The reason why the threads wear out on the output shaft and the nut, is in my opinion due to sprocket chatter.
The reason why you get sprocket chatter is because the sprocket and output shaft aren't a tight fit.
If you can hand push the sprocket onto the output shaft, you'll likely get some sprocket chatter.
In essence if you have to tap it on with hammer you should be o.k., but if you can push it on by hand then you could end up with problems.
I put 110,000 miles on my last Fazer, and changed the drive sprocket several times, fortunately I had to tap it on with a hammer, and thus never had problems.
A guy I knew who also had a Fazer, had the sprocket nut issue, and he found his sprocket was a push fit onto the output shaft.... it didn't need tapping on.
