Haha, I don't think I could handle a 500, I'm 18 years old and my 125 gives me enough power. But heres the story.. My step dads brother gave me this bike in pieces and it was his sons bike. His son was in the middle of doing something to the motor but he was killed in a motorcycle accident. The cases on the motor are split but not taken all the way apart, I'm not sure if he was in the process of putting it back together or taking it apart? I live in Youngstown Ohio though to answer that question.
