I noticed this today. Where is it coming from? Anybody else have this issue. I read posts that said something about O ring behind the water pump.

 

If the water pump seal goes, coolant leaks from a weep hole at the front of the crankcase. In later models, a hose was attached to the weep hole. The hose goes to the left side of the bike. Usually the first clue that there's a coolant leak from the water pump is a little puddle of coolant beneath the bike. I can't tell by the photo what the substance is. I'd be inclined to wipe it off and see if it happens again.

 

You sure you didn't pick up a little drip off the road?
