I'm trying to find a flex hone so I can prep the cylinders of my 600 twin. I've done some searching online and I can find them for brakes but nothing for the application I want. If memory serves me right I think I'm looking for one in the 70 mm size and 240 grit. I talked to my local dealer and he doesn't sell them. I called a couple of autoparts stores and they were no help either.

try sears. I know they sell them, not sure if they're the exact ones you want though.

Now that's what I'm talking about.
If my piston bore is 2.94", do you go with a hone 10% larger or smaller that the bore?

always go larger than the bore.
Have you tried Production tool?

I had a local shop hit my cylinders and my 94 VMAX 600. They just lightly cleaned them up and put cross hatch back in. I have had no problems. I would not due it myself. Those cylinders cost too much to replace and there is not alot of them floating around because they are made by yamaha and still running great.
They are out of a 98 with not a ton of miles. I can still see the hatch on it. I just want to do the build right. I thought all stock jugs were nicasil'd.

Be sure to run some good oil/lube when you are honing. Just put some all over the jug and give is a good hone.
So what I'm hearing is .... some people hone, some people don't hone.
If I can find a hone I may try it but I'm not going to put off putting it together if I can't find a hone. I went back and found the post that said 240. It said something like 240 is cheaper but a 320 or higher is better to getrid of the gloss.

a 240 grit hone will rough up the bore quickly and possibly remove to much material, A 320 hone is a finer grit and will not take off as much material as fast as the 240 hone.
IMO you will need to hone a little bit so that the rings get to know the cylinder - so to speak. T
