Cheers Jape, I know what you mean about fiddling. But I can't help myself, stuff that doesn't do what it should just irritates me and I have to fiddle with it till I get it working, even if, as you say, I break some stuff on the way. I actually stripped all the bodywork and worked from the headlight to the taillight last weekend packing every electrical connector I could see with dialectic grease. It may turn out to be as simple as a connector that's come undone, I'll let you know once I've isolated the issue. I translated a bit more of the portugese manual and I've traced the wire for the neutral sensor so provided that is still properly connected I'll just follow the wire round the bike to see where it leads me:)
