I have rewired my bike without realizing that the stator in the diagram is on the points ignition while my bike has CDI ignition.
The first picture here is the diagram I found.
The second one is my assumption on how it would be rewired with respect to the CDI ignition. Can anyone tell me if this second diagram (I drew it) is correct? I am a little confused if the white wire coming out of the stator is in the correct place....? Any suggestions would be greatly appreciated!!

Ignition looks right, white, red & green from the stator to the CDI with the second green on the CDI going to the headset to turn off the motor by grounding it.
I'll just assume the rest is proper.

That looks good. When I rewired one of my stators for electronic ignition, I didn't wire in the second green (kill switch) to the stator. Instead I just routed it from the junction box directly into the CDI.

Your diagram does not look correct to me.

White Red and Green from the stator go directly into the first 3 slots on the left of the CDI. The last, most right, slot on the CDI takes the long green kill switch wire from the wiring harness.

Your diagram looks like it has the two green wires backwards.

It doesn't matter which way round the greens go as they're connected together.

You're right about the CDI green wire. I changed it:

Can I get a high-definition version of the diagram?
