou over piston do you go 3.270?

Free advice is worth exactly what you payed for it.
