Hmmm, A three leg flex type hone usually gets me into trouble here on 4 cycles as they just make out of round and taper conditions worse. The ridge hones I use have two stone and two wipers so basically there 4 points of even contact. I use flex type hones for just as glaze breakers if just rings are worn out so the new ones will seat properly.
There have been times that I need to hone to nearly the next oversize before I can get the out of round and taper removed. I had one recently that I was at .018" over before taper was gone on a .020" over sizing. I was getting a little nervous to say the least since I had already order the oversized piston set.
It sure would be nice they started making .030" overs again and not just the .020" overs. Probably not enough material nowadays for doing .030" oversizing though.
