    they all make a different noise when sitting running in Neutral with the clutch engaged.
    Best bet is to go to a dealer and listen to a different one and see if yours is louder.

    Both the my 650twin and 800 make that noise, I "THINK" it is from the transmission gears spinning with no load on them when the clutch is engaged.

    As mentioned previously I could still heard the noise right after the synthetic oil change but after I went for ride yesterday the noise is now barely audible. I work on all my cars so I really pay attention to engine noise and such. From what I read the motorcycle tranny is different than that of car as the gears freely even during neutral.

    Mine is the opposite... It's fine until I let out the clutch then I get a noise like a wrench tapping on the case. This only happens when the engine is hot. When cold I do not get this noise. This started at 20,000 miles a few years back. Then in misterously went away... Now after riding from Minny-Sota to Dawson in the Yukon it has suddenly reappeared. I changed oil and it went away again for a few miles, but now back. I want to ride the Dalton next week up to Deadhorse, but am not to crazy about this clutch noise. I am at 60 ,000 miles now and other than a burnt out stator I have had no problems. Any ideas out there?

    A buddy of mine had an entire motor replaced on a "goodwill" gesture by Motorrad Mexico, last year.
    What happened was the large internal bearing behind the clutch basket inside the motor was totally shot. His drain plug had a massive "afro" of metal on it. BMW never mentioned what caused it, but he has had every single bearing on the bike go bad from the steering head to the wheels and it appears his motor bearings were bad, too. Go figure on that one.
    The noise grew increasingly louder at idle with the clutch out in neutral and was a very rough grinding sound, not at all like the video sound, this was a real growling type noise. I've never heard the sound in that video, before.
    By the way, my friend had all of his services done at the local BMW dealer and they never caught the disintegration of the bearing at any previous oil change.

    yesterday i check my clutch first i drained the engine oil surprise!!! the oil is like black water!!!! have viscosity like water i used castrol 10-40 i dont now exactly whis type is it that oil used when service my bike at dealer.
    I remove the clutch, springs disc everything is good shape, my friend is mechanic and the opinion is the bearings from input shaft make the noise and proposed heavy oil(15-50) when the oil is cold there is no bad! noise only when is hot the sound from clutch is bad but is not coming for clutch its coming from the bearings input shaft when pull the clutch lever the input shaft stop rotating or continue rotating with out load and the bad noise disappear
    I test oil 15-50 on my engine there is no bad sound now when coming hot the engine is much quieter the bike i continue the summer time whit this oil

    Costa, it's over 100f here in Mexico, today. I use 20w-50 all year round. That was the only oil the dealer sold to me when I had to buy products from them to keep the warranty here. Castrol 20w-50 branded as BMW. I have only used Castrol 20w-50 except for Mobil bike oil 20w-50 once. It is pretty much impossible to find other weights except for Harleys.
    I have over 40,000kms on the bike (F650GS 800 twin) with no oil consumption problems and not issues related to oil.
    Temps here are usually from warm to very, very hot (like in Greece but with more humidity), but I also do mountain riding in temps as low as minus 3 centigrade. I don't think you'll have any problems with the oil, I am no expert but just telling you from my experience.
    The clutch noise, if it is from one of the two bearings on the clutch side of the motor and not on the inside of the motor, will be easy to fix, however, check the big ball bearing inside the motor for play from the shaft when or if you take the clutch down and remove the clutch basket. Watch out for that one, it is the one that failed on my friend's bike but the drain plug should give you an idea, was your drain plug full of debris stuck to the magnet or was it clean and just the oil was dirty? Also, if your oil is very dirty, check your air filter hasn't collapsed into the air box. Some of the 2009 models had that problem, mine did.

    Hi i have all ready check the bearings from clutch side looks ok and oil plug is free from debris but I did not understand what situation is the bearings in the motor side if in good condition.
    You're lucky you have only 20-50 oil in the country if oil 10-40 tested in hot climates possible to have had the same problems or premature wear on the engine
    If the engine has worn bearings believe will find out soon fortunately I still have warranty on the machine:D:D
