I have one stripped stud (sprocket bolt) on the rear hub of my bike. After searching for the proper size threads, I found out that it's 12-1.25, but that die isn't easily available and I don't think it would fit.

Honda shows a seperate part number for the stud, so that tells me that it can be replaced. However, it's not like an automobile one that can be pounded out the rear. How do I get it out?

It can be done with a torch to heat the hub around the stud and if you can't double nut it, you can use vice grips.

If it doesn't pound out, it must thread into the driven flange. I didn't see anything in the service manual about it though.

Me neither. Reverse threads?

What is the torque value on the nuts? It's listed as 80 ft-lbs which seems really freakin high to me since the axle nut is only 69 ft-lbs. I thought it was my torque wrench out of adjustment, but some Yamaha forums were talking about theirs being too high in the manual and a revised manual came out with much lower values.

The stud threads in so don't pound anything......

Yes using heat will make it much easier to get out.

If you are unsure which way to turn it, well you do plan on having the replacement on hand before you start the repair, right (they are a whole $1.50 or $2.22 list) so you can just look at the replacement to know which way and how much you need to turn it to get it out.

Oh and yes it is supposed to be 80 ft\lbs.

I would be careful with visegrips. Use as many pair as you can get on it at once or better yet, get a bench vise (removed from bench if needed) on it. You'd be amazed how much more force you get with a bench vise than vise grips. It saved me more than once in similar binds.
