I agree the O/S thread looks bad but as i mentioned in my last post, i recon the fact that the torque wrench was clicking at 90 Nm, was probably because the new nut was cutting a thread into the shaft.
I do have access to a very good engineer/welder, although whether to go arc or mig, i will have to discuss with him.
To be honest, now that i have a new chain, sprockets and the 12mm nut on, i'm inclined to let him wend the nut on, as i few on here have done...i think?
I should get a few years out of the bike if i look after the chain but to say i'm rather gutted, is an understatement, i really was happy with the bike, until this shambles unfolded.
It's probably too late to go shouting at Yamaha for a new shaft to be fitted, although i might do, just to see if they will honour the fact that they have messed up with this issus.
Thanks for all the advice guys.

Worth a try at the very least!
When you speak to Yamaha show them the service note number: [size=1em]SERVICE NOTE 2005-12A[/size]
"....Any FZS600 Fazers model (1998-2003), regardless of whether it still in warranty or has been serviced officially in the Dealer channel can be inspected at any official Dealer. Remove the existing nut and washer. Measure the drive shaft OD of the threaded part (micrometer or vernier caliper). If >= 17.5 mm - clean threads and fit a new washer & nut with threadlock. If < 17.5 mm - the drive shaft must be replaced. (This work could take between 1 day to 2 weeks depending on dealer workload)...."

Has to be best first option - a new o/p shaft fitted for free? You couldn't turn that down if they'll do it.
2nd option, I'd look at the weld and recut solution - hopefully it could solve the issue on a permanent basis, whereas welding on the sprocket nut maybe will just cause headaches later.
