Ironside, I understand your bike redlines downhill somewhere around 75mph and probably around 9K and that you were usually around 65 which sounds very much like 8K so the engine might have been used in waste mode.
My point is that streamlining works better if at all with a big gear reduction to cruise a little below peak torque with the throttle at 75% and basically no potential for extra acceleration unless dropping a gear.
But hey, my bike is on hold with a seized rod so what do I know ?
