There is a small bleed valve beside the radiator cap, this could be slightly loose allowing fluid under heat and pressure to escape..this could be the source of the hot coolant smell..

The reason you can smell it but see no trace of a leak is because the fluid will evaporate..

This is only a guess but I suspect whatever the cause, cap, hose, bleed valve..is under the tank and therefore out of normal sight..I think sooner or later you are going to have to take the tank off for a closer look..

 I was getting the same thing near the end of the summer, while I had the tank off I noticed some anti freeze colour on the top of the cylinder head. So I cleaned it all up and then just went around and snugged up the hose clamps, hope that was the issue. I'll wait to see if it happens again. Also going to do a complete rad flush and cleaning in the warm weather.

Getting a "radiator/water" smell every once in a while, while riding.  Check all hoses, cap, overflow, radiator and can't seem to find anything wrong.  Any ideas? No water on the ground or on the engine after riding.  ???
