Hi Redyaris, Thanks for the suggestions. I started working on my tail section and will finish it soon.

It sounds like you are starting to reach some of the inherent limits of a motorcycle with a larger engine. What you have achieved with a 500cc gasoline-powered motorcycle is amazing but to be competitive with the top motorcycling hypermilers you will probably have to go to a smaller engine machine. I love my Vision but its doubtful I'll ever break into the 80mpg territory as you have done due to its shaft drive, relative low gearing and larger motor . I agree with Craig Vetter that a 15-17 hp motor would be optimal for an 80 mph / 100 mpg capability in an efficient aero-enhanced package. The new Honda 250cc fuel-injected single would be a great starting point. I'll probably start shopping for a 250cc this winter for my enxt hypermiling project.
all the best L&S
