Top and bottom end of the motor are in great running shape but the carb will need to be rebuilt or replaced. This was always the side quad that I let my friends ride when we went out but this has been sitting for over a year now. Tried to start it up and it would run but quickly die, had a friend look at it and he said I needed a new carb. When it did run it was an absolute monster, really torquey and immensely fun to ride. High compression!
