We are going to compare the performance of the Russian design, from the 'Roll your own CDI' thread to the Chinese design, from the 'Reverse engineer the Chinese CDI ' thread.

Also we have built the Jag modified CDI, and will do some testing on that as well.

I plan on making the simple version from 'roll your own', with a retard.
But I am waiting for the mailman right now, we've all been there :)

I then plan on making the Jag clone.

Looking forward to how this thread develops!

Why don't you include the stock kit CDI too.

How are you going to test them so you get accurate info?

The 9.5 HP Arrow Motorized Cycles case reeded race motors use the stock CDI.
The stock CDI is the Chinese reverse-engineered version.

We will test for pulse width, amplitude, advance/retard curves, etc.
