I only get 38 MPG with my Electra-Glide.
If I set the cruise at 80, I can drop it all the way down to 35 MPG. If I keep it down to 65 MPH or less, I get a solid 50 MPG. The only performance mods are the Screaming Beagle air cleaner, the “off road” mufflers and a remapping of the ECU by the local dealer. I especially love the “Parade Mode”; it really helps keep the heat down so you don’t cook your inner thigh.
Gotta love that Delphi fuel injection!
That's my magic number.

38 miles to the gallon. :-)
