....overflow hose is clear (I have to top off the overflow tank occasionally). Yesterday during warm up it spit coolant out the 1st connection at the base of the radiator prior to the thermostat. I have had leaks aft of the thermostat but not much. The Samco hoses (KTM orange of course) do seal better. Before installation, coolant pushed out from most connections, especially from those lame 1 time use factory clamped connections. My theory (I am a mechanic but work on HD/Buell V-twins) is the thermostat is not popping off at the right temp and overpressurizing the system. The reason for the post is due to the sheer agony of pulling apart and changing out the thermostat (many an F bomb will be dropped), is there anything else I should check?
