I'm intersted in this too actually. I've just got a bike from Lammas Group and am looking at the same upgrade package.
I'm put off if I have all that messing with the carbie just to get it to fit. I'll probably end up buying the parts sepertely intead and get the Dell'orto 14/14.
Also, I notice that Ozminimoto doesn't seem to sell teh full Fatboy exhaust. I'll have to give them a call and suss out what the deal is and get some advice...
If you get any more information though 'dim' then post it up
