Aye spacer number 6 is the offending item on mine, but thankfully nowhere near as bad.
Sirch had no 5 / 20 well the dog bone (tie bar) split, so the whole assembly went really

.
Only decided to check mine as a spur o' the moment thing really, seeing as I already had rear wheel out for new tyre and finally fit the new cush drive rubbers. Obviously, this post and others recently also planted the thought to check.
My bike mechanic bro being the only previous owner, I wasn't sure whether they'd already been done at some time in the last 10 years or not. As it turns out he had done them, as the bolts holding everything together had been copper slipped and not by me. Bugger had also polished the tie bar! Why?! Anyway, spent a bit of time polishing that back up too. Still a few pits on it, will get them out if I have time.
Glad I checked though, plenty of grease in all bearings still but bad scoring on spacer 6.
Thankfully got lots of spare bits from scrapper I bought which will, eventually be my project. The suspension linkage will change to take VFR SS swingarm, so that whole arm sub assembly (7) will be redundant.
Took it to a local garage with small bead blaster today to get it cleaned up ready for spraying and asked them to fit a grease nipple while they were at it. Hopefully should get it back tomorrow. What I should have done with hindsight was take the spare tie bar for grease nipple fitting too. No more buggering about.
Chain got a good clean in paraffin last night, rear brake bled, rear caliper going to get a good clean up tomorrow.
Need to get the thing out of the garage so it can get a right good power wash - after a wet week in IOM it looks like it's done a Scottish 6 day trial! All front of engine is grey with mud
I'll have to get some more piccies to post as I go along.
