Good To Know
Q: What causes a CDI box to fail? A: Heat, moisture, and voltage spikes are common causes, and symptoms include no spark or cutting out under load. Replacing the CDI is often the quickest fix once wiring is ruled out.
Q: Does pin count alone confirm compatibility? A: No, the connector shape and wiring order also matter. Match your stock CDI against this 5 pin unit before ordering.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
