I bored out my D16A6 cylinders today to accept .020 inch factory over size pistons but screwed up on the last hole #2 using those Kwik-way boring bars.
For some odd reason the boring bar didn't want to align and only cut out 3/4 of the diameter of the cylinder.. I tried aligning it over 5 times and I know I did it right, I don't know if the cylinder is shaped like an egg or something.. I ended up boring it out to 2.9770in from my planned 2.9700 to be able to cut all the way around..

Now my problem is should I buy .040in pistons or resleeve the cylinder? I already purchased the over sized pistons and rings from Honda. I'm also worried about if my boring was off then the piston will be slighly off center from the rest, is this very critical?

Any help will be greatly appreciated.. Thank you

I would check w/ a reputable machine shop. If you go .040 over you may not leave yourself enough if you need to bore it in the future. Walls will be thin. Just my thinking.
