gs850 flex hone size for re-ring..

[mvalenti]

So I'm reading that my bore size (per manual) is 69-69.015mm all i can find is a 2 3/4" (69.85mm) flex ball hone. Can I use this size?

(update) I have a 320grit 3 stone hone at work... is this a complete no no when re-ringing?

Yes, it'll be fine.

If you check the flex-hone site, this is listed as the correct size. Watch the videos to make sure you know how to use it. It definitely doesn't take very long at all.

On a used bore you're returning to service, I'd definitely prefer the flex-hone over a 3-stone hone -- the flex-hone will do a much better job following the tiny imperfections.

Much appreciated. Thank you.
