I have an 08 UC, was getting 45-47 before I put the Vance & Hines slip-ons, SE A/C, and SERT on. Didn't have enough good riding weather to find out what it is now, but suspect it has gone down at least a little.

 

43-53 MPG
05 Road King Custom
TC88
SE A/C with paper filter, switching to K&N filter next week
2" Rush slip ons
Caburated
Northwest Mississippi

 

A pretty consistent 42mpg. I'm at sea level.

 

I generally get 39 mpg on 02 Ultra. I think maybe I have a heavy hand on the throttle as we usually cruise in the 80-85 mph range.

TDA69 and Windup. I too have an 08 Ultra Classic that I just ourchased. Currently have 700 miles on it. I live in texas and am only getting about 200 miles a tank. that doesnt seem very good to me at all. thats only about 36 miles to the gallon with a stock bike....do you think it could be that the ibke hasnt completely broken in yet???? I wanna go with the fuel moto set up but HATE to make my mileage worse you knw?? whaddya think?

 

Mileage depends on throttle input for me, I have gotten a high of 51 riding down from Sedona Az to phx at a nice slow 55-65 pace to as low of 26 when blasting farm country at much higher speeds, I seem to average 41-43. OnceI rode to Redding Ca from Chico Ca with a almost constant headwind and got 31 mpg and with the tailwind on the return much better at 48.

 

Ihave500 miles on the bike even completely stock at best only got 32 mpg- i tend to ride kind of fast , i ride everyday, most of my ride is on the freeway.
i wonder if it matters when in the year the bike was made???????

 

was a typo i have 5000 miles on the bike,
up for my next service i run syn 3
