Magneto for GS1000

[wera racer]

Going vintage racing with my 78 GS1000E and want to install a magneto system. I'm reading a 1979 article on Wes Cooley's bike and it says they used a Kokusan Denki CDI ignition powered by a magneto on the left side. The company still exists but I'm not finding much info on which of their magneto systems will work or if they even make one anymore for this bike. Has anyone done this mod and/or can offer some advice? Many thanks!

PM First timer ; he is building a Yoshi replica 1000 and might have a line one one.

Adding a CDI would be a major expense and significant undertaking. There are way easier and simplier ways to add an electronic ignition system to your bike, although I"m not sure if adding a modern Dyna S or 2000 system would violate vintage racing rules. If you find some CDI info please post it here so we can watch from the cheap seats.

Ed,
They do it to remove the charging system and decrease spinning weight of the rotor and improve left hand ground clearance. Well worth it for a racer.

PM sent to First Timer. The Dynatech CDI is available lots of places, just do a search. I think I got mine from Z1 Enterprises (very helpful folks). If I find a magneto system, I will post it. Thanks, all.

Dyna S and 2000 are not CDI. Do they make something else that fits a GS?

If you're looking for a self generating ignition system for a racebike - ie lose the battery, some of the ignitions available in the UK should be of interest.
Have a look at electrexworld.co.uk - there are others too. A 4 cylinder system is just a 180 deg twin with twin lead coils or like a Boyer, in series.

Plenty of GS based racebikes around the world are running with either no alernator or a cut l/h end on the crank and total loss ignition. This is adequate for most racing. Generally the more sophisticated battery powered ignitions draw more current than say a basic Dyna.

I often wish my clients had a bigger budget - I'd be fitting self generating ignitions to a lot more motors.....
