Progress report:
First of all, what a doddle these bikes are to work one. Old school and I like it that way.
Pulled the clutch actuation bits and found the needle bearing on the lever completely seized and also some light witness marks on the plastic piston suggesting it may have expanded when hot and jammed in the housing. If freed up the needle roller and re-greased it with LM grease. It’ll do for now until a replacement arrives. I mic’ed up the plastic piston and it was 28.96mm dia, so I skimmed it in the lathe and brought it down to 28.86mm. Lubed it lightly with moly grease and refitted it. Everything feels nice and smooth so I’ll give it a try once it stops raining.
