07 RK Custom S.E. air cleaner and Python slipons. Around town and to and from work 36 to 40 M.P.G. Out on the Hiway 44 to 46 M.P.G. at 80 M.P.H. Not to many Leo,s out in the middle of Nevada.
My '06 EGC is basicly a stock 88 incher with S/E air cleaner, S/E slipons, and H-D factory download. My average MPG is about 43. In cold weather mileage drops to around 37. The best I've done is 48 mpg in the summer on a steady highway cruise at around 65 mph.
Mine is stock. Last two tanks 44.5 \\; &\\; \\; 46.9 Most highway miles. Knocking about town I get about 39-41. I have seen 51 mpg with a strong tail wind.[8D]
02 FLHTCUI SE 103 kit SE slip-ons 201 miles on a tank and it took 4.9 gallons. I didn't think I was going to make it to the gas station! The gage was well past E!
I got 42.7 last tank and 42.1 on the one before that. It's pretty rare I get below 39 after the last round of tweeking. Oh, and I weigh around 230 with a heavy throttle hand.
40.3 mpg, for 17k miles. \\; I record every fill. \\; The 1st 12k was stock, the last 5K with the PC111, SE AC and Supertrapps, which did not change the mileage at all on my 07 ultra.
