I replaced these components with new ones supplied my Euro MotoElectrics at no cost to me in support of my goal to auction this bike and donate all the proceeds to the Motorcycle Relief Project. EME has been very kind and generous to me on this project.
I installed their new Type 1 charging system kit, the EDL-1 107, which has all the parts to replace the stock 240 watt charging system including a new front crankshaft seal.
I also installed their remanufactured electronic ignition sensor, aka, the “Bean Can”, and a new ignition system sub-harness.
You can read about how I did the work and see a YouTube video.

This is what I started with.
And this is the final result.
