In April of this year my 84A got 42-46 MPG on a 800 Mile trip to Tail of the Dragon. We ran anywhere from 65-75 MPH on most of the major highways.

Pretty bad when my car(VW TDI) gets better mpg than my Wing. I've gotten upper 30's and low 40's. Just rebuilt my carbs, sync, plugs, & wires. Hope it comes up to mid 40's. I'd be happy with that! I could get 50mpg on my fuel injected 2000 BMW K1200LT(sold it).
Mid 40's with my Wing will make my day!

I get 37 pulling my trailer with 2 riders, and 40-43 without the trailer, and 2 riders. About 46 with just me on it (84 1200)

I get 40+ mpg driving around town. Haven't had it on long cruises yet. Mine was re-jetted by the original owner and has not been synced since. That's my next project. Oh yeah, it has 107,000 miles on the clock and still runs strong.

my 84aspy got 33-36 pulling trailer with 2 up. I get right at 42 without trailer. I also noticed a BIG difference on milage depending on what state I was in. Texas has some rotgut gas....MPG is the 33 end...The farther west I drove the higher my milage went...So it may not be all bike, could be the gas as well.

Thanks for all the replies, I,m just at odd,s why this one gets such crappy M.P.G. I think it might have something to due with the low compression 122-130 which should be 185 when new. But it runs great. Safe riding to You All.

I get low 40's when I run on the freeway at 70-75, sometimes high 30's if going into a headwind. Mid to upper 40's If I keep at 60 and below.
Mine was doing mid to upper 30's and I found a bad float setting. Best I have gotten with my 86 is 48mpg. I use to be able to get 50-52 on a trip on my 85-A but then fuel was a little diffrent than now I think.
I would check the float settings again.....I know what a hassle. The only other thing is if someone changed the main jet size and or raised the needle in the vacuum slide.
Last time I did a copression check I think I was in that 140 range. Going to recheck one of these days, it's just that it runs so darn good.
Enjoy the ride. They are all good, just some better than others.

Thanks Mooseman for the float pointer, I guess I,ll pull the intake again and recheck the floats in a few weeks, The main jets and pilots are all stock that came with the rebuild kits. Thank all of You for Your input.

Last trip the wife and I took, about 200 miles, we averaged 43 mpg, neither of us is a light weight either. I thought the mileage was pretty good.

On my 1984 GL1200 I depending on if it is just me or with Mama on I can run from 33 to 40mpg. I run around 60mph. depending on speed limit. The faster you go, the more gas you burn up and traffic condictions play a big part too. Start and stop, speed up and slow down. On a straight cruise I would be happy with 35mpg. I can avg. 225+ miles a tank and thats with an extra 300lbs. Me Mama and what ever we take with us.
How many times do I have to tell ya,,, The right tool for the right job!

I get a little over 45 MPG riding 2 up on my 85 LTD, doesn't seem to matter much if I am doing a moderate 45 MPH on the Blue Ridge Parkway, or 65 - 70 slabbing it on the way back, averaged the same. Yet riding alone, it drops to about 43.5 MPG.

I have had mine up to 90 MPH for a short distance and I can tell ya, Gas mileage Drops DRASTICALLY :o

Never measured it and didn't have the balls to take my hands off the handlebars to hit the instantaneous button on the trip computer, but I would guess it was in the mid to high 20's MPG.

Maybe you just gave me a clue as to what I have been calling rot gut Texas gas. Whenever I go long distance, cross country i always check my mileage each tank as I go along. I have always said, once I get out of Texas my mileage goes way up. From San Antonio to El Paso, the speed limit is 80mph which of course means 90mph..so that's what i run most of the way....It drops to 65 or 70 once into New Mexico...a few other places up to 75, but most is 65 to 70.....Guess that really is the reason my milage goes up about 20%..Never really thought about it before, as my 75 wing I had years ago got 42mpg, no matter how I drove it and I drove it hard.

We rode up to the Blue Ridge Parkway yesterday and I waited till we got into Va to get gas, but that would put me pretty close to fumes, but thats ok. Immediately I felt an increase in power, the wing was so much more responsive to the throttle. NC gas with ethanol sucks!

ethanol is the biggest factor as far as mileage goes, the north east didn't see it until a few years ago. I noticed it when my old truck that usually got about 17 mpg on the highway was suddenly getting 13 mpg. The only change was the fuel, it now had ethanol in it. My winter project is to change fuel lines etc that the ethanol eats up. I never understood why the gov mandated ethanol, yeah, it's supposed to make things "nicer" for the environment but at the same time it's making us consume 20% more fuel to go the same distance .....

Don't think it had anything to do with the environment. It takes more fuel to grow the corn, harvest it, turn it into fuel than it saves as well as you said the lower fuel milage. The same thing happened to me with my Sierra, milage went from 18-19 to 15-16.

As far as I am concerned, it had to do with votes and pork....All the corn producing states are now owned by the present govt. Anyone with even 2 brain cells can figure out it is bad for the USA. Not only from the fuel standpoint, but the inflation it caused everywhere else in anything that consumes or uses corn in it food products.
