Rethreading Axel

The chain on my Yamaha YZF600R broke the other day. When I went to replace the chain, I noticed that the front axle sprocket had fallen off. I also saw that the nut, to keep the sprocket on, was missing. I bought a new nut, but found that the threads were stripped and wouldn't hold the nut.

My question is, would there be any problems with just rethreading the axle for the nut, besides having to find a new nut?

Here is a link to the diagram of the axle(11) and nut(28).

I assume you are certain that it's the shaft that's stripped and not the nut.

If the threads are just dinged up then you can clean/freshen them with a die. If the threads are stripped as in gone then I don't think there is much you can do as there is no metal there for re-cutting the threads. You could have a machine shop thread it for a smaller nut but I think the shaft would have to come out to put it in a lathe.
