Recently purchased a 2014 R1200 GS. Cold here in North Georgia, so decided to do some maintenance. 14,500 mi. on the bike. Decided to do all the fluids since unsure of status. Brake fluid flush was enlightening. Front and rear master cylinders contained white goo. First time I have ever seen this in any brake system. Sent the pictures to my buddy and he pulled the cover off the front master cylinder of his 16 K16. Same thing except much worse. Both bikes obviously have original brake fuid. What the hell kind of fluid do they put in these bikes from the factory? Never seen this in any Japanese or American bike or car in my 64 years.
Top image is my GS, bottom image is my buddy's K16. The same goo was in my rear master cylinder as well. Got all the goo out, flushed all old fluid, activated ABS with GS911, and rebled system. All good now. Pretty nasty stuff. The K16 only has 7,000 mi.
