Thanks, I actually just found a really good comment somewhere on here from Marc Friedman that explains how exactly to do that as well as some other quirks of Kinetic style CDIs on stock vespa points cases. Another reason I want the CDI is to run DC straight off of my stator, this CDI will do that right? From the lighting coil? I need to reliably run a DC Bosch water pump for a water cooled set up and I think a CDI will help me do that but I might be totally off.. If its AC can I convert it to DC before my rectifier? Sorry I'm getting off topic lol. Here is the comment tho, from this post:
