Cardan Ventilaton
I was reading in a German magazine, that on the R 1200 GS/A LC it can suck water in the cardan housing if you go through deep water. The oil and the housing is warm and it would cool of in deep water and so create a vacuum and suck water in through the pressure exchange valve.
And sure enough, at Touratech you can buy a bit of hose (for NZ$ 109.25) that would solve the problem.
My last bike was a R 1200 GS 2009. I had it in deep water and mud holes and never have I had any water in the oil of the finale drive.
I can not believe, that this would be a problem after so many generations of GS's.
What do you think?
