Just rebuilt my KTM 2 stroke, and when i put the coolant in i decided to use just distilled water so i could flush out the system before putting in regular coolant. Well after starting it up for the first time i decided to go on a short ride around the neighborhood and thought there wouldnt be a problem. When i came back from riding about 2 miles, i noticed water on my bike and thought it was a leak. I should have known before i rode it, but the radiator did overflow a little. I did not let the bike stand still running at all. Is this normal for it to overflow that fast and could it have done anything to the new engine at all?
