JD, thanks for sharing your experience. I'm chalking up most of the difference to dirty aerodynamics -- the fairing was broken off the bike, and there is nothing except the headlight shell. Throw in soft luggage hanging out in the breeze, and my big carcass on top, and I'm sure it makes a brick look sleek. I do believe that getting the EFI mapped better will result in an improvement as well -- it's a bit soft on the roll-on at highway speed. Oh, and I forgot to mention 2 mechanical issues - the waterpump seal leaks, and under full-throttle acceleration the clutch slips slightly. I doubt that it's slipping at highway pace, but I could be wrong.
