I range everywhere from 38-45 depending on head wind, speed, and everything in-between. I don't worry about it unless the standard MPG is 35 (consistently). At 31 you should be running rich enough to see a lot of soot not only only your plugs but the inside of you pipes. You will need to take a good look at your fuel map's. If your's has a SERT either get handy with map manipulation or a Dyno might be in order.

I got low/mid 40's stock. Made mod's (see below) and get 28 into head wind and 32 with tail wind and 34 with the wife on back

It is tuned rich.

The best I can get is 36 mpg. I'm thinking to get a six speed.

There are three places around Topeka to get non ethanol gas.

I have a 10 week old FLHX, she's still just a baby, and ride mostly 2 up and only get around 32-34 mpg. Rhinehart 4" slip ons. Rode across Alligator Alley and back with similar cross winds from Sandy here in S Florida on Saturday. Rode 320 miles. Tank and a half. 34 mpg was the best I could get. Riding mostly 75 - 80 mph on the same fuel.
Your bike is a sail in cross winds like that.

The only hd's i see getting 50 mpg are light sportsters & dynas not heavy ultras.

Don't worry about internet bullshit as when you ride with these guys that get 50 mpg riding at 80 mph all day and monitor the bike & fuel intake for them they start coming up with excuses as to why suddenly there fuel usage has gone up.

Higher speeds will drop the mpg quite a bit. Check your tire pressures to make sure they are up to spec, lots of other good suggestions here. I am averaging just a bit over 45 mpg on the RK and don't usually worry about fill-ups until I get to around 200 trip odometer miles.
