12 volts generator for Yamaha XS650 output at 12V/180W DC - alternator only!

For complete ignition see system 71 69 999 00.

Replaces old alternator and regulator. Though the alternator is technically capable of running without a battery (which the stock alternator could not), your ignition will need the battery to get started. The electric output generated during kickstart is not enough to start ignition reliably. You imperatively need a battery.

No carbon / collector problems any more and no need to modify engine casing.
