Quick update.

Filled up yesterday after the first full tank (145 mi) on the 125 Jets and stock needles. I was careful to fill it to the same level or maybe slightly higher.

53.2 mpg !!!

And I didn't try to ride it gently. In fact, since I was wringing out the carb tuning I actually rode it pretty hard the last tank, lots more wot and 9k shifts as opposed to my normal slow and easy riding style.

So I think I solved it, quite by accident.

I have an '89 GS500e, recent total carb clean and rebuild, stage 3 Dynojet, K&N lunchbox filter, stock exhaust.  Pilot screws 2.5 turns out.  Floats set to high end of spec.  (More fuel in bowls)  Mix of in-town, highway, hard acceleration and normal cruising on my last tank yielded 49 US MPG.  Bike runs absolutely perfect.  (Minus a pesky oil leak I posted about, grrrr)
