I got around to checking my MPG on my raod trip from NoCal to SoCal. It was 1070 miles. I ran from 70 to 90 but the most of the time 75 & 80.
I use my cruise most of the time. I got 44.125 MPG. I'm all stock 2011 FLTRX 103. It was 90+ about half the trip. I was using HD 20/50 dino. It ran great. When I got home I did the 5K service & went with Redline in the engine & primary. I have been using Redline Shock Proof in trans since 1K. As long as don't have any problems I'm be leaving it stock. Of course that's what I said about my 07 FLHT STD but it made all kinds of rattles on a pull around 3000 rpm. It took me until I had 16K until I did muff,A/C & re-map.
So is that a good number?

 

I'd say thats pretty good mileage. I got a tad over 40 mpg from Kingman Arizona to Los Angeles on my 2004 Ultra. It's an 88 FI with Scream Eagle exhaust and a chip) This was about two months ago when the temperature was a little cooler and like you left it on cruise. (averaged about 75 with some strong side winds)

You have a beautiful bike. Not trying to spoil your emphasis here, but unless there is something making you wonder if you bike is seriously using an inordinate amount of fuel-take your mind to the freedom, the road, the country, your significant other, the camaraderie-and to hell with the gas stuff! Ride safe and enjoy that ride!!!!!

 

That MPG is right inline with my stage 1 09 EG Classic, and my Pal's stage 1 '11 Ultra Limited 103".

We tend to run about 65- 70ish much of the time ( 2 lane roads when we can). we get identical mileage measured over thousands of miles.

Your sharknose probably pushes through better, so you can go faster for less energy.

My bike has been 38/39. city and highway. Id like to see more. Its all stock

 

I got 44 MPG when mine was otherwise stock with SE AC and V&H exhaust. When I put in the cams and the 103 kit it dropped to 40 MPG. However, above a steady 75-80 MPH it dropped into the mid 30's (pre 103). I think this is because I had to keep the throttle opened enough that it put the fuel injection map into the acceleration enrichment area. Haven't had a distance opportunity since the 103 kit to see what happens in the 75-80 MPH range now.
