Hi There, i have a 1983 XR 350 and the CDI has failed. I am modifying it to take the new XR 50 - 600 1995 one with the 4 and 2 pin set up and not the round 2 rows of 3 have checked the Wiring Diagram ... and all the same cables go to the correct same components. So changing the Pin out and also replacing my faulty Pulse Generator that I have coming from germany. Will keep you posted as to how I go. Thanks Westy!
