System 71 69 499 00
=> Price

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 sure, no need to modify engine casing.

advantage over original system:
  • all parts are new
  • no wear anymore on carbons and collector
Please note!
  • Does not replace points and govenor setup only alternator.
  • Will work with any 12V ignition setup as long as ignition is based at camshaft level and a working battery
  • Can not be used if you had installed an ignition setup directly on your original alternator.
  • Does not support the original safety relay that prevents starting into an already running engine.
  • Does not support any existing electronic revolution counter.
  • Has only 180watts and offers therefore less electric power than original alternator.
