'15 CVORGU. Why am I getting less than 200 mi/tank? Anyone else experiencing this? Got a buddy with a '15 RG Special getting the same crappy mileage. All the bikes I've owned and it's never been this bad.

[GregKhougaz]

The short answer is you are riding a 943 pound motorcycle with lower fairings that are aerodinamic bricks. 

How many miles?  How much fuel are you adding each tankful?   My milage got better until about 3K miles.  A Stage 1 kit from Fullsac helped.  There are a plethora of other factors: Your weight, riding style, tire pressure, trip distance, etc.  I get just over 40 mpg but it varies.

Thanks for the input, Greg. I'm not riding it hard. I came from a '12 CVOSG which had lowers & I was getting 40mpg. I first figured the weight diff had something to do with it, but my bud's '15 RG (no tour pak, lowers) has to compare in weight to my '12 SG, if not less, and he's getting the same bad mpg. I'm a little over 1K mi & he's close to 2K. None of my bikes have had this bad mpg - even out of the box. Could it be a bad dyno-tune by the dealer?

[GregKhougaz]

200 miles / tank but how many gallons?  5 or 5.5? That would be a 10% difference.  Did the dealer put it on the dyno?  Since you didn't say, I assumed your bike was stock. Modifications can make great differences in milage as can the subsequent tune.

It's mostly due to the tuning.  My buddy's 2011 FLTRUSE gets 240mi per tank almost every time and he weighs 280lbs and carries a bunch of junk in his bags and TP.   That is even with the occasional fun twist of the throttle when we get bored.  If he runs hard for most of the tank it does go down but I don't think he has been at less than 200mi per tank much at all.  No the bike is not running lean either.   I can get 230mi per tank on my 120" but if I ride hard it goes to about 180mi.  If you have not had a good Dyno tune on the bike you will be amazed at how much better your bike will run if do.

I'm usually putting ~5-1/2 gallons in at 180 mi. That gives me a little over 32mpg. The dealer did the dyno, but after another dealer saw the printout, he was less than impressed with the results. I'm going to have it redone by a different dealer over the winter.

[fxsbsefox]

Thanks, RGKen. Gonna have it re-dyno'd over the winter. I'm hoping that does the trick. I appreciate all the replies.

For the life of me I don't understand why so many people still go to their Harley dealer for tuning.  The vast majority of H-D dealerships DO NOT have a fully competent tuner on staff.  Most truly good tuners wouldn't work for the typical dealership.  What most people get from their dealer is a canned map with a few runs on the dyno to make them believe they got a "dyno tune".

Do yourself a favor and do some research on full time professional tuners.  Even if the closest one with a great reputation is a hundred miles away, the trip will be well worth it versus another lousy "tune" from the dealership.  Ask some of the pro's on this site for recommendations for people in your geographical area.

^^^Completely concur.   Luckily we have a local dealership that has 2 really good tuners.   With all this being said though; the only thing I care about is that the bike is tuned right and runs like it is supposed to.  If that means it gets 25mpg I could care less about that.  I didn't buy a 900lb touring bike to get good gas mileage.   Everyone is different in what they look for.

No tune, right out of the box/crate, my '15 has been averaging 240 to 260 miles on the range to empty computer and has been fairly accurate after 6,000 miles.  Over the almost 6,000 miles, I've calculated an average of 40.8 MPG which takes into account a bit better on highway/slab trips and a bit less for around town/work to home/curvy road trips.

A good tune, as opposed to someone just running it open loop and rich enough to pass raw gas out the pipes, wouldn't result in 25 mpg or even 30 mpg.  Contrary to popular opinion, a truly good tune doesn't mean living with an inefficient engine.

A good tune isn't a Harley dealer loadin' a canned H-D "map" and then makin' a run on the dyno and here's your printout.  You should have been asked stuff like what RPM range you want the power, what cruisin speed you run etc., etc.  The he'll make a map that fits your profile, my bike had fifteen runs on the dyno to perfect the SWEET outcome of peak torque at 2800 RPM's 40 MPG at 79 miles per hour, not to mention the burning of thighs gone.  All my "mods" were a Fulsac DX and 2.5 Fulsac baffles, oh yea changed out the Screamin Eagle spark plugs for stock one.

My 15 Street Glide does 370km from full to the light on, that's 229 miles for you imperial guys. it doesn't see more than 4500rpm very often and i don't chug it around.
It has slipon's only.

Slower riding under 60 mph I get close to 46. On the freeways when the wind resistance kicks in I get about 38. Now also keep in mind I had my speedometer calibrated as Harley has a habit of letting them read too fast by a few percent. I think Steve (Fullsac) told me mine was 5% high so whatever gas mileage you think you are getting you can probably reduce it by about 2 mpg or so.

I think most of us are about ready to stretch the legs a bit after 200 miles so it works out okay for me.

You completely misunderstood what I was saying.  I meant if that were the norm I would still have what I have.   If I wanted a bike that gets great gas mileage I would shop around for that.  It was just an example.
