I'm set up similar and get about 38 highway. City mileage with hard takeoffs would bring me down to about 32.
Thank you for you comments, looks like the numbers are about right with my set up:mad31 is right around what i have gotten out of 2 different Ultra Classic.
They could be SE-204 the PO didn't know much about the mods.240 cams ?
You sure its not SE-204 cams !
Looks like your gonna have to pay dearly for that 10 HP increase . Is it worth a 10 MPG hit ?
Although the HP & Torque figures are pretty dog-gone good .
Yes, my calculations were made using gas pump. I went for a 120 miles ride and I used almost 3/4 of a tank.: what?You are definitely not running rich, IMO.
I am in the 36-38 with mixed use and can hit 40-41 if I stay below 70 mph highway cruise. I have stock cams though.
Are you calculating the gallons using the gas pump? I only ask because if you are assuming you are pumping six gallons into the tank, you may not be. It is actually a bit of a tedious task to fill the new tanks completely full.
You might be able to lean it out a little, but I don't think you will see a 7-8 mpg improvement. That dyno run shows the bike is set up to make good torque a lower RPMs. It takes fuel to make power, and you are making power right in the sweet spot of the cruise range.Thank you for the comments,
So guys, the A/F readings are good based on the dyno chart?
If am in the 38-40 mpg range I be happy.
Can I gain the extra miles with a fine tuning on the SERT or replacing the cams is the only way?![]()
You can NOT go by the fuel gauge !!!!!!!!!!!!!!Thank you for the comments,

Cool,You might be able to lean it out a little, but I don't think you will see a 7-8 mpg improvement. That dyno run shows the bike is set up to make good torque a lower RPMs. It takes fuel to make power, and you are making power right in the sweet spot of the cruise range.
Thanks Webco2, that's how I do itFill tank Full to the top, set trip odometer , go for a LONG putt, fill tank back to the top, record how much fuel you used and how many miles you rode.......do the math .
Your setup now is almost ideal . The little that you may save on fuel by changing it all back will not equal the "fun-factor" you will lose .Cool,
So am going to do my homework to see what all takes to do the cams to return her to stock internals.
Am getting too old, speed not a factor, just want to cruise across the states and not doing it 150 miles at the time.![]()
I agree:thumbsupYour setup now is almost ideal . The little that you may save on fuel by changing it all back will not equal the "fun-factor" you will lose .
That's always an optionIf you just have to have more miles between fuel stops, you may want to look at a Aux. fuel tank .
