I fired my bike up yesterday after about a month of off and on work. I had previously flushed the cooling system with deionized water and refilled with Yamacool. All hoses were replaced including the hose to overflow tank and a new rad cap just because. This was not part of the work I had been doing. Anyways, I noticed a brief coolant leak that seemed to happen as the bike was getting hot and it wasn't from the weep hole. It did it again today. It's coming from the rad cap which is tight. I'm not getting an overheat light and the cooling fan does cycle off and on. My cooling system service did not include a new thermostat, but the bike wasn't doing this before. It would appear that it has started after having sat for all this time. Is it possible that I have now somehow ended up with a malfunctioning thermostat?
