Your back plate securing screw is nicely in the middle of its adjustment range👍

My lower shock bushes pressed out without difficulty after 50 years using two sockets in a vice after heating the area using a mapp torch. Cheap to replace and you are having frame repainted anyway. Gets round all the hassle documented by some other methods

I agree with your approach using our real advantage as time rich private restorers. So what if takes hours - getting an unstressed connection at the ports that you don’t have to worry about will be worth it. Too much to hope that these aftermarket units would just bolt on but your patience is going to be rewarded.

This might help you a bit. I fitted the the 2.5 mm thick 90 hardness rings after reading this and they've been fine

CB500/550 / Re: Rear wheel rotation stiffens up when tightening axle problem.« on: May 09, 2024, 11:26:04 PM »In concept, the inner race of the bearings form one complete tube along with the other bits mounted onto the axle, tightening should clamp all those elements tight together in one continuous load path.Thanks for that helpful clarification. I remember now what the issue was on a front wheel. After shouldering the first bearing continued driving inward of the the outer race of the non shouldering second bearing using a socket jams the the inner race against the separating tube and introduces side load by pushing the outer race further inward. It’s a matter of feel to decide when to stop since there is no shouldering of the outer race. So to get a free spinning bearing I had to pull it out slightly again. When tightening the spindle with its spacers fixed length of the inner race assembly prevents excessive inward movement of the outer race. 9

Good fettling Ted. Sounds like you’re getting close just as the weather is picking up👍
I’ve previously been confused by the interaction of the spindle clamping and bearing fitment on other bikes. . Inner races spin easily after bearing fitment but then are pressed against the spacer tube by tightening the spindle. I’ve changed bearings thinking they were tight only to find they were fine once removed. Am I missing something? 10

Thanks Flat four I’m going to have to keep an eye on that oil level! Looking into joining the BMW club. As always now there are some superb video tutorials on you tube an absolute god send and I’ve already stripped the bike and figured out what tools I need - virtually 👍

I’ve seen reports of worn carb body where needle jet seats allowing leakage around the jet. Worth checking.

At the cheap end of the spectrum I got this set for £12 and it’s worked fine the few times I’ve used it.

Looks like an opportunity. On their website they only list a system for cb500. Presumably no good for a 550 k1 ?
