Starter my Thumper (with 6 miles on it). After about 5 mins, I turned it off and the was a whining sound which was from the resevior under the left fender. It also spit a small amount of fluid from the PINK drain hoses. The fluid was up to an inch from the top of the resevior. I do realize that it will rise to the "hot line " when hot, but seemed a little excessive.
