While its apart, have you thought of fitting the 674cc big-bore kit as used by some of us Desmodue racers this year?
It didn't make as much difference top-end as we had hoped but the extra 91cc would add a nice bit of extra torque for the road.
Also I just happen to have one coming up for sale as I'm going back to 583cc for next year.......
Have a word with the Baines bros and let me know if you're interested.
Cheers, Paul
