Yeah Ryan i dunno whats up with that
i cut apart my 2041 box when it fried and the main power cap was 150v mylar film- just about the shittiest cap you can possibly get. I would guess just based on # of turns and wire gauge that the Treats CDI is capable of 200-300v, especially at high rpm.
given the bad quality of the capacitor, it could be that you just happened to get a magically good one, or a magic weak CDI stator? I dunno, shits crazy. We're talking about mixing and matching some radically different stuff here so its pretty cool that any of it works period.
My guess is the pietcard stator coils (just based on the size alone) only put out the 100-150v that the CDI box is designed for.
