Hello guys! I tried asking this question on some motorcycle forums but I think you guys will be of more help. I am trying to build an electronic ignition for my 1979 Kawasaki KZ400. I browsed around and found little parts here and there but I'm wondering if anyone knows of any tutorials or guides to follow while doing this. Any help would be greatly appreciated. Thanks in advance!
google mega squirt and micro squirt. They are injection / ignition diy stuff, maybe that will help you get started.
I can tell you that you will need crank position and cam position to time your ignition events.
