For those who have asked:
my Transistorized Ignition (aka Hondaman Ignition) operates from 3.8 volts to 24 volts without change, but will operate the 6-volt bikes better (when cold) with a slight mod I do if I know it will be for a 6 volt engine. It reduces high-RPM spark droop through controlled coil field breakdown rate (yes, Patent Pending, research ensuing to ensure non-conflict with Ford) through 16,000 crank RPM. It also removes the cold-blooded tendencies of the more inexpensive, temperature-sensitive tungsten points we are all suffering today (unless you are fortunate enough to have the superior TEC points) by always providing the full coil switching current, from startup.
Honda's coils produce more voltage when warmed up to about 80 degrees F or more. They droop significantly below 50 degrees F (about 6500 volts output on cold start), and don't droop up high until over 180 degrees, and then not very much (about 7200 volts, compared to normal 7500 volt output). Their magnetic design is better on the coils made after 1995, when they became the ones you can buy today, with higher dielectric rated insulation on the bobbin wires and better lamination uniformity on the metal plates that make up their cores. My unit senses this difference in the coils and alters their discharge rate accordingly, which provides the more uniform spark voltage over the whole range. While it has a limited range over which this works, this range falls directly in line with the types of coils used by Honda, Suzuki, Kawasaki, and Yamaha on their points-fired bikes from 1964 through 1980. most of which were designed by Denso Hokai.
Thanks for prodding me...
