Dyna S Electronic Ignition on KZ900

I have been considering putting a Dyna S electronic ignition in my 1976 KZ900 and just wondering if anyone wants to share their opinions on these over the stock points system.

Are these really maintainance free like they say? Is installation easy? Should I replace coils at the same time? Any performance advantages or disadvantages?

lower maintenance,more reliable in my experiance.you dont need to change coils if they are still good

I would put it on, better spark, less trouble, and you dont have to change the coils if yours are good, but I would recomend replacing them.
Also do the coil wire mod while you are there
