Specs At A Glance

Good To Know

Q: Does this CDI box plug into the stock wiring? A: It uses the factory-style connector so it installs in place of the original module on the listed STX 750 application. Confirm your part number before ordering.

Q: Can a bad CDI box cause a no-spark condition? A: Yes, a failed module often stops sending spark signal, which prevents the engine from firing. Replacing it with a matching unit restores normal ignition.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
