    Dropped the bike off this morning with Honda Hollywood..managed to borrow a friends car so i wouldn't be stuck for the next couple of weeks while they are taking it apart and performing surgery and waiting on parts from Germany..meanwhile an hour had passed since i dropped the bike off...and it was fixed!!!!! All covered by warranty..turns out Lior was right..because the bike had spent so much time sitting (the last owner barely got through a quarter of its first tank) the gas had gone bad in one of the pipes..when starting the bike..first time..no battery lights..its starts up clean and looking like it should have....I was so thrilled to get it back and to feel like the unknown issue had been resolved such a relief..thanks for everyones input..

    Remember when you put a battery on after being disconnected or dead, you need to turn the key, turn the throttle from idle to full slowly THREE times for the computer to reset the throttle position input...then start the engine.

    In the OEM repair manual which apparently Ayrshire Bull has never read :evil

    However, the magic "three" in the previous post is not part of the process. The RepROM states:

    • Connect the lead to battery positive terminal (4) and install jump-start adapter (7).
    • Install protective cap (8).
    • Connect the lead to battery negative terminal (3) and install screw (1) with washer (2). Make sure that the connecting cable is routed correctly.
    • Switch on the ignition.
    • Without starting the engine, fully open the throttle once or twice, so that the control unit of the BMW engine management system can register the throttle-valve positions.
    • Switch off the ignition.

    Note that it says "switch off the ignition" not "start the bike". I don't know if that is important or not. Oh, and the "jump-start" adapter is a longer screw for the positive lead of the battery. I don't have it on my '05.

    Also, nothing is mentioned in the owner's manual on this procedure after reattaching a battery. I think if you do nothing (as I have done several times in the last month of tinkering with my electrical farkles) the computer relearns the throttle settings on its own. I have noticed no degradation in performance so far.

    However, it may be more beneficial for the prior to '07 models.

    YOU HAVE GOT TO BE KIDDING ME!!!!!

    My bike literarily just cut out at a traffic light as it was going green. Tried to start it and it wouldn't. This is the 2nd breakdown on this bike in 2 weeks?!!! the gas meter says 50miles left which is weird cause a few miles ago it said 72 (but maybe that's because it was downhill?) anyways my gf is on the area so she is going to bring me some gas which is what sounds like the issue but come on I thought this bike was meant to go across the bloody world. How am I gonna pack my bags when I am not even sure the bike will get me across town.. I have always had REALLY good luck with bike with MUCH more miles than this one. Has my luck finally turned?

    Do you use the trip meter between gas fill ups? I start looking for a gas station around 250 miles on the trip meter. Don't rely on the miles to go computer read out.

    250? On a GS, not a GS ADV? To get 250 I'd probably be walking the last 10, and that's on a good tank full. My "reserve" light comes on anywhere between 130 and 200 miles depending upon speed, wind, and elevation. 190 miles is typical. 130 was fighting a headwind in the desert while riding at 85 MPH.

    When the light comes on it usually reads about 40~44 miles to empty. The tank nominally holds 5.2 gal.... I once put in 5.1 gal with the miles to go odo saying I had 12 miles left to empty. Either I over filled the tank by a lot or the miles to go was over estimating.

    such a relief..my gf came with some gas , we filled up and she started right away..she was out of gas! and the computer said i had 52 miles left?! thought i would take it in tomorrow to find out if this is some other side effect of the sitting around gas issue...thoughts?

    Google "BMW Fuel Strip" which I think your bike has.

    Luke I am so sorry to hear that you are STILL having issues with this "brand new bike" ... Since you said it sat for 3 years (which is not good on anything) you might want to drop it off at the dealer and have him go THROUGH IT ALL, make sure you tell him that it did sit for 3 years (although I'm sure they already know you by name by now ...) so they'll know what to look for and hopefully you'll be trouble free ... I can only imagine the level of frustration, getting a great bike and going through all these headaches ... Once its all resolved you'll have a blast and we'll finally be able to hook up and RIDE ! ! ! Now I understand why I have not heard from you, I did not know you were still dealing with bike issues ... Good luck and patience WILL PREVAIL !

    I now have a 2012 R1200GS and the dealer informed me that this was one of the things they changed in the design; that the GS no longer uses the strip as a sensor for the fuel level in the tank. Not sure when this change ocurred but my guess is 2010 model year and later models do not have this issue to deal with...
