Went for a ride with Uncle Charlie, we did 248 miles, I used 5.1 gallons. He doesn't like to do much more then 65 or so. I lead the way out, he lead back home. It was a nice combination of county roads and highway. I've got Dale Walker slip on's with a Power Commander map loaded specific for them. It's the first time I really looked at the bike's mpg. I'm impressed to say the least.

 
I'm a hypermiler, but saving gas is not a priority when I'm riding. If you check out www.ecomodder.com there are some guys getting crazy gas mileage out of 250 Ninja's and CBR 250's. Some of them are running tail fairings designed by Craig Vetter ( www.craigvetter.com ).

Driving or riding for fuel efficiency can be as great a challenge as anything you can do legally on the road. I'm still on my first tank, so I looking forward to seeing where I come out.

 
FWIW I got my FJR in mid march and have averaged 45 to 49 mpg over 6400mi. Most of my riding is commuting so I go from blasting down the highway at 85mph to stop and go traffic. The best mileage I got from a tank of fuel was on a weekend ride with some "spirited" riders. 255 miles 4.95gal. :yahoo:

I have been more than pleased with everything about this ride and the fuel mileage is an added bonus

Screw the milage, twist your wrist. Why does anyone buy a rocketship and drive it like a harley ???????????????
The great thing about the FJR is that it does everything well. It can go fast or slow as the rider's mood changes. It is as comfortable grinding footpegs as it is pretending it's a Harley. There are times the throttle is used to compress space and time, there are times it's fun to just ease along. It is nice to know that the rocketship can be economical if you need or want it to be. Dad's best tank was 50.1 mpg for a very enjoyable day ride doing the speed limit. Normally mid 40 mpg range.

 
To me it doesn't make sense but time and again on long trips via open rather straight roads I get upper 40's MPG and some times 50 MPG when cruising between 70 and 80 MPH. I typically get low to mid 40's cruising at 60-65 MPH. Must be the fuel mapping but I don't really know.

Same MPG figures here.Just went on the Adaks ride & hit 50 mpg on several fillups! Ran all backroads to & from. Best MPG I have seen! A good excuse to stay off the interstates.

Well stated above on both of the quotes. Naturally I would like to get good MPG, but it is not my first priority. Good thing... I only get MPG in the hight 30's due to riding in SoCal traffic and higher speeds when I can break free fo it.

 
I seem to get the best mileage when I am out on highway and in back country - averaged 46 in 700 miles in WV the other weekend. My commuting mileage, which incldes all back roads and some stop signs is more like 42mpg. Seems like the bike almost doesnt care if I am 4th or 5th and if I am behaving myself or scrubbing tires.

 
Picked up 61 mpg at 5 to 10 over the posted speed limit in northern CO with a 25 mph tailwind with even a few spirited applications of acceleration.

Also, as mentioned, when coming across SD and facing a 30 mph headwind and rain at 75 to 80 mph the FJR only could muster low 30's.

Wind, elevation, rain, windshield selection and speed traveled all have an impact on MPG.

 
Funny y'all are talking about MPG, I just logged my worst tank ever in 2,500 miles this weekend. I'm using the Moto Minder iPhone app (great tool BTW and worth the price) which recorded 27.54mpg. :eek: This was a very windy day, riding 2-up with cases on, and all twisty country roads (113 miles was M-22, great bike road) with plent of happy throttle hand. While I was surprised by the low figures, I can't say it's unexpected considering the conditions. I'm very happy with my average of 41.31 mpg since much of my driving is city and stop 'n go.

 
It's all about altitude and the ECU running leaner due to less air in the mixture. I run above 5500 feet above sea level and get 48/ 49 mpg all the time. While it doesn't run like it does in lower elevations. I really don't notice the difference, it runs good enough for me! :yahoo:

 
I have often wondered WHY does the FJ get better mpg at altitude and hot weather. This I'm convinced of - FJ's get better mpg when the air-fuel mixture is richened-up. So why does the mpg take a **** on a cold day. I think the ECU is programmed to assist in maintaining a constant engine temp. On a hot day it richens the mixture. Conversely on a cold day it leans out.

 
I seldom use my bags but my speeds are usually above 70. My average is also around 44mpg. My best tanks were at 48mpg.

Gutted headers and a box mod is about it.

 
Yes, mileage is better without the saddlebags. Mine is about 2.5 MPG better average.

Mileage is better in hot air and high altitude because the density of the air you have to push out of the way is less therefore requires less energy to move out of your way. The effect of temperature and altitude on your stoichiometric ratio is negligible if your ECU is working properly.

Good job at 48.6 MPG.
