So this question is referring to the cylinder on my gs550. I measured them a couple weeks ago with a bore gage, and everything was within specs with just a little taper top to bottom so I ordered a new set of stock size piston rings with the intention of just honing and installing new rings.. So the rings got here today so I finally hone the cylinders after work. Everything looks good until I get to the last cylinder and I see some scoring after the first pass. So I went a little more with the hone until the taper was gone and the cylinder is about +.002" oversize from nominal which is within the service specs but I don't want to go farther because I think it would take going over the limit to totally remove them. The rest of the cylinders look beautiful, but this one has the two scores shown in the photo which will just barely catch a fingernail.
So now for my questions..
should I
1) just put the beast together and run it as is
2) keep honing til the scratch is gone even if it goes oversize a little
3) go +.5mm (which would stink since I already got the rings)
4)?? I dunno what else I guess I could have a new sleeve put in but that's a pain as well.
I appreciate your opinions.
note: the marking at the top that looks like a scratch isn't it is just where I ran the bore gage down checking the diameter..
