Disconnect all electrical plugs and connectors associated with the CDI ignition system, stator, lighting, and accessory circuits.
Securely mount the new stator assembly to the engine crankcase cover according to manufacturer torque specifications.
Route the new wiring harness following established chassis pathways, ensuring clearance from hot engine parts and moving mechanical components.
Connect the stator output wires (AC power output) to the corresponding input terminals on the new regulator/rectifier assembly.
Connect the CDI unit, ignition coil, ignition switch, and starter relay plugs to their respective mating connections on the main harness.
Ensure all ground connections are securely fastened to the vehicle frame or designated ground points.

- Stator replacement requires removal of the flywheel, which necessitates specialized flywheel removal tools.
- Proper wiring diagram cross-referencing is mandatory for accurate system function verification post-installation.
