    Having never looked at the attachment points on the cam/camchains, I am surprised they can "move" at all. Are they not locked in place with a woodruff key?

    Another quick update: BMW SA have requested that my dealer investigate the cam tensioners as they may be the cause of the problem, I am just waiting them to request I bring my bike in. The case continues.

    On the 22 of May my bike went in and had the cam chain tensioners replaced. This was because the cam alignment kept changing and these tensioners are common between the 4 cams so they suspected the tensioners. Nonetheless the misfire/pre-ignition/detonation problem persists. To the point where again today when it stalled on me I was almost taken out by the vehicle behind me.

    Below is a video clip where I can demonstrate to you what happens if I twist the throttle very slightly off idle. I was able to replicate this a few times to some colleagues at work. I did turn the ignition off and on to reset the computer and it still behaved the same. Listen carefully to the engine idle while watching the rev counter, you will hear the erratic idle and pre-ignition (and ping) and then it stalled. :eek1 I did not change the throttle position nor touch any switches.
    I don't know if this is related to the same issue as when I blip the throttle before I engage gear but it's not right. :dunno

    So in the video, was that a idle, or where you holding the throttle slightly? I'm sorry, but it wasn't clear.

    That definitely does not sound right if the bike is at idle and fully warmed up.

    I bought a bad tank of gas that made my '11 GSA run like crap; mostly at idle and during acceleration. I thought it was a stick coil, and even took it to the dealer, who found nothing wrong. I siphoned the remaining fuel, refilled at a different location, adding some Seafoam to clean it out, and all was good.

    Hi Stan, it is a very light turn on the throttle, probably 1% of the full twist, just off idle. I had just come from a ride where it again stalled as I blipped the throttle at a traffic light as it turned green, I was not in gear yet even, engine was warm. I don't know if this is related to when it stalls as I blip the throttle though, symptoms are the same, pre-ignition and stall.

    I have done almost 15 000km's and this problem still persists, unlikely to be a bad tank of gas :evil

    Something to check if you have a buddy that has a bike that doesn't show these symptoms is to swap coil packs. (all 4)

    I have a '12 12gs w/ 500mi so far and I too blip the throttle before starting off from a stop. The throttle blip occasionally causes the bike to choke and it stalled 2 times during my last ride. Glad to hear it is not just my bike or riding style, but definitely not happy that I have to accept the fact that my new bike will act like this without explanation. WTF. If the bottom line solution is to change my riding style, then I guess it's a cheap fix.

    I've read reports that say no, on the camhead they are not. Find it kind of hard to believe.

    In your case, pull the connector from the coil, tape it up, and go for a ride. If there is no change, it is the stick coil. If there is a chenge, try the next one.

    See the connector? Lift up gently on the tab and pull the connector loose.

    Some more feedback,

    I just returned from Donford Motorrad, BMW HO requested I take my bike there for an inspection. Neil Berry was kind enough to loan me a 2012 GSA while they inspect mine. I can report back the following,

    1. The average fuel consumption indicated on the Donford GSA is 5.9/100km this is what mine was before they loaded the new software now it is 6.6l/100km
    2. The Donford GSA has more power, at least my butt dyno tells me that
    3. The Donford GSA also pings when riding at 4500rpm (+/- 125km/h) and I accelerate quickly
    4. The Donford GSA also detonates/pre-ignites/knocks (not sure what it is?) when at idle and the throttle is blipped
    5. The Donford GSA also idles erratically and stalls when the throttle is slightly opened (+/- 1%)

    Video of the Donford GSA available below.

    Idle with throttle at +/- 1% open
    http://www.youtube.com/watch?v=_XXvWUcJH5w&feature=youtu.be

    Idle again, at +/- 1% throttle, after switching ignition off and on.

    Blipping the throttle
    http://www.youtube.com/watch?v=vccgCn68ZOM

    So, is this an issue with all DOHC R1200GS Adventures, in SA only? If so, why is this the case? If this is “by design” and “normal” behaviour I would like BMW to confirm this in writing and indicate there will be no long term damage as a result.

    I will continue to hound them, even if it means doing so through the NCC. I have been informed by too many other riders in SA that have/are also experiencing this and BMW fail to come up with a solution or just refuse to do anything about it. They are also told by BMW "we are not aware of any other cases like this".

    I will update this thread when I have more information.

    If you are also experiencing this please let me know.

    When syncing my '06 R1200GS, If I barely move the throttle off the stop, like the videos, I always get a big dip in the mercury stick for the left (?)cylinder. Leaving it at idle, or increasing rpm, the sync is right on. Trying to correct the dip with the throttle cable will throw off proper adjustment elsewhere. The engine will skip a ocasional beat before the engine is fully up to tempature , but never stalled and runs fine otherwise.

    Do yourself a favour. Unplug the flap control box connector. The flap will stay open due to the springs. Take it for a run. 4 of the bikes in Upington that had the same issues have had this done and all issues have been cured.

    As for the low octane map - that's absolute rubbish feedback from Motorrad SA. I saw the e-mail sent to my dealers giving this instruction. In fact I might even have saved a copy. They even have in in their advertising that there is a low octane map for touring Africa.

    Hi Bill, I did just this, removing the electrical connector plug and did a test and then also another test by removing the actual cables connected to the flap, this left the flap in the open position, it still displayed the same pinging and knocking symptoms. When I held the flap in the closed position it responded better to a blip and idled way better :dunno

    If you find it please send it to me :deal
