That will do nothing to get to the 40 mph! with take off as fast as a normal car takes off That is needed for safe riding !
Mangum cylinders on Magnum xk or any magnum is worth about four or five HP with correct tuning but if you’re off jetting by one jet or timing or tuning of a degree or so you will have a dog!
