My 2022 R18 B requires 1.15 L for the Transmission; basically, 2 x 500 mL bottles + a measured 150 mL = 1.15 L.@Scott Semone ... soooo I measured what came out of the transmission and it measured 1.2l hmmm maybe I did slightly over fill it ... considering Uschi puked some out .. there must have been at least 1.25' in there .. and I know how sensitive these things are to over filling ... and then I also noticed that the oil was foaming a bit when I poured it into the measuring jug .. that will do it every time!!! ... so I will try refilling it with Bel Ray Hypoid oil .. not that Scheaffer one anymore and make damn sure it is 1.1l and see whats happening ... if she still leaks I just have to pull her apart again ... I am getting used to it ... sigh
Is it a faulty breather or an overfilled transmission case, and a functional breather valve..?It is definitely coming from that little breather, I managed to lift the intake assembly high enough up to get to it and remove the old one.

soaking wet and only the area where it is is wet ... well Monday or Tuesday the new one will be here and I hope I can get it seated without having to take any more bike apart.
It could be that it was slightly overfilled ... but not by much ... and it didn't start gushing until 3500 miles after the oil change ... very odd ... not sure if that breather is the problem either ... but it was very wet around it .. I already ordered a new one (that black rubber doohickey in the previous post) and I may as well put in the new one after it arrives ... the part number from the original has changed, so there is a chance that the new one is re-designed ... the old one is the same part number hat the R1200C has ... maybe BMW tried to re-use existing parts and then changed their mind about it .. not sure. There is no separate valve this one is a goofy one-piece rubber thing.Is it a faulty breather or an overfilled transmission case, and a functional breather valve..?
Maybe the fluid is breaking down and or bubbling, causing it to expand?It could be that it was slightly overfilled ... but not by much ... and it didn't start gushing until 3500 miles after the oil change ... very odd ... not sure if that breather is the problem either ... but it was very wet around it ..

My thoughts exactly!!! she stood for a couple of weeks when it was nasty out and/or the oil drew moisture and that did it ... in any case I am switching breather AND oil brand. We will see soonMaybe the fluid is breaking down and or bubbling, causing it to expand?
Maybe a faulty breather allowed water vapor to enter the system, condensation, etc. etc starts snowballing into a foaming hot mess...My thoughts exactly!!! she stood for a couple of weeks when it was nasty out and/or the oil drew moisture and that did it ... in any case I am switching breather AND oil brand.

Could be .. in any case I will see soon if that is what it was ... or if things go sideways ... start over again with the trouble shooting ... sigh. Now the wait happens, until FedEx arrives.Maybe a faulty breather allowed water vapor to enter the system, condensation, etc. etc starts snowballing into a foaming hot mess...
One so far. I put a paper towell under the bike when parked, if it leaks again I’ll spot it.So it only happened once? ... hmmm I changed to oil about 3500 miles back and it just started doing it .. so I don't think over filling is the issue here ... I did order the newer style breather from MAX, it should be here early next week. In the meantime I will tear off the top covers and see what I can find there.
YupOne so far. I put a paper towell under the bike when parked, if it leaks again I’ll spot it.
I haven’t had any drops on the floor since I took it in. But I’ll never get all the oil and dirt that it picked up out of the bottom of the bike.So ... just following up on this, no more seepage changing the breather and changing oil seems to have fixed it ... I am still not convinced that it actually was the breather . I suspect the oil 'foamed' and made its way up to that breather where it seeped out.
Well ... let's hope we have that one whipped !I haven’t had any drops on the floor since I took it in. But I’ll never get all the oil and dirt that it picked up out of the bottom of the bike.
Had the same problem. Oil dripped down from the breather and was baked on the right muffler.@fleabag Did you ever get that figured out? .. Uschi started doing that too .. real bad. Got to work this morning and noticed a burned oil smell ... looked down and it was all over the right side pipe, tire and saddle bag.

Definitely coming from the top of the transmission, but there is really no opening there other than the 'Breather'
So I looked it up and saw that one part number has been superseded by another part number ... wondering if that is the problem???

Wow .. that looked identical to mine ... no dealership around here anymore .. so I just did it myself ...Had the same problem. Oil dripped down from the breather and was baked on the right muffler.
I annoyed the dealership until they agreed to replace the breather and the right fishtail muffler.
Fixed the problem. Here are some pictures of how mine was.
Also, when you sort this out and go to clean the bike, Make sure to use some compressed air or the exhaust side of the vacuum with the high pressure tip and really clean the bottom of the bike. Especially the electronic module down there as oil pools in there. Happened in mine and I ended up loosening its bolts to really get in there and wipe all the oil off.
