It is true the clutch master cylinder level will increase as the clutch wears, just the opposite of brakes.
It's a completely different kind of clutch than earlier boxers ...

Except of course if the rear oil seal was leaking on the early boxer haha.
In the latest issue of BMW Motorcycle Magazine, Jens Staebe, Head of Technical Support and Warranty at BMW Motorrad talks about this issue as being a 'clutch separation and shift shock' issue and goes on to say that there is ONLY one approved engine oil for the GS-W. That oil is Castrol Power 1 Racing SAE 5W-40, APL SL/JASO MA2, and it's expensive (go figure). Overfilling the crankcase must be avoided. He stated that, "We are familiar with isolated confirmations of this separation behavior of the clutch, which is why we are investigating improvements. If technical measures should be necessary, we will inform our commercial network immediately." Nothing in the article mentions anything about overfilled reservoirs.
Well, Castrol oil is not available here. So, why is the 1200GS LC available? LOL! My dealer uses Motul 300 5W40, which is supposed to have the same specs as the Castrol.
At the 10,000 kms service, they did the oil change, but I specifically asked for no more than 4L. In fact, they put 3,9L according to the mechanic. They also replaced both clutch and brake lines DOT. My gear shifting, which had been improving all the time, is now almost smooth as butter. Almost. Not going into first, mind you, but I guess THAT is hopeless. I also have less clutch drag when starting cold in the morning, with 1st engaged and clutch pulled in, which caused a jump forward of the bike, and also made it difficult to move around by hand.
