Default Gas Mileage??

I notice that when riding 2-up I get about 135 miles on a full tank of gas. FOr some reason that just doesn't seem right, anyone have any suggestions other then riding style, I do not think it is my style of riding since I just cruise usually about 5mph over the speed limit and am not gunning it from the lights but rather just start off like normal.

Thanks in advance for any help

I have a '02 fat boy carb'd.

That does seem to be pretty low.
I've been getting about 42 mpg

Sounds very low....

Fuel economy is usually based on 3 conditions, the bikes state of tune, the type of conditions in which you ride, and your personal riding style...

Take being said, I live in a very rural area where there is very little (if any) city or stop and go traffic, and I also realize that Harley's aren't race bikes so I do very little full throttle runs which eat up fuel economy.

My 2003 EFI FatBoy has a Screamin' Eagle Race Tuner and has also been dyno tuned by someone that knows what they were doing..... The Softail runs perfectly, has plenty of power, and on runs averages right at 48 MPG.

i was getting about 40mpg's before i got it tuned over the winter. i was told that it should do alittle better since it's tuned but been to cold and nasty outside to find out. and i will admit since i do have some goodies in the motor i do open it up and it does go over 120mph's sometimes

So there is definitely something off.

Where would be the best place to start, I would much rather do the work myself if possible, although I am very new to bike mechanics, and very rusty on mechanics in general since I have really done any work in like 10+ years

Or should I just suck it up and take to a shop.

Thanks again for all the advice

Like OBAMMY said during campaign make sure tires are inflated to correct pressure. I know you have checked to see that your AC isn't clogged or dirty but other than that not being a Tech don't know what else you can do besides taking it to a reputable dealer if you have one in your area. I get between 40--42 mpg solo with luggage at 65--75 mph. Once in a long while at lower speeds I have gotten as high as 44 mpg but very rare. I also stay away from Ethanol as I lose about 4 mpg running the same speeds.

My carbed 99 Heritage dropped the mileage lower than it should have been and while investigating I found the plug wires had deteriorated pretty bad. Changed them to Sumax wires and got the mileage back up again. Time for a tune-up? Plugs and wires are pretty easy too change.

I have a standard 08 Dyna super glide only thing I hve changed out are the exhausts, the bike does have the 6 gears and EFI, I have not changed my mapping or added filter and I normallly run 50-55 mpg, on the open road and 45-50 around town, most of my open road is 70-75 mph, and i am not that easy on the gas taking it up to the rev limiter on occasions, I have had this type of consumption since new,
