2008 EG Standard, all stock w SE slip ons and Nightrider IED.
Did 48 mpg twice, Once with a strong tail wind and once putting around at 45 - 50 mph.
Did 24 mpg once holding the throttle open as much as I could.
WOT is kinda like a 100 mph cruise control.
But mostly 35 - 38 mpg w very little in town riding.

 

33-36 with 2009 EG Classic on the freeway with two up. 42 mpg with two up running 55mph in 5th gear. Not much of a difference.

 

39-44 mpg depending on my throttle position. Dyno'd my SERT in which gave me these numbers.

 

pure stock, except open pipes, 05 eg standard, two up loaded on trips about 42 mpg average.

 

I averaged 42.8 mpg on a cross country trip in early September. This was with two up and loaded. It would have been been better but I was tweaking the auto tune as I went. MPG started out in the low 30's and improved to a high of 48 mpg. Running interstate at 75 was 40 mpg + - depending on wind and speed.

 

Before the Fuelmoto package including Rhinehardt slipons, i got 48 to 50 on my 09 Ultra Classic. Now i get 42 to 45, but im not complaining. I get on the throttle a lot more than i use to.

 

Thank you for all the responses. It seems to be all over the board. Got 34 yesterday for 240 miles with one up.

 

I have the Fuel Moto package. If I am on a long highway stretch, cruise control on, I'll get around 45. Mostly, I will get about 35-38 mix of in town, freeway and country roads. I tend to twist the throttle more than I should.

 

2009 RK PC-V, S/E aircleaner, Rinehart Slipons 42-47

Same setup but wht stock pipes and stock map downloaded PC-V 39-41

You'll also get a little better with 45psi in rear 40psi in the front tires, also lighter weight oils in trans and primary maybe 1-2mpg more, but its hell on the clutch, and trans in hott weather tho.

 

42 - 44 on my 09 King with Fuelmoto PCV and Jackpot slipons.
