Hi Ron, many thanks for responding. You very kindly advised me to contact Brian Tillin some years ago, which I did do, and purchased his stainless steel conversion kit. I’m extremely embarrassed to say I haven’t done much with the bike for a good few years. (My excuse is that I’ve been somewhat busy with a certain TT18 Canberra cockpit!) Anyway, it’s this kit that I’m now having trouble with. Do you have close up photos of the area where the cable connects to the rod linkage. I’ve put it together how I thought it should be but it doesn’t seem right somehow!
