Ok two up about 340 lb plus about 50 lb of crap we picked up shopping at Harbor freight and the hobby shop.
Filled tank to bottom of fill neck (reference point).
Rode south on I 25 to Ft. Collins, ran around town for about an hour stop and go.
East to Greeley HD for the Hog fest picnic free beer lunch and etc.
Then back north and then home on Happy jack.
Speeds were mostly 75 mph with short test bursts up hill up to 90mph, and 40 -50around
town.
Low mileage light came on at 175 and we gassed up at 190. 4.3 gallons
about 44 mpg.
Less than last week, but we were loaded heavier and we were running faster on the free way.
I would guess my low fuel calibration is probably pretty close to the MOCO'x .9 to 1 gallon.

 

Sounds like a sweet trip! That's pretty good gas mileage considering the load...what mods have you done to that Electraglide?

Peace,
