Sounds to me like yours does need that valve adjustment or some sort of work done, because both of my GS 1000g bikes also always got between 50 and 60 MPG, much to the dismay of my riding buddies on other 750 to 1100cc bikes that rarely seemed to get much over 40 MPG!

British gallon has 160 FL. OZ, U.S., 128. Only part of the difference.

I am looking at one, but it's been sitting outside a while. Looks to be all there. Guess it's a basket and I'm not much of a mechanic, but it seems like it's a classic that needs saving. Battery is dead.

Sir,
I would like to add my two cents on this matter. I have a 1980 GS850 GL.
Now, I removed my air box, added pod filters and have a 4 into 1 exhaust that feeds into a (baffle removed) Vance and Hines. All this extra air flow required me to go 20 up (yes, 20; not 2) on my main jets. I average 45 MPG, and have seen a touch over 50, straight highway (60-65mph), solo riding. She is wearing Avon Roadriders.
This leads me to believe, someone with a slightly more restrictive exhaust and maybe only 5 up jets could possibly see over 50 MPG on a regular basis (keeping out of the throttle).
Hope this helps, ~Derrick
