pic couldnt catch the bubbles as it was on idle...but was def leaking out, and i dont know how i just now noticed.....also noticed the lower hose (about 1'' worth would appear to be wet..etc) what i think has been coolant...im not quite sure what all this means, but from what i gather on here, it seems to need to have the waterpump rebuilt, or seals replaced etc...
mine does the same thing no need to worry, there is a "tell-tail" on the water pump shaft that will leak if the seal needs replacing, and it will drip out and onto that black oil line, thats ok, not a head gasket problem. However if you replace the seal and it still leaks from there good chance the pump shaft is scored and may need replaced or a quick buff with emery cloth. ( i have had faulty seals too that will cause it to still leak)
Mine problem is that the shaft is scored and I tried to buff it up with emery cloth no success, i left it and just top up my bottle every time i ride, but this year when i get the money ill replace the whole pump. hope this helps!
