Message	I'm currently in the market to get my engine rebored (from 87.0mm to 87.5mm). I found a machinist not far from me, who uses a honing machine from Sunnen, this one I believe : http://sunnen.com/ProductDetails.aspx?ProductID=50&NavID=655 The guy told me this was the best machine to use for that job because it "gently" rebores the cylinders, is auto-centering, is very precise (you stop the honing process as soon as you get the target bore)... Opinion are welcomed since I don't have any experience on this subject. Thanks.
