Low&slow
Alan Smith is running at 6500rpm at 70mph. I thing that with his Aero ninja 250 configuration, both of you could drop the rpm down to 4500rpm at 70mph without getting into any drivability problems. You can always shift down a gear In the face of head winds and hills and if the lower gear is still below 6500rpm then you have a gear for every condition you face. With a tail wind you mite have to stop and drain fuel from the tank just to prove you had the motor on,
