Mine sucks. I just picked it up used and it's bone stock with 6800 mi. I got 150 mi. on the first 6 gal., and it's looking like I can expect to see similar results from the second. 25mpg? That's horrible. Damn, my Wing was getting 40. Can I expect to see an improvement down the road a bit?

 

Did you check A/C? I thinl a clogged air cleaner would help kill the miles, something is not right. I would think it would be in high 30's anyhow.

 

Is your mileage City, Highway or a Combination? Is the bike performing well?

Assuming it's Highway mpg's your talking about: I've owned 7 Ultra Classics, including a 2011 and they've always averaged around 40+ MPG on the highway at 70 mph. I've also had two 1800 Goldwings and both of them consistently got 45 mpg.

Something isn't right and it isn't going to improve unless you find the cause. Your motorcycle may still be covered under the factory warranty. If so, take it to your dealer and let them check it out. If it isn't, there are a few things that you can check yourself: Air cleaner, spark plugs and tire pressure. It might also help to run some injector cleaner through a tank of fuel. I always use Chevron w/Techtron (black bottle) that can be bought at Walmart or most Auto stores (I won't go into a lot of details, but based on my experience, it is the best you can buy). There is also a remote possibility that there may be a problem with the catalyst in the head pipe.

These bikes are set-up to run very LEAN, in order to meet EPA requirements. A Stage 1 upgrade with a high-flow air cleaner, free-flowing mufflers and an ECM flash (or tuner) can help with fuel economy and performance.

 

I have had a 2010 and a 2012. Both of them got well over 40 on the highway and mid 30's in town. How agressive are you when riding? Are you keeping the RPM's lower ( you mentioned Wing and they spin a bit faster) and using all the gears? I mention this because I knew a guy that never used 6th gear because all of his previous bikes only had 5. Other than that, I would check to see if you have a dragging brake or something. Those MPG numbers are very poor.

 

my 2011 103 gets mid 30,s in the city and mid 40,s on the highway. but when i get on it hard in the city it gets mid 20,s .but i didnt buy this for fuel mileage

 

If it's still under warranty have the dealer look it.

 

So you didn't buy it for gas mileage?

Why would anyone purchase a "Touring" motorcycle unless there were some expectation of fuel economy and cruising range?

How much fun would it be if your Harley only got 15 MPG?

I've done the majority of my touring West of the Mississippi River and have run into many situations where it's been 150 to 175 miles between gas stations. I expect any "Touring" motorcycle that I've owned to have a cruising range of at least 180 miles, so I need to either buy a bike that gets descent gas mileage or have a huge fuel tank. I'll take the fuel mileage any day!

 

I'm still getting used to the EGC and I'm hoping that my riding style is part of the problem. I'm not a an aggressive rider at all, however, this EGC is not the Wing I'm used to. I try to keep the RPMs down by using the gears; even 6th when I can. I find that I'm downshifting more with the HD as the Wing is much more forgiving at lower RPMs and in higher gears. With the Wing I upshifted in groups of 2, rarely using 2nd and 4th on takeoff; 1st, 3rd, 5th. HD brakes seem to be good. It pushes easily around the garage. I still have a month left on warranty. I'll continue to watch as I run a few more tanks though it. If it doesn't get better soon it's off to the dealer. Thanks.

 

My '10 Ultra turns an easy 38-43 mpg but I don't run it hard at all. I certainly didn't buy it for fuel economy: I bought it for comfort and features. If fuel economy was the game, than there are a ton of bikes out there that don't weigh 900+ lbs. and can get double or more miles per gallon. I wouldn't be too happy getting 25 mpg, but then when I'm riding and the wind is in my face, I probably wouldn't care that much. Driving my Suburban at 11-15 mpg and my motorhome that gets 6.5 mpg (and far worse going up a long grade), the Harley is the easy fuel economy champ, even if it only got 25 mpg, though I would think a stock Electra Glide should do a lot better than 25 mpg.

 

The Goldwing Gods are very angry with you right now for buying a Harley. They probably cast a spell on your new ride.
