Hello and thanks for reading my post. I just purchased a 1978 Magnum MK2. The bike was adult owned and in BEAUTIFUL condition. It has 3000 miles on it and its all totally complete and all stock. The bike will do about 28 MPH tops. I need this bike to go around 40 MPH. Is there anybody out there I can send the motor to who can build it for me to give me some BALLS? Not looking for 60 MPH just enough speed to keep up with traffic on a 35 MPH roadway. Whos the best motor head out there? Thanks Ricky
