I think someone on here has welded and also i someone tapped drilled and tapped a thread in the end of the shaft and did somthing.
Sorry not much help but perhaps you could help me as over the years on this forum I have not come across any 98 reg with the issue unless the sprocket has already been changed before. Do you know if the sprocket has been replaced before - how many miles has it done.

The sprocket has nothing to do with it, it's presumably that poxy ill fitting 9mm nut.

This bares out as not all bikes after the original 98 have the issue and after a certain year they don't either,

Which bit.
I have to say its all my own assumptions and theory based on what I have seen and read over the years on this forum and based on my own bike, some people have it some don't and as of yet no 98 has it - remember as above no 98 factory original untouched. 
This is why I am interested in marcus2066 as his avatar say 98-99 bike and he has the issue 

EDIT
Juts read the posters other posts and he has a 99 with 39k miles and reported the sprockets looking new.
So its not a 98 and the sprocket looks like has already been replaced.
So yet again I cannot find any evidence to disprove my theory.
