AC-CDI Honda XR400

ADAPTATION to fit a Honda XR250 / XR400R Done by   Characteristics Based on AC-CDI PIC16f84 v5.4 For single. 1 advance curve. No kickback.   Introduction Andrew has build a AC-CDI for his 2002 XR400R. Mains changes are: – He use a 2.2uf 380v capacitor, and the same configuration of the rectifier diodes he saw into the original cdi. – No battery is used and the cdi is directly .
