I've got some "so called" universal CDI kits that I picked up years ago somewhere. Looks like the trusty hose clamp method would work just fine. Basically just take the pickup and couple pieces of shrink tube to secure to it to the clamp and you're in business. Sent an email to Adrian looking for a couple 4 wire pickups that he uses on his ignition for triples. It's my understanding that he's the one that designed this ignition that Saito uses.
