Just a common CG...If you look at the pic he has, you will see his existing throttle cable.
The one I linked to is the usual normal size cable for the average China Girl motor series.
It probably failed and broke the way it did because it was routed incorrectly right underneath the motor getting heated to death and then seizing up real tight inside the cable housing until you turned the throttle as it was probably pretty stiff and then it snapped off the barrel end.
