So...knowing the following:
865 cc = 54hp@6750, 51ft.lb@4800
790 cc = 61hp@7400, 44ft.lb@3500

I dont see it impossible that an America or Speedy with the 790 motor could get up to about the 70hp/50ft.lb range. Especially if its getting the fuel and air needed.
After looking at some other info:
Specialty Spares claims 65 Dynod HP with their pipes (Iassume on a 790), UNI and jets.
Thunderbike claims 68 Dynod HP (on a 790) with pipes.
Sorry...no torq info from either. You get the point though.

Whats really bugging me is that those of us with newer 865 cc bikes will only get minimal increases.

Thoughts anyone?
