Mileage from Wichita KS to Mahoney State Park NE and then to York NE (strong head and cross winds) was 24.02mpg. The trip from York NE back to Wichita KS dropped to 21.19mpg. Not bad with head/cross winds at 30-40mph and with gusts to 50mph.
I'm working on bolting the trailing end of the duck tail to the aero cap with some ovaling to allow movement fer the hatch when lifted up. The front end is still taped back down with Gorilla tape...
