Oh my did you just call him a retard,this is too much ,I have to get some sleep,lol
The CDI that banned member jaguar makes automatically retards at upper RPMs. There are two jumpers to pull to further tune the CDI if desired.
I can give you a link if you PM me.
I use it and I can tell you first hand it works to lessen vibration in the upper RPM band. My motor has never run smoother, especially for a 66cc. The Puch cylinder head has stiff compression, about 9:1 compaired to the stock 6:1 compression ratio and the CDI fires under those conditions very well. Plug is not quite right with a B8HS but I got my NGK BR9HIX Irridum sparkplug today, right from NGK![]()
Now I gotta plug the hole at a mounting stud weld on my tankRe-adjust the clutch and back to riding

Some more information about his CDI:
Repairing the KDX CDI
Maybe DaveC would be kind enough to open his up and tell us the markings on the capacitors. My cdi just burnt out and I can't wait 2 weeks so its build one or buy a stock one and I'd rather build the better one.I made my own CDI unit by copying the design of the KDX200 CDI and changing two capacitors.
The 4.7 uF was changed to 5.7uF, and the 1.5 uF was changed to a metallized polypropylene type.
Can I assume you meant 5.6uf cant find a 5.7? As for tolerance 10% that's capacitive tolerance and 5% would be ok if not better correct?
The 2nd schematic uses a pot which will allow you to vary the timing manually.
nice! it deft slows me down.I've found using the pot alters my timing as well, def' retarded- not advanced!!!
