Use the 5:1 airfoil and a 25% kamm cut as the beltline (X-Z plane). Curve to the top and bottom using ellipsoids. Use the 3D graph option on a spreadsheet to match your bike dimensions. Max width between the the handle bars and the shoulders. The rounded shapes will reduce wind loading and could generate a bit of down force if the minor axis of the lower part is greater than the top part. If max width is 24 inches then overall length is 90 inches.
