I have noticed once over 3000 rpm the fuel milage goes away fast.  I usually have cruise at 80 mph, 2900 rpm or so on the interstate.

I don't mean to be a "downer" on this post but you know Harley's odometer/speedometers are about 6% +. Which means for every 100miles you ride your odometer is reading 106. i.e. 200=212.  So a true 80mpg is about 3200 rpm's. Just saying.

This seems to have changed around model year 2015.  I have a '15 FLHTK and a '16 Roadster, and both of the speedos are within 1 mph at 75.  No, they haven't been updated either.

For the limited's you can see the difference on the nav map. Bring up mph on the screen and compare.

36 mph is what I average so realistically about 180 miles before it's time to get gas.

I'm not sure what you're saying here.

If you're saying that you can compare the normal speedometer gauge readout to the digital readout on the navigation display, that comparison isn't going to give you a useful result.  Both of those readouts use the vss to calculate the speed,  Harley doesn't display the GPS-calculated speed.  You have to use a different instrument to determine the GPS calculated speed, such as a GPS (Garmin, Tom Tom) or a GPS app on a smart phone.

If the two displays don't match on your bike, it is likely that one (probably the speedometer) is malfunctioning.  I have seen a few in the past with poor needle placement, or it could be failure of the speedo.

The tuning devices PV /TTS allow you to adjust the tire sizing to correct speed.   Also with PV you need to also look at changing the gas mileage setting as well or check it matches.   I check at 70 mph.  Farming to speedo. 

For fuel mileage you want to know is at what kPa your running at at highway speed to understand what the target afr is.  It may help explain why your fuel mileage is what it is.    Be cognizant of what gear/rpm your at and also if you are in a closed loop environment or not at that point.

For the Thundermax they when I played with it were typically rich and you "may" be able to lean up the afr to help get better mileage.  You may also want to validate speed on computer to speed on gps them being off can quickly calculate to deflated gas mileage reading.

I have the tts and have adjusted the setting for the speedometer. One question though, can you adjust it to far? If I recall it's only recommended to go so far. Will it cause an issue?

Sure you can go to far as it could skew your numbers in either direction hence validating speed either on a dyno or GPS.   Being off also has effect on mileage accuracy of fuel/mileage.  (MPG)

So I'm wondering after reading here. For me when I do 80 mph I am right at 3000 rpm......3000 to 3100. That's on a 2015. Is it different for the 2016's or 2017's? Yes I can go into my Thundermax and play with the AFR's for better mileage. Have to watch a lot of you tube videos as to not screw it up.

It also depends on what blend of gas you're using.

As we (Andy, Ernie, Don, me and others from Calif) travel east we've all noticed that we get better mileage once we get out of California and it seems like the further east we go (or is that the more gas that we run through our  tanks and motors) that our mileage increases.  On my 2013 CVO Ultra Classic I'll get 175-180 mph on the freeway (cruise control at 80 mph).  I've never got 200 miles on this bike.....not even when I was back east.
No wonder you don't get good fuel mileage. :huepfenlol2: Yes I read the rest just couldn't resist. ;D

Seems the speedometer is a little more accurate on my 17 than my 15 was or my 13 is.

My older bikes 80 on the speedometer was 77 mph on the garmin GPS.  The 17, its 78.5 to 79 mph.

I have a 2013 CVO Ultra and at 75mph I can squeeze 220 miles but that's it. At 221 I am on the shoe leather express

From new I have been tracking fuel consumption on my 2016 FLHXE. Over one year the average mpg is 42.6 mpg. That's with 6510 miles ridden.     :jalapeno:
That's all types of journeys, short, long, highway, cruising, touring, with / without baggage, basically just riding my bike throughout the year. Up mountains, along flats, around twisties and pottering along taking in the tunes.
