    I have a 2009 G650X Country with about 2500 miles on it. Great bike... EXCEPT... a while back, it started stalling when I'd start up in the morning (5x per week commuter). Usually it would run for 20-30 seconds, then stall suddenly. Start it back up... runs another 5-10 seconds... then stalls again... and again... repeat 5-10 times before it will finally idle without stalling. Took it to dealer and they replaced the idle controller. Problem solved! After that, no more stalling... until a few days ago. Now it's back to the same exact problem of repeated stalling after starting cold. If I try riding off without warmup it's subject to stalling despite my coaxing of the throttle... not nice (or safe).

    So I called the dealer again yesterday. They told me that BMW has this as a known issue, but there is currently no resolution. I'm probably going to bring it back to them again anyway since I'm under warranty. At least I'll get a couple of days of non-stalling loaner bike out of it.

    I have seen this "nuclear" option which resolved a warm-stalling issue:

    Anyone else having the cold-stall issue? Any resolutions?

    My XMoto just returned from the local BMW shop (4 day turn around, excellent for the summer season). It too was was stalling upon startup, tech found a frayed speed sensor wire going into the crankcase. He replaced, re wrapped, reset computer. Bike runs like a champ again :)

    my xmoto is in the shop right now for the exact same thing. they say its a pulse generator. which goes into crankcase(actualy by the stator
    )which may or not be what bike#8 had fixed(can you confirm) . anyway i hope that fixes it

    Hey satur9,

    My info came from the paperwork I received when I picked up my bike. I didn't get a chance to talk to the tech guy. I'm due back for my 6k service pretty soon. I'll ask then.

    My bike does the same thing. It is very annoying some days. It has done it from day one. I asked my dealer about it ,and he basically said deal with it. It doesn't do it every day so I've been living with it.

    your problem might be different from mine then. my bike used to start first time everytime even in 20 degree.(i ride in winter). it just started acting up. and does it everytime the engine has enough time to cool off.so basically to work and after work everyday for the past couple of weeks.

    you didn't get more impatient starting over time did you?

    if I start my bike before the idiot lights go out - i can produce the stalls so many people complain about in the forums...

    when I wait till the idiot lights fade before I start, I've never had it happen...

    I suppose it is unlikely that all these issues are based on impatience, but perhaps it is a clue to what might be causing all these issues...

    Messing with the throttle before starting and/or starting before the lights fade are often pointed to confusing the ECU. Flaking out batteries also seem to drive some similar problems.

    So I'd check your habit first just in case that is playing into it, then I'd check your battery to make sure it is giving you all the voltage you need under all conditions/loads.

    after that, I dunno... good luck

    My X-Ch recently started this BS also (around 3K miles). I haven't spoken to my dealer service department about it yet. Highly irritating.

    Thanks for the info. Yes... I'm up on the tricks... waiting for the lights, don't touch the throttle, etc. I have a new battery, too (was replaced under warranty as factory battery was weak). I've also read in other forums that switching to regular-grade fuel can help. So filled up with that on the way home today. If that doesn't work, next trick I'll try will be to disconnect the battery to reset the computer.

    And then back to the dealer if still no luck...

    I just bought a used X-Ch with 2400 miles and it does the same thing. Will not run more than 30 seconds or so when cold and then just stalls with a loud clang; very disturbing.

    i knew the tricks before i bought the bike.i read EVERY 650x post here before i got the bike. battery optimizer every night. its definately not operator error. and mine doesnt clang. just repeated stalling. other than that it fine.

    My stalling issue was completely resolved this weekend when I pulled the canister per the thread referenced in my initial post. Idles perfectly now. Silky smooth. Not thrilled to remove this device, but I could not live with the stalling.

    Thanks everyone for your thoughts and feedback.

    I see I have company! My 2007 G650 Xcountry has been having a stalling problem too. Bought it from my local dealer as a demo with 500 miles on it in May 2008. At first no problems. Well, the cold stalls were there but they were so infrequent that it wasn't worth complaining about -- but this season it's gotten worse and worse. Normally I have to restart 2-5 times. Once it gets going though it runs great unless I stop long enough for it to cool down too much -- then I have to start the process all over again! Ugh! Most of the time it just stalls quietly but every so often it stalls with a super loud screech. What's that!?! The starter? Dealer put in a new Yuasa battery about a month ago. I heard from a local X Challenge owner that a new battery solved his stalling problem -- but not mine! Still having problems. I read about SeaMoto's success with removing the canister and Satur9's pulse generator which I'll mention to my local dealer. I have just over 10k miles on it now but the 3-year warranty will expire in February 2010. Considering I live in Wisconsin and won't be riding in February, I'd hoping to get this resolved before the end of this year's riding season. Are there any other success stories out there? Anyone else still struggling with this?

    The other day I was getting the X Challenge ready for Big Bend and decided to check out my throttle body for dirt and dust. I run a foam filter but after doing the west side of the TAT what could it hurt just to make sure. I found a small amount of dust built up on the throttle body but I think that was still from running the old paper filter. Anyway if you look on the front side of the throttle body about an inch down there is a small hole this is the opening for the idle control device. It looked like there was some carbon build up in the hole. I cleaned it with a Q-tip and alcohol it took about 5 Q-tips to get it clean. Put the all back together and the stalling is gone. My stalling would only happen on the first start up of the day when it was cold. I did some other things to the bike but this is the only one that had anything to do with the motor. Maybe someone else can try it to see if this will resolve there stalling issue and let us know. Good luck!

    Can relate to the cold stalling problems with the 2009 G650 x-country. I had mine back and forth to the dealer a number of times trying different things. I bought a new battery, a battery tender to keep it charged, only buy brand name 91 octane fuel. All these things helped, but it still stalled when cold or ran lean. The dealer was out of ides. I called BMW customer service finally at the suggestion of the dealer, since BMW had not suggested anything that worked either. Finally someone at BMW suggested downloading the G650 gs download into my g650 x-country after getting some pressure from customer service. To do this required some trickery, but it seems to have worked. It is four weeks later and I have not had a stall and when cold the bike does not run lean. Along the way the tech at the local dealership also found an almost ready to fall off terminal lug on the positive side of the battery. He soldered it for a secure connection. Hope this helps.

    Part 6 on the diagram is the idle air controller. It can get a bit bunged up with muck causing idle issues. Best bet is to remove the throttle body and the IAC and clean the end of the controller and the idle port with carb cleaner and cotton buds.

    The pulse generator is a separate issue, caused by metal particles from the starter clutch shorting out the pulse generator. This may mean that the started clutch also needs replacing.

    Yes, the problem still exists. Now that the weather is cooling off here, it's a daily hassle, and BMW's customer service on the issue hasn't improved. I'm bumping this thread to raise awareness for those contemplating buying this model, and also continuing to try to work with my nearest BMW dealer to implement some of the ideas suggested here!

    I had the exact same thing and now my bike runs perfect everyday. Fix it - you will love the bike afterwards. Here is what fixed it for me:

    1) clean the idle actuator and throttle body with carb cleaner (mine wasn't very dirty) - then run Seafoam through a few tanks of high quality ethanol-free gas to finish the cleaning.
    2) remove the charcoal canister - google G650X Canisterectomy or similar to find instructions. Do it, don't worry about the warranty.
    3) Install Leo Vince X3 pipe. I use the quiet insert.
    4) reset the throttle body with the key on / key off full gas maneuver - Drone knows the exact procedure.

    My bike has run perfect every single day since these changes and was a real pain in the ass, especially in the winter, before these changes.

    The other things that greatly improved the bike for me were removing one of the throttle return strings (there are at least two - this is where the throttle cable ends, use a needle nose plier to remove one and leave it loose in there) and finally - replacing the stock grips.
