After you clean and dry off your bike, set it over a dry spot in your garage overnight and see if it's leaking anywhere. Mine starting doing this last year, turned out to be a cracked overflow bottle.
It drips oil over a period of time but no coolant but i can swap out my 07 for this one. But a cracked overflow will cause that? It comes out of the hoses at the top.
Oh so it's leaking out of the overflow tube at the top of the radiator?
Could be a bad head gasket........
HIS COOLANT LEAK IS COMING OUT OF THE OVER FLOW TUBE OUT OF THE RESIVOIR.
is the bottle leaking?
