Hi RichLees, Thanks for your reply!!
I heard about Ernie, in fact I am in contact with him (just for advise). The only problem is that my bike is in Germany, so Ernie doing work on it is not really an option. From your profile I can see you are in London (is that still accurate), I'm in London too (till mid March) would it be possible for me to have a look at the job Ernie did on your bike? Then I could find a welder (with a little experience) in Germany and ask him to do a similar job. Needless to say, if you cant be bothered, then that's perfectly OK. Or maybe you have detailed piccies of your motor posted on the web?
