Just been reading this with interest, as I get the feeling it's something that appears to be an inherent fault that's waiting to happen. Would that be a fair assessment?
What I'm wondering now is can the bike be retrofitted with new parts that correct the fault, or will replacement of the damaged parts mean it's just going to happen again at some point in the future?

Thank you for that. Is it something I can visibly inspect without pulling too much of the bike apart?

Bill's original post was brilliant but far too much engineering in there for me but it certainly raised some issues - I liked the idea of the clutch plate with the spacer (there was a link on here somewhere) so more of the shaft was supported but the offset dowels on Bill's was amazing (at least to me) engineering work

Yeah, that looked pretty good. I guess the problem is it's not like you can just idly strip it down to have a look - you more or less have to take the whole bike apart if you want to see what's what. And not all of us are Engineering geniuses capable of measure the alignment, as per that post. I guess we have to assume that in the first instance the problem may manifest itself due to lack of lubrication when the bike was built.
For now I guess I need to get the rear wheel up in the air and stick it in gear, and rotate the wheel, and see what play I'm getting. Next question is whether there's a measurable amount of play - what's acceptable and what isn't?

I'm not sure you could make a sound judgement on that basis, there are far too many parts that could have wear between the rear wheel and clutch.
Unless you are doing the clutch or are handy with spanners, i would be inclined to leave it alone unless you have a problem.
My unprofessional opinion is that it is an inherent problem with this type of transmission layout exacerbated by less than ideal lubrication in the factory.
Input shaft replacement is (partly) covered here

A good 2nd hand gearbox makes a lot more sense.
