Alright heres the story ... my banshee heats up to over 220 degrees (temp guage doesnt go any higher ), and then I shut it down and let it rest. Then get back on it when its at about 100 degrees... then in about a minute its back at 220+ so i let it cool down again, and again, and so on... It just started doing this last week so I thought it was really lean, but Its not the jets because I changed them many times with no difference. I, and other people may think its the water impeller. so far, I took the water pump cover and the cover thats inside that off and some anti freeze leaked out. Are you suposed to be able to turn the impeller 360 degrees by hand? I heard that from somebody but they werent sure if it was or not. Any other information on what it could be would be great. ( by the way - I didnt change ANY hoses / coolant level / etc at all! It was running fine until I ran it in the cold weather ( 30 degrees F, then it started doing this)
