PowerDynamo electronic ignition and generator for BMW models. Use to convert from 6v to 12v (you will need to replace your bulbs). This is a new generator/regulator and magneto ignition with an integrated solid state ignition and magnet-based generator which upgrades your bike's ignition and electrics. See all the pictures to verify that this is the correct system for you. Comes with all the items shown in the picture plus a correct flywheel puller.
Magneto with integrated solid state ignition, output at 12V/150W DC. Ignition with own power supply from within the system. Replaces old generator L45/60L, regulator, magnet unit, centrifugal advance unit in above listed BMW with either 17mm or 20mm crankpin measured at wide end. Choose option from drop down before adding to cart.
Does not require changes to crankcase. The system is technically capable of running without battery. All the 12v components are out of sight behind the front engine cover or tucked under the tank. No extra wires run to the headlight--the bike looks completely stock. The difference you will notice is how much easier the bike starts and runs, and a much improved lighting system..
System has ignition triggered on crankshaft which not only eliminates wear between crank and cam influencing ignition, but also frees the camshaft place to install de the ignition coil there (as this system does)
Also timing is easier as you have at crank level full angles.
Advantage over original system:
BMW R50, R51/3, R51S, R60, R67, R67/2, R67/3, R69 with 17mm crankpin (measured at wide end)
