I used a semi-circular section of a plastic bucket, flattened it somewhat into an airfoil shape, and attached it to the front fork struts. This turned that huge speedbrake hole into at least a crude airfoil shape, reducing drag and buffeting significantly. I get about 51 mpg cruising at 80, ~10-15% better than other similar BMW bikes at 70.
Would you have pics of your bike ?
Not that I can't imagine how you had it done, but a pic is always nice to look at.
