I am looking for electronic ignition for my RD350
Here are some of the systems I have found:
The Dyna-S is the simplest, replacing only the points:

I am not familiar with MZB, but It also looks to have a replacement charging system

The Chinoy system, looks the most complete with a new charging system. The RD350 uses an old style relay based voltage regulator, and I have troubles with the brushes now and then.

I have the German PVL system on my TZ250E but it lacks a charging coil to run the lights, which are somewhat required on a street bike.
