At Mike 52's advice I just fitted a Chinese pit bike CDI and coil to my 1984 Husky 500AE retaining the SEM stator and it has turned it into a 1 kick start bike! Couldn't be happier. The old SEM CDI coil unit would require me to try to start the bike at least one full race earlier than the race immediately before my gate on club VMX days. I run a decompressor on the big girl so I can start it like a girl!
Here is some shots of the installation. The coil, CDI and kill switch (I didn't use their kill switch and used my Magura) cost $27 buy it now on eBay. The eBay seller is chinkychonkbikes (no I didn't make that up!). I had to replace the connector plugs with larger ones that fit the SEM. The wires are quite thin. It's what you expect for $27 and with the use the bike will get should last my lifetime!
Note the CDI blue/white wire = trigger = green from SEM stator
Black/red = power supply = red from SEM stator
Green = earth = black from SEM stator
Hope this gives people an alternative to more costly options before deciding that the stator is cactus. Old SEM and most likely old Motoplats with weak spark can be reinvigorated with a modern CDI and coil for small change.
