    The dead give away is the sound varies with the clutch disengaged/engaged. As I said: bad bearings. Contact Anton Largiader. He knows BMW transmissions like nobody else.

    Could also be a cracked flywheel if the noise isn't happening in neutral

    I don't know what's causing the noise..
    could be the gearbox
    listening to the clip, sounds more like an engine or clutch noise to me.. that's all I was saying..
    Not sure about the smarminess , you mad about something?

    Anyway...
    OP
    How many miles on your GS?
    If you haven't found this thread, take a look..maybe it will help you
    There are even threads within the thread..
    folks have plenty more thoughts and experiences to read through...

    Usually this sound is produced by the splines between the clutch plate and the transmission input shaft. They are dry and in your case loosely fitting or worn.

    thanks for the replys. I have my eye on this . Very close to me. What do you think. http://www.adverts.ie/6188268
    my bike has 33k miles and is a daily comuter. Would this 08 gear box fit a 04 bike.
    My bike might go for another 100k with this noise. I think.

    Quotes from the used trans ad, seller wouldn't know as he allegedly never installed it:

    If it is both the exact same noise and it's very common, perhaps nothing is actually "wrong" with it.

    Yup, though sounds a bit pronounced. The motor is not running smoothly at operating temperature. My 1150 does this until it's warmed.

    All these things plus new sparks correctly gapped and a correctly performed TB synch will help the motor run more smoothly when at operating temperature. The noise will likely quiet.

    Don't freak out about some catastrophic event looming until you've taken care of the simple stuff first. The OP said he changed the trans oil but didn't report on what the old oil looked like. My guess is it had no appreciable amount of metal in it.

    Some of us actually WORK on these bikes. The post below accurately describes what has been my experience:

    I did inspect the oil. The last owner seemed to be good at keeping records of all service work which he did himself. Receipts to prove his oil purchases.

    The last gear oil change was 4K miles ago . The oil that came out yesterday was still very fresh looking and clear. Going slightly dark with no bits of metal.

    This noise only happens on idle with clutch lever out. If I throttle up to 2k revs, it disappears. Also there is no sign of it while on the move. I have not tried to balance throttle bodies yet as I dont have the gauges or know how yet. But its on the list of things to do.

    Thanks so much for the reply's so far. They are a real help

    No metal in the oil indicates the trans is fine. Most reasonable people will agree with this. The sky is not falling, no looming catastrophic failure, no need to get hysterical.

    New plugs, adjust the valves and synch the TBs, in that order. I use a twinmax, and there is a good, if somewhat long-winded procedure in the Hall Of Wisdom. If you do these things yourself you'll get a lot of valuable knowledge about your bike, satisfaction and peace of mind.

    Cheers! :thumb

    My 08 sounds the same. At 60,000 the sound hasn't changed. Quiet with lever in. Other than a little embarrassment at a stop light, no problem.

    All bikes I've owned have a distinct rattle in neutral with clutch out. GS is no exception.... This is normal!

    I'm not so sure that is normal. My R1150R never had a noise like that with 32000 miles on it.

    Normal noise. My mechanic tells me (if I explain correctly) that a rod from the clutch slave is rattling. It has a felt washer or felt covered and that wears away and then it starts making that noise. I've heard from others that have fixed it that it is a several hour job, but not a major teardown to get to it. So ride it until it bugs you so much you need to fix it. Or if it is something else, it will get worse and you'll know what the other problem is. BTW, mine has made this noise for almost 30k miles. Only in neutral, with clutch lever released. A blip of the clutch lever sometimes makes it go away briefly.

    In fact, if this paste works, here is a parts diagram that shows the felt ring. Item #9
