okay, so a month ago I bought a puch cdi high rpm box off treatland, to rebuild my aging Star Fire. Just today I had a revelation on how to get it to work, and in retrospect, it's bloody simple and I shoulda realized it sooner.
The wires coming off that box are Black: Kill, Black/white Ground, Red: Hot off magneto, and white, which is the hall sensor wire.
HT motors have a black, blue, and white. The puch CDI wires up straight to a HT magneto, Black to Black/white, Blue to red, and White to white.
Yep, that's right. The white wire does serve a purpose. The Puch CDI is a much nicer unit, though the timing in the low end seems like it might be somewhat retarded. An adjustable timing magnet would be ideal for this mod.
