I usually average 38mpg, but the last 2 tanks were 42 and 47.  The last 2 tanks were riding with a group so I wasn't riding as aggressive.  This on a stage 3 117 with the stock header, Street Cannons, and HD tune.

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.
Not the case with mine. Both the 12 and 17 are about 4 mph off at 80

When I checked my speed against a separate GPS it was within 2 MPH. If I recall the bike was a little high.  I averaged about 38 to 39 going to work (city and highway).  If I ride by myself and just take it easy I get around 43.  When I ride two on trips we average again around 38 to 39.  I usually fill up around 150 to be safe and usually need about 4 gallons.  My 2010 Convertible got worse mileage but I always run her hard while my 2010 Ultra averaged about 3 MPG more than the 110 CVO limited.

I no longer find it necessary to run 80 mph all the time like most of the posters. Traffic increasing over the years along with age has made slower better for me.
We still run speed limit, whatever it is, but rarely any more. $300 tickets and getting there 7 minutes quicker just do not add up.
I do get 44 mpg on my 15 with 1.75 Fulsac baffles and a FP3, got 42 on the 09 SERG with same baffles and a TTS tune by a tuner most on this site think is good here in Florida. On the 15 I buy gas around 200 and it is within a tenth or so of 4.5 gallon every time.

When run my 19 SESG down to empty and the "miles to R" says 11 miles and I fuel up it only takes 5 gallons. Is there a way to calibrate the system?

It would be nice if they included a setting in the BCM to calibrate the fuel gauge, but if there is one on the late model bikes I've never heard of it.  You could do a mechanical calibration by bending the rod for the fuel gauge sending unit, but it tends to be a trial and error method that requires a lot of patience.  An error in the opposite direction, gauge reading higher than it should, is easier to fix with a little homemade electrical solution.

If you want to make the gauge read higher than it currently does, you would need to bend the float rod so the float is slightly lower.  It's a good idea to leave a little cushion instead of trying to make the gauge exact.  For instance, when the gauge says empty and the miles to empty display says zero, you want to have a little reserve of fuel still on board.  When I did my old 5 gallon tank (actual capacity 5.4 gallons to the bottom of the filler neck), I set it up so I still have a .4 gallon reserve when the gauge shows empty.  I don't have that much confidence in Harley's gauges, and since I had to push this overweight sucker to the gas station when it ran out of gas with the gauge showing 3/16 of a gallon remaining and the low fuel light still off (back when it was new), I wanted to make sure that wouldn't happen again.

Well over 200 miles per tank?  Seriously?  You can guys can wait between pee stops that long  :huepfenlol2: ?!

I'd not be surprised that, if pushed, my longest range bike is my smallest tanked bike.  The old Evo FXR gets so much better miles than does the Road King or the Road Glide that the older bike would probably win that fight.  I can't regularly out-pee any of them though; at least not if I'm doing my regular bottle of water at a gas stop.
