The shiny copper windings are the alternator stator charging coils for the battery & lights. The 2 fat double insulated coils are ignition system power coils to charge the CDI of the Gen 1 bike. The square black plastic coil is the ignition trigger coil, common to both Gen of bikes, it will be similar in Gen 3 bike.
Those 2 fat coils to power the CDI box are what allows our Gen 1 bikes to Run without a battery or a failed regulator or failed charging stator.
