On the way out, on the super slap, I had to stop every 150 miles. On the return trip I was able to get to 200 miles before stopping.

I read in American Iron magazine, years ago, that optimal mpg on big twins is 52-53 mpg. Which I found to be true on a trip through Wyoming. It sucked running that speed, got passed by an old lady in an Yugo, but it saved me from pushing.
I pulled into the only gas station for miles and put 5.013 gallons in the 5 gallon tank on my Fatboy.
Yep.. Also, the higher the altitude the better the gas mileage. While up in the mountains of Colorado and The Dakotas I was getting 50+ mpg.

I agree with Pitbull's statement.

I have a 17" stock and a 21" Klockwerks Billboard Flare windshields.
Up until yesterday I'd swear the Klockwerks shield cost me ~3 mpg and I'm still not totally convinced that it doesn't but I now question that more.

After a 350 mile Black Hills ride from Rapid City to Devil's Tower to Deadwood to Needles Highway and back to Rapid City with the Klockwerks shield and only 12 miles on I90 at >65 mph I ended up getting 47 mpg.

Prior to that run my best was ~42 mpg and that was with the 17" stock shield.
BTW- around town I use the 17" stock and get typically ~38 mpg.

I get about 30-35 depending on how I ride, if I wanted "good" gas millage I would have bought a Prius

Get about 42 -43 riding easy as I can and between 60-70. I usually ride a little harder than that and get 35-38. Stock 103 with a powervision , stage I and a pipe.

, Same here. Gas is the cheapest part of operating most any motor vehicle, and I`m not concerned with gas mileage while riding mine. Besides, who cares when most of the time you spend less than $15 to fill up your tank anyway?

For those of us who do care...(because why the f**k would one bother to respond to a question with an "it's not important to me" comment; as if having an asshat of an opinion somehow trumps any relevant information?)

I run with or without a king size windshield depending on my mood.

I ran for years without a shield before I started using one. I always averaged around 45 mpg combined. I don't hot rod but I wouldn't say I take it slow either. I just sort of go with the flow for the most part.

Once I started running a shield I noticed about a 2-3 mile drop in fuel economy averaging only about 41. After many years of running these two setups under the same conditions I feel its safe to say that the shield for sure takes away from my fuel economy more than any bags or sissy bars or anything else on the bike which I ran with for years before I ever went to using a shield. I can dump the shield and instantly see the fuel economy go back up.

Do tires seem to make a difference??

Jeez skeez! Probably can get a few more mph if ya pop it in neutral on downhill grades and maybe catch a draft from following extra close to vehicles on the highway. Honestly the single most unimportant factor was mileage when I bought my bike. Just another asshat of an opinion but wtf im off today and im that bored.

Ya know, I really tend to agree with you on who gives a ****, but it just pisses me off when one or two guys say they get 225 miles on a tank & I get 140-150. Makes me think I got a lemon.

No it's not a lemon. It's just the tune and how hard you ride it. A guy I ride with always gets about 50 miles less out of a tank than I do, but he had his bike tuned rich. So rich in fact sometimes I hate riding behind him because of his "ripe" exhaust..
