Bonjour Richard,
the OP has just had some good advice because I spoke with Andreas last year and he was very helpful. Sometimes one gets lucky and meets someone who is just so intelligent and curious that one can go to them with any problem that one can't solve oneself. I had that with a chap who was also the guru in the south of France for the Honda SS 800 but he retired early. I do what I can for myself and keep my fingers crossed.The nearest agent is in Toulouse. The only thing I miss about England is BHM. Thanks for including me.
