Do you have a picture of the CDI unit ? (some 650’s have 1 or 2 black boxes) (If it has 2 black boxes , one is for the general bike and the other one is more for ignition control)
Also, trace the wires from the rear coil => match their wire colours to the black box it ends up
Download the service manual (I uploaded many in this forum) so find one that matches your bike, and use a pocket meter to test the CDI unit
