Drizzle persisted most of the way up, but I did the right thing heading west M40/M6 and the sun broke through as I reached the NW. The bike is superb! Everything is better!! Its got loads of power but its not lost the bottom end which I was a little concerned about. Did the slow moving traffic round Birmingham with no complaints. I didn't push the engine revs too high during the most part but couldn't resist opening it up when I reached the home stretch; again superb everything I was hoping it would be and more. Also... Its very very loud :-) I'm not sure I'll be making much use of my intercom in future hahaha.
Thanks again for all your help and advise. Cheers Julian.
