I own a FZS600 which I bought new in 2003 and now has 72000miles on the clock. 3 weeks ago my 5th sprocket nut failed, this time taking all but 2 threads on the shaft with it and the last 2 nuts were the modified nut, even though Yamaha were supposed to have fixed it in 2005. Dubious of the ‘repair’ at the time I tapped the holes in the 2003 sprocket cover to take the plate and damper from the 1998/1999 sprocket cover to prevent the sprocket falling on to the shaft and leaving me stranded again
Seriously pissed off I contacted Yamaha and under no circumstances would they do anything about it, not even supply me with a new shaft, head and base gaskets free of charge, for me to to replace it myself. They even suggested I spot weld the nut on.
I spoke to my bike guru friend and he recommended I cut a slot in the shaft and put a circlip on it or drill and tap a hole at the end of the shaft and put a washer and bolt on it to prevent the nut falling off. I did both as a sort of belt and braces job.
I uploaded what I did with some pictures and since I did not know where to put it I put it under
