Looking at the guide screw pic again can I point out that the kickstart shaft splines are not great. Whilst it’s down if you can find a better replacement I’d say do it. Fit new circlip if replacing it, the amount that have the circlip ping off and it all fall to pieces afterwards when you don’t fit new is worrying. I’ve thrown much better shafts away tbh.

The selector forks are the same as the CL350 I believe, common in the USA from what I understand, maybe try and source some better ones on eBay? I do have the centre and left forks nos but they won’t be cheap if you wanted to buy them.

those shift drums will walk if that guide pin and roller are worn at all,once they jump out of gear a few times heavily the dogs round out,check the slots look good aswell,see if you can find a 550 bottom end?

Only the centre selector and drum are same as cb/cl 350
