Honda-SOHC

Hello,
 I'm in Paris, France. I am a retired and enjoy this time to upgrade my old bikes. I've retyped 2 (750-K2 and K2-500). Currently I go back one GL1000 K3. The frame is finished and I'm working on the engine.
 I do not speak good English so excuse me for the mistakes. I'll try to post a picture but again it is difficult. I use "imageshark)
 I saw AshimotoK0 trying to make "rubbers for primary driven" and I interress much because I think many people would interressées. In France there is not.
 I disassemble several "primary sprocket driven" and they are all useless. There are two sites that offer (M3 and cbfourclub.de)
 M3 is expensive $ 150 and the other must subscribe.
