Default Roll Your Own CDI

Found schematics on the Russian motorized bicycle forum:

for the CDI, so I'm going to start experimenting, looks very simple and can be tailored for use with any old ignition coil you have lying around.

The 2nd schematic uses a pot which will allow you to vary the timing manually.

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 tank Re-adjust the clutch and back to riding

..getting into confrontations with the mods. To the point of them pulling his posts.

I disagree with many things that go on in forums but I like to help people so I usually bite my tounge. I have fired what I call broadsides at people when I think there's an injustice. Gotten threads locked but never banned until I was on the other motorized bicycle forum and got banned for not doing a search for someone else :/

I can find him if I have to and I do, I want another ignition box for the racer I'm building
