I drew up one of the designs I've been discussing with Crazy Wayne today and started testing it in LTspice. By playing around with the circuit, I should be able to adapt this to any ignition system on any bike and fit any curve. By increasing the voltage (as if the motor were spinning up) the ignition circuitry is retarding the timing like it should. Pretty exciting y'all. Vespa prototypes in the near future for testing I hope.

Electrolytic Rust Removal and Mopeds
Many times, you'll find yourself with a crusty part that you either don't want to or can't use. In this instance we-re talking about a crankshaft. I've cleaned up several cranks using this method, and it's far better than acid or abrasive - it requires no removal of material. I've used it on many tanks as well - I just finally decided I should do a writeup.
You'll need:
It is IMPERATIVE you get the polarity correct or you will rust your part and clean the worthless piece of metal. Also make sure that the two metal objects do not touch.
Plug in your power source and let er rip. Even with the worst things, I find 12 hours does about as much as is going to be done with a strong 12v power source. Please be aware that this setup will produce hydrogen and oxygen gas (it dissociates water) which is flammable. As such you should do it in a ventilated area or better yet outdoors.
The same setup can be used in gas tanks, but the anode cannot touch the tank wall (the tank is the cathode). Once again, electrical tape works well. I've wrapped the end of a piece of rebar in tape and stuck it into tanks before.
Here are some pics of the first crank I ever did... this was 5 years ago.
You'll need:
- An inert non-metallic container
- A 12v power source
- leads
- water
- baking soda
- ventilation
- sacrificial iron anode (do not use stainless or alloys - use only plain steel)
- A crusty part
