I will use a flex hone on my GXV120 to break the glaze.
-Seems the cylinder is lined but with what, cast iron, or Nikasil?
-Which grit does Honda recommend (120, 240, 320...)?

Thanks, Kevin

It will depend upon what type of rings you are fitting and what the bore is.
Coated rings need very fine hone
Steel rings get a fine hone
Iron rings get a coarse hone

Not sure what they are, did not know there were different kinds. I just know I purchased a standard ring set Honda PN 13010-ZE6-013. Can you tell me which type they are?

Could you back up and tell us why you are fitting rings? Can you get an accurate read of bore ID?

It is burning oil.
I have not measured yet but will try new standard rings first. If it needs boring I might consider a new mower.

Pretty sure I have it narrowed down that I need a Silicon Carbide hone but not sure on the grit, considering 240, any input?

I've used a brake cylinder hone, I bought at a N.A.P.A. to hone the cylinder of a Sears Gamefisher (Tanaka) 3.0 hp outboard. After installing new rings and a new piston, the compression is about 105 psi.

Is is possible the oil loss is through the valve guides?

I have a 240 grit silicone carbide Flex Hone on the way, thanks for the replies.

I havent had much luck getting an even cross hatch pattern with the spring type 3 arm hones. Go past the stone pivot point in either direction it wants to pull or push itself in or out of the bore. I have also had issues with chatter but that is probably because it needed new stones. With a ball hone you can go in and out fast enough to get the pattern desired much easier. Since I am reinstalling standard rings I will only make a few passes with the hone in and out just enough to remove the glaze and take off as little material as possible.
