Big difference in gas mileage compared to GL1800

[Doug44]

Yesterday was the first ride I did with a close friend on his 2012 GL1800. I actually lead and we were on both 2 lane highways & Interstate. I lead a fairly spirted 193 mile ride before my friends low fuel light nessicaited filling both bikes. Here is where I was surprised he held excalley 1 gal more fuel ! It figured 38.7 for my F6 and 31.6 for the GL. Actually I was really surprised my bike did this good with the wind yesterday and running 75-78 mph on the interstate. The only thing I can figure is he has the stock windshield on his GL and it is all the way to the top stop. He is 6'4" and it looks like a sail his windshield. My F6 has the 13" Cee Bailey with the vent and Baker Wings below the mirrors which were open. You guys here have any similar results.

What year was the Goldwing ?

[flat6bagger]

Second sentence says 2012.

[vmaxed]

I see it now...I need a "coffee"

[Steve 0080]

It is about 75# heavier ....no to sure about the windshield making a difference...

[Pap]

His tour pack/trunk causes more drag.
On my other bike, I see the difference in mileage when I have the tour pack on compared to when it is off.

I get similar gas mileage on the F6B to my Goldwing:icon_cool:

I am running the 19 inch bagger shield and my new deluxe is clicking off the miles at 38 miles to the gallon with just over 300 miles on the new motor.

Got the opportunity for a nice 126 mile trek yesterday. Topped the bike off at the very start and finished with a fill-up of 2.77 gal. If my calculator is correct that's 45.48 MPG. This is the first decent ride since changing my air filter. Was previously getting between 38/42 MPG in sunny warm Florida. Might be the summer blend of gas here in North Eastern Pa. Have another trip planned for today so I'll be checking the mileage again. Hopefully I'll have the same results:icon_lol:

I found with my 12 Wing the MPG got better after 4k or so. I ran around 37, 38 most of the time. Less when pulling the trailer and carrying the wife and her stuff. I have averaged about the same with the 6. Hoping as the miles add up the MPG will go up a little. I filled up Sat and got 39.1 MPG

"New Motor" ??? What happened to the old one ?

[Texas TC]

I had two full Wings before my F6B, an '08 and a '12. I got a fuel milelage range of 38-42 pretty consistently on all three. My F6B tends to stay on the lower end of the range because I tend to ride it harder just because it is so much fun!

What do you mean Doug... his tank is 1 gallon bigger... or he needed 1 additional gallon than you did on this particular fueling stop?

I generally break 40 riding two up with the wife. I confess to not riding real agressive when she is on. The worst I've gotten is 35 on a 160 mile trip at 4 in the morning in 1 hr and 50 minutes. Generally riding by myself yields about 38 mpg. As for the windshield thing , you are correct. Bigger the shield less the mileage.

[edgeman55]

I go 385 lbs so I could be called two up alone which is the only way I ride now days.I am 6'5" with a 19" Baggershield up front.I have never gotten below 40mpg and best was 45 with a tail wind.

A lot depends on how hard you ride.

I thought this was common knowledge the gas tanks are the same capacity on both the F6b and the Gl1800

Yup, sorry if I misunderstood what you wrote.

IIUC the guy who makes that turbo kit includes a custom gas tank with it that's about 1 gallon larger; I've been tempted to give him a ring and try to get one.

I agree when I ride her hard she see's 40mpg if I cruise at 70mph she does 44mpg or so.I think overall these do great on mileage considering the size and weight of the bike.Plus after 200 miles I am ready to fill her and walk around for a spell.
