Thanks for your offers of help, it turned out it was a dodgy wire from the ignition switch that I have now repaired, I tend to get a bit dishartened over my bike, I seem to do more maintainance on it than riding, but its a fast fragile machine that seems to need a lot of care, I suppose its like owning a Ducati single. On the upside its been noticed a lot and several people have asked me to bring it to various events this summer
