Well my leak came back :-| I’l talk to them about changing the breather.
 
Transmission breather replaced. I hope this fixes the leak.
You had that done? ... that mechanic is going to love you (insert sarcastic grin here) an inexpensive part ... in a really hard to get to location :LOL: I hope that fixes your problem.

Yeah, they determined the leak was coming from the breather…. I hope they put everything back together correctly.

You go ahead and "hope"... Me, I'm basically taking everything apart and then fixing what the mechanics stripped, cracked, scratched and lost...

I was pissed after they replaced my headlight.. I was missing three $8 screws and two clips...

My thinking exactly DIY and know it is done right and with care. Mechanics don't have a 'Dog in that fight' and just do a job ... some very well .. some not so much .. just y 2¢ ;)

I’ve had nothing but great service from this dealer so I’m not worried.
 
I just read through the service report, here are the highlights.

  1. Removed L/R Battery covers, throttle body covers and airbox covers and confirmed leak coming from breather.
  2. Removed L/R throttle bodys, air filter, seperated air box from bracket and engine.
  3. Inspected breather valve, covered in oil, small hole present in exterior rubber. BMW approved replacement and running of bike w/o covers to confirm fix. Performed extended test ride to confirm leak no longer present.

4. Replaced all hardware that was easily accessible and within reach at the time of work performed.
 
So far the oil leak has not returned. My assumption is that the breather was pinched, punctured, cut, split or whatever during assembly. I just don’t see how it could be otherwise.
 
Mine has not returned either, so it might have been the breather after all ... sigh ... but I am glad you are good now as well ;)
 
Well F..k F..k F..k !!!!! That little Breather thing is real easy it just has a barb and plugs in there .. the trouble is it is under the ducting system for the air intake!!!! I now have the whole top of the bike removed and can see it well . It is very wet around it, so I am pretty sure this is the culprit ... but now I have to figure out how to lift the air intake up to get to it ... and it seems to be one huge piece with the rubber connectors to the cylinders permanently crimped on it .. anybody has any ideas? I was thinking taking out the 4 screws that hold it and the 3 screws on each cylinder so I can hopefully lift it up enough to change that thing ... anybody done that? Any suggestions are welcome.
My 2024 Roctane transmission breather leaked oil after changing to 75w90 for first 600 mi service...Only after changing oil back to stock 70w80 oil did it stop leaking...
