the elec start motors use a different frame from the kickstart models. if putting a k/s model in place of an elec start, it may fit. but putting an elec start in place of a k/s...forget it. the frame is bowed out in front to clear the starter motor, but not on the k/s model. if they are both the same, you should be able to swap. just make sure you can live with the difference in trans gearing.
