    Hey everyone,
    I'm the new proud owner of the 2011 KTM Adventure R. I traded in my Super Duke for this bike, and let tell you, It's absolutely the best bike i have ever riden. I added the Evolution Akrapovic carbon fiber pipes with the Euro mapping on it, and I am curious as to how many miles i can go on the reserve. I get about 130-140 miles on a full tank but dont know how many miles i can go on the reserve. On my Super Duke I was able to get 20 miles on the reserve.
    Does anyone know and can help??????

    I average 38 in mixed driving on my 950. A little less in the city, 34/35 ish. Lower in agressive off-roading (~30), and the best I got was on a flat stretch of tarmac that I did a constant 63 MPH actual, 70mph indicated for a couple hundred miles which gave me 42mpg.

    If you want an efficient bike, don't buy an LC8 :deal :lol3

    The most I've ever put in the bike on the centerstand was 5.7 gallons. I believe the capacity is 5.8 or somewhere around there. I can usually get 200 miles before running out of gas unless I'm bombing down the interstate at 75-80mph for the whole tank which shortens that up. The most I've put on the reserve was 58 miles when I was going through a couple hundred miles of 55mph canyons/mountain driving (marked at 35 mph speed limit :evil), but I get nervous after about 35 miles. The reserve is approximately 1.2 gallons or so I figure.

    Oh and for what it's worth I carry 4 liters of extra fuel in bottles on my soft bags but I've never needed them when I pushed the stock tank range over the last 15,000 miles and many trips out west where there's not many fuel stations in some areas. They gave me the confidence to do so however, as I wouldn't want to push it and get stranded without the extra fuel.

    I have a `10 KTM A990, I have about 6K on the clock, commute about 40 miles per day in mixed traffic, heavy on the city side due to stop and go traffic, I average about 35 mpg on the KTM, considering my ecoboosted F150 averages about 18 in the same conditions, I am pretty happy with 35.

    Interestingly enough my 09 Victory Vision, weighs nearly twice and much and makes nearly twice and much torque, and has an engine nearly twice the displacement, gets about 45 - 50 mpg in the same conditions.

    And I ride it like I stole it. I am easy on the accelerator in the truck. But the KTM and the Vision are rode like they did something wrong.

    I just purchased a 2010 990R and the fuel light comes on at 225kms. The bike came with Akra's, but how would I know if it has the right mapping?

    Highest milage 68mpg out(downhill with crosswind), 50mpg back uphill. Average 58mpg. This was with NON-ethanol fuel.

    To get that I used a 17th front.
    Closed loop fine tuned.
    Bridgestone Battleaxe street tires.
    07 S but with the gel seat to keep lower behind the windscreen.
    CPR air filter, custom exhaust, SD cams.
    Bosch O-2 sensors(thanks Cyborg).
    Speed limits were 50-55mph.
    185lbs street clothes 5'10".
    Back pack on and tank bag. No side bags or trunk.
    Leaning on the tank bag alot to keep Aero up.
    Never below 4,000' elevation.

    Lowest milage was years ago before I tuned my own maps. Akra map off-road with alot of sandwashes. Fuel light before 100 miles. Something like 25mpg can't remember.

    Usually average 52-55mpg highway and 45mpg off-road.

    The difference between riding 60mph to 75 mph fuel flow doubles in GPH rate. Measured with FAA approved fuel flow meter. This would very depending on your fuel map.

    Higher elevations have less air pressure=less drag. A/F ratio should stay the same. That's what the O-2 sensors are for.

    Currently working (very slowly)on re-mapping for 10% Ethanol. Have to richen from 14.7 to 14.1. to achieve Stoich with Ethanol.

    2007, 990A, FMF Q4's with 34,000 miles

    Before I put on the Q4's I was averaging 38 mpg
    After the Q4s I am averaging 33mpg


    I downloaded a fuel log app onto my smart phone and have been logging my fill ups for over 12 months now.

    Overall I am averaging right around 35mpg
    My worst was 21mpg (big knobbies off road with lots of sand) :evil
    My best was 47mpg (two up loaded with camping gear, I ride very tame with the wife on the back)

    It's all in the wrist...

    leaned out ak map. Isn't perfect, but it's getting somewhere.

    Not too lean, no abnormal temperature rising. Not as much powerfull as the stock ak map, but definitly not as much tirsty.

    So... how do I go about checking/adjusting these maps?

    Some have a link with more info?

    I've heard/read a lot about 990s high fuel consumption and was a bit worried when I bought my bike. Fuel usage on my 990 Adventure R 2012,800 miles,raw engine, run in according to manufacturers' advice but more on the aggressive side ,mixture of town,countryside and motorways.... 48mpg - 5.9l/100km.Can't complain :1drink.

    Check the "TuneEcu - Got tunes?" thread in Orange Crush, plenty of info and tools available. Carefull it's apowerfull destructive tool, don't go changing things w/o thinking enough of what you're doing.

    that's 40 mpg (US), which is considered fairly normal for a bone stock mixed ride 990.

    Still need to continue to refine mine. ain't there yet.

    It's in Tuneboy format. Won't work with TuneEcu. Worse yet, I can't seem to find the best one. Didn't back it up and my lap top crashed:baldy. Currently going thru some TuneEcu ones and will have to fine tune one of those.

    You milliage is also hope inspiring. We have all the time in the world for a nice running map.
    Thanks.

    I have 19/17 wheel set up , been riding mostly pavement with some lite dirt trails and my light goes on consistently at 165 miles. Although today I left the garage with the fuel lite on rode 24.3 miles stopped for fuel and put 5.3 gallons in :eek1 with a total of 203 miles on that tank. I've done it before when the bike was brand new with a total of 226 miles on the trip meter for that tank of fuel. I do have a roto fuel cell, but like knowing my limitations :) 2010 990 R

    Sorry for bumping the old thread...

    Do the Bosch O2 sensors actually make a difference? is it worthwhile to replace the OEM ones?

    Again, apologies for bumping an old thread...

    I've just filled my (2012) 990A for the 2nd time since getting it. It took 15.8 litres, with 177 miles from last fill up (fuel indicator came on at around 165)

    I make that 3.475 gallons, or 50.9 mpg. Seems more than reasonable to me!

    My bike is absolutely standard (at the moment!), 100% road riding, mostly between 50-80mph

    I expect that with this kind of riding, it should be possible to get 200 miles out of a tank
