Trying to improve gas mileage has been something that I have been working on for a while. I have an 08 Ultra Classic with Rush slip ons, SE Air Cleaner and a Fuel Commander III. It was getting about 40 MPG on the road. Got rid of the Fuel Commander and replaced it with a TTS Master Tune. With this setup, you hook your laptop to bike and go for tuning runs. After tuning runs, I got my mileage up to 43 average over about 1200 miles. That was with a corrected speedo/odometer that you can correct with the ECM flash. Then I had the dealer install an Andrews 26H drop in cam replacement. WIth a TTS retune of the bike, I am now averaging 44 MPG after about 500 miles. The bike runs better, has more torque and power, and gets better gas mileage. Now the 44 MPG would calculate to about 45.5 with the original speedo calibration.

 

i get between 36 and 42 mpg with my 07 Ultra depending on how and where i ride,,,,,,i aint real sure about the high 40's just dont seem right to me i sure do wish i could get 48mpg though ! maybe they get that down hill or something ...hehe

and WTF!!!! 7K for an 07 Ultra ???? man what a deal ......with all that money left over you could run 15 mpg for few years and still be way ahead !!!! And be the chrome king of the niehborhood !!!! LOL !!!

 

since i changed to a full synthetic my milage is about 45 mph highway and 40 on the

streets-ride safe

 

i have the same year, same riding style, and get the same mileage.

 

Yeah, well. It was one of those ebay deals. Salvage title. Mechanically in great shape with low miles. Needed cosmetics and some TLC. Checked it out real good before I bought it. Figured it would be hard to go wrong for that price. Put about $1500.00 more in it so far. Happy as a pig in slop with it. Even the MPG I can live with. Look forward to a long and happy relationship. I guess I don't ride as conserative as I thought. According to some of the other post. Like everyone else I want to keep riding and never have to make that pesky gas stop.
Ride Safe!

 

I am shure you are one of those people that believe every thing people tell you with out investigating. Do you comprehend how many lightning strikes the earth has every day? How much ozone that is produced from a single strike? I will bet you think that Al Gore is right that mankind is causing global warming. Answer me this if you can. What brought the Earth out of the seven ice ages before man kind. Hug a tree for me will you. I have to go out and fire up my evil carbon emitting Harley and ride down to the ozone producing gas station to fuel up for the run to the coal fired power plant that I work at so I can produce power for the EMF producing appliances that you use. Give me a break and stop spewing all of that liberal brain washing you have been fed and stick to harley stuff will you? Oh and by the way I get 44 mpg out of my carbon emitting 09 FLHTC

 

I did - just a matter of how it is tuned.

 

My 99 Roadking was getting upper 30s - I took it to the local Harley dealer and they found out I had not had some special tube replaced - Factory recall!! After that my MPG was up around 45 on the hiway..35+ in town.. Check for factory recalls.. By the way, mine is carburated.

 

Back in Dec. on a 3800 mile trip my ultra averaged about 113 mpg, but i trailered it about 2500 of those miles!!!!

 

And also a matter of how it's ridden. Most folks don't ride/drive nearly as economically as they think they do!
