2003 660r, having cooling problems. The last big ride of 2010 my bike started running hot while at a idle, as long as I was riding it would not do it, this has never happened before. About 2 months before this I replaced all the internals of the water pump except the impeller because it was starting to leak from the weep hole. Last week I flushed the coolant system and replaced the thermostat, which the old one was not stuck I found once I got it out. With the new one the over heat light did not come on but the fluid level in the Radiator never changed either from the initial fill up from the thermostat chenge. Hoses feel like they have enormous amount of pressure on them like the thermostat is not opening. Could there be blockage some where else.
