    Hi All.
    Sold my gsxr and picked up an 07 adv 990 with less then 3000 miles on it, pretty clean bike + a bunch of extras yada yada...
    It has FMF adv silencer set and a dynojet power commander. While riding it today the bike has been stalling quite a bit also, upon downshifting and slowing down there is a backfire like sound.
    Is it normal? is it my riding style? WTF?
    Today was my first ride on the adv my riding background is limited to powerful sport bikes(liter and up). Before I freak out and go cry at the dealer any word of advice?
    Also the bike came with an extended warranty, If needs be how do I transfer it.
    Thanks you all

    Search around and you'll find a few bikes that do this. They don't all do it (mine doesn't) but a few drive their owners crazy with it.

    Most certainly transfer the warranty. :nod

    My local dealer did my warrany transfer on my 07 990. The fee to do the transfer was $25.00.

    Good luck with the new bike.

    I would try having dealer re-flash back to stock map. I dont know about FMFs but my WINGS with "quiet inserts" do not need remapped. From what I have readm on this site re-mapping from stock creates more issues than it solves. Im a fan of keeping the stock map for varity of reasons but to each his own.

    I posted this on another stalling thread.......

    Quite a few folks have gone round after round with KTM on this issue. The explanation from KTM is similar to this from the HOW

    Engine stalls when clutch is pulled in ~5,000 RPM:

    The fuel injection computer shuts off fuel to the injectors when the throttle is closed at 5k and above. This can cause the engine to stall if the computer doesn't sense the clutch is pulled in at this time.



    Andreas Berner, KTM Factory Rep: "When you pull the clutch, do you have one or more fingers behind the lever, and what position of the lever adjustment do you use?
    Because there is an electrical switch telling the ECU that the driver pulled the clutch lever and with the lowest position of the lever and a finger between the lever and the handlebar it is possible that the switch is not activated!
    So the ECU doesn´t know that the clutch is open and can not react by giving the engine enought fuel for idlespeed, this can also cause a stalling engine and is very hard to detect for the dealer, because there is simply no "failure".



    However, I have bypassed the clutch switch, taken out the secondary butterflies, and bumped up the idle to 1600 and I still get the stalling. Running stock map with stock pipes, or stock map with akra pipes with the insert. Oftentimes it will be accompanied by a low idle condition where the bike will sputter at around 500 to 1000 rpm before it dies. the ECU has been flashed numerous times with various maps to no avail. ECU replaced, fuel pump replaced, ignition system replaced, you name it, nothing has fixed it so far. It obviously has to do with a low fueling condition when rolling off the throttle but I'll be damned if I know how to fix it. KTM has no idea either FWIW.

    It seems as though the condition gets worse with time for some reason. First it only happened about every 500 miles of riding, now it happens several times in a day ride.

    If you figure it out, let us know....... :rofl

    I have an 07 990 with about 13k on it and no stalling or idle problems yet. I am also running the Akra pipes with the factory map. Just as many have said there have been no problems running the Akra's and stock map.

    One think I have learned over the years is, GROUNDS are very important on any computer control system, car or bike. Start with checking all your grounds. Do this with a good meter. One that deals with mVolts. Do a voltage drop test. To do this put one test lead on Bat. neg. and the other end test all your ground wires. Start with the grounds on frame but also check what grounds you have going to your ecm. You have to have it running to test. You may see something in the range of 5 mv to 50,75, maybe even 100 mv. But never anything 200 or so.

    It might be hard to understand if you don't do this all the time but it is the first place a tech should start. Rule number one.... Check powers and grounds. If you don't have a good ground voltage will start to climb on that wire. The computer uses a lot of low voltage reading to do its job. Oxygen sensors run between 1/10th a volt "lean" to 9/10th's a volt when reading "rich". So you can see how just a little voltage could cause problems. If you want to try this but don't understand it, just shoot me a pm with a number and I can explain much better than trying to type it here.

    Spent some time at the dealer yesterday, I have printed out all the info I got from the tread and gave him a stack of paper to go over, he was a bit annoyed but had to endure in order to satisfy the costumer. In any case they think it was a faulty side stand sensor, no stalling on the way home so I am optimistic, Time will tell.

    By the way his major advice of the day was "stay away from the forums" . A bit hostile, don't you think?

    ...about 98% of the Dealers are sharing his position---sometimes rightfully so, sometimes to the detriment of you/me/us not dropping another minute, nor dime in their establishment.

    ...most of these flaws aren't gonna be found by a motojournalist that gets a "short/long term loan" bike from an OEM, but some Joe Lunchbox that dumps the funds and enthusiasm on a particular bike only to only be beset with an onslaught of ails...surf the forums, take note, document your progress and hold them to what the warranty covers---that's your right...

    ---hopefully it's a minor issue that can be nailed. Mine wasn't-but my new 990adv has been 100,000,000 times better than the first 990adv I had...good luck!

    Seems a lot of bikes in the 07 year are stalling now. Taking the bike into a dealer for me is a freaking headache, costly and a hugh inconvenience to the other person I have to get a ride back from. So, when I take mine in for the first time, I'll shove everything I have from this forum in their face, and they will only have one opportunity to fix this problem before I start raising total hell with the factory. KTM knows this is an issue world wide now and they need an immediate recall before someone unfamiliar with handling a stalling motorcycle gets injured or killed.

    ...the best vindication I got from all my stalling heartache and hassle was giving the KTM rep the keys to my 990adv, "...dude, trust me it'll stall out on you..."

    And sure enough it did when he was making a left against on-coming traffic...and wouldn't start again after that. He was whiter than most sheets in my house-when he was pushing the bike back...

    ...they know about it-trust me...

    Finally... a month, 3 dealers and endless hours on the phone and the forum, the tech over at Marina KTM did me right!
    He determent that the FMF pipes need to be on the euro map, than he tweaked the power commander to perfection, It feels like a new bike!!
    I guess sometimes it's all about a tech that gives a shit to spend the extra time and effort and be creative with his approach. The bike was there over night, tested and retested and they did not charge me a dime!
    Thank you all for your support I will be hitting the road very soon.

    that seems like the place to start right after checking connections. Not too difficult with PC or tuneboy to add fuel to the idle/ bottom end and low angle throttle openings. I think the good dealers have a tool now that lets them do that . Certainly that would be a better place to start than ripping out the ecu,ignition system etc etc

    I have a 2009 990 and this sounds like the same thing that is happening to mine, except I don't have to touch the clutch to stall it out....just give it a quick burst of fuel and then it will stall out.

    Any suggestions....
    It's been in the shop for over a month now and they can't figure it out.

    The posters in the 2009 thread were commenting on their stalling problems when the throttle was abruptly shut off at 5000+ rpm. A known problem with the way KTM handles emissions. Your problem, with stalling when the throttle is open suddenly is not likely related. However, it definitely isn't normal for a 990 to do this. Does it happen every time you whack the throttle wide open (cold or hot, from idle or at all rpm, up hill down hill, after coasting)? Does it die completely, or is it a flat spot?

    Like CP said, you problem is different and definitely not normal. Does it stall completely? My issue was when pulling in the clutch to shift, and not even close to 5000 rpm, the engine would stall completely or hang at a low idle condition around 500 rpm. Probably an issue related to the way the system works, but I never figured out exactly what was causing the problem.

    First thing I would check would be fuel pump, or clogged fuel filters as well. If youre hitting the thottle and the bike coughs, sputters and has zero power, that is most likely clogged fuel filters IMO.


    Just to update my own experience with stalling. Over 2 years ago, I put in another fuel pump (warranty) put on a 2 into 1 exhaust, latest version at the time of the stock fueling map, and my bike never stalled again. So I dont know what was wrong, but the problem has been gone for 50,000 miles so far.

    Good to know your final outcome cm. We've had a few reports of bad ECU map flashes straight from the factory. Looks like the SOP for stalling issues might be to re-flash, then try a new pump and or filters.

    I did several things at once including the 2 into 1 so I really dont know what cured it.

    I know that they threw every part and ECU flash imaginable at motosoto's bike over the course of many months, and it never fixed it. KTM actually wound up giving him a completely new bike but it cost him a lot of time and effort to even get their attention.
