scorch, good job getting 78MPG!
The mythbuster segment shows the effectiveness of streamlining but their streamlining is pretty crude and way larger than it needed to be. Too bad they didn't contact me, Alan or Craig to show them what good streamlining looks like.
For the easiest, best bang for the buck effort, read my Aerotrunk thread that I posted in the Cargo section. It covers the construction of the aerotrunk as well as details the improvements to the stock 2005 Ninjette( taller gearing, aero, windscreen, enclosed front fender. If you are not into fabricating your own stuff go with the taller gearing and a taller windscreen. Those improvements with some efficient ridning should easily get past the 80MPG barrier. YMMV
