After a long day of riding i was putting my bike on the trailer and noticed that it was leaking coolant. After inspecting it i found it was seeping out of the water tube where it connects to the front of the engine. It must have just started because the radiator was still full of fluid, so i guess i dodged a bullet on that one. Anyways, is there a gasket there, or is it a metal to metal seal? any help would be appriciated.
