Big difference in gas mileage compared to GL1800

[ths61]

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.

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

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!

Here is where I was surprised he held excalley 1 gal more fuel !

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.

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.
