Wow! Stumbled on this thread today. Just got my 2012 F650GS Twin less than a week ago. Rode it home....84 miles and as I was inspecting it, I saw a little white stream on side of the engine. Looked at it and could see it came out of a little hole.
I wiped it off, thinking that it must be some kind of overflow, but didn't know why it was white.
Very hot here. Upper 90's all week. I have less than 200 miles on bike today and saw a tiny bit that had leaked out when I got home.
I'm making a note of this and when I go in for my 600 mile check, I'll report it.
I was just hoping it would be nothing. But.....already a water pump replacement??!! Hard to believe!!
