!!!!!!!!
puch cdi for the people. this CDI unit will work on puch one speed E50, two speed ZA50, derbi mopeds, and sachs 505 mopeds. more possibly too. the CDI box and coil flipping and pick up placement with be the determining factor.
just the flywheel magneto for all the experimentalists that want to use the CDI box of their
choice. we have complete sets available also.
from cuperteenland hmm.
"So we got the cdi to work on a piston port derbi, and figured out we can make the za50 box work on an e50. For the derbi the stator had to be modified, with the holes enlarged to allow more rotation to get to 1.8mm btdc. The flywheel fits most piston-port motors ok (4 of our 5), but some have extra aluminum webbing so it doesn't fit perfectly. I can take some pictures tomorrow detailing where the stator needs to be dremmeled to make it fit, and where the pickup sits for the ideal timing (had to drill and tap the other pickup location). I ended up running the counterclockwise box (za50 rotation), but it didn't initially work at high rpms, that same thing where it would only fire at theoretical idle. Flipping the coil around made it work perfect. Huge gain over points.
For the e50 to utilize the za50 box you need to drill/tap and relocate the pickup, and flip the ignition coil. Flipping the coil allows you to run the other box. With the pickup on the manufactured side, I got the timing to about .4mm btdc which runs ok, but still backfires out the exhaust. We didn't have the tap tonight, but we will tomorrow and it looks like relocating the pickup should get it in a better position (more adjustable) and right on about 1.8-2.0 mm btdc. I'll snap some photos, maybe someone can do a drawing or something then you can sell these for derbis, and you won't need a different cdi box."
Call me up or we can talk this weekend.
