Just a little musician humor...
I'm Paul. I have a 2005 Chrysler PT Cruiser that gets terrible gas milage and I have a 1990 Harley Sportster that gets bad gas milage for a bike (it gets about 35 mpg). Anyway I am looking to move to a better mpg vehicle when I can.
Just curious, what cc is your Harley? My dad's gf has an 883 that she claims gets around 50, but it's pretty much stock.
My dad has a royal enfield, 500cc single cylinder that gets about 70mpg!
For any of you who like to ride motorcycles for good mileage, the Enfield is a pretty good choice. It's extremely fun to ride. That said, you must be willing to maintain it constantly, as it retains the same technology enfield used in the 50s. ie, points, valve adjustments all that crap.
