Nuts, chains and sprockets.

[BluprintZ]

I suppose i'll contact Yamaha and see what sort of a response i get from them.
The thing that worries me at the mo', is that i've already tried to fix the problem, by buying and fitting the new 12mm nut, knowing that the O/S is damaged.
Yamaha could well say that i should have left it alone, once i removed the old nut and saw the damaged shaft, then contacted them about the freebie repair!
Anyway, i'll give them a shout and see what happens.

Thanks guys.
