Well I took the Raider on a nice long trip yesterday and she overheated a couple times with me. Never completely overheated, but blew out a lot of coolant that had to be replaced.

Temperature seemed OK while running at speed until you stopped and then it shot up pretty quick. If it sat for any length of time the radiator cap would start humming and letting off a little steam. I cooled it down as best I could by pooring water on the radiator then shutting her down. I could hear the water boiling inside the head after I shut it down. I waited till it cooled off to refill the coolant.

Going to radiator shop if I have time tomorrow and diagnose it first. Hope thats the problem and nothing with the head.
