Cindy is right on with this.
Check the hoses especially the one upper left (facing the bike) and make sure they are snug. If you have gone through some temperature changes lately the hose can develop what is known as a "cold water leak" (different materials expand and contract differently)
What you may be smelling is a fine misting from the hose, just enough to get the whiff of coolant smell.
