Research the CDI pinout, disconnect the key-switch pin, verify spark, and kick start (or use a socket in a drill on the cooling fan). If the engine starts . . stop by disconnecting the trigger coil bullet connector from the stator. Then reference a wiring diagram and troubleshoot the starting motor circuit with a multi-meter continuity function.
