1969 Honda CL175 - engine swap or not?

Hello I just obtained a clean 1969 Honda CL175. I noticed that the later models like '71 I believe have electric start. Does anybody know what it would take to add electric start or swap engines to a later model. Also if you have a good source to buy engines that would be great!

If your engine is running and complete I wouldn't bother swapping for one with an electric start. You are going ot end up wanting to ditch it later because of the ridiculous weight savings.
