Folks,
I'm in the process of squirting my old XS11 motorcycle. It will have a 36-1 wheel and currently has a transistorized wasted spark system with two dual output coils. While the coils work, I would like to get to a more modern coil, preferably one with a built in ignitor. I really like the GM LS2 coils and could mount four of them under the tank. Of course, if I used four of them on the bike, I would TRULY have to waste a spark by firing two coils in parallel, even though the one 360 out would be completely wasted. Given the "high output" of the 32 year old charging system, I would really like to avoid that if possible. The reason for going built in ignitors is mainly about getting the huge switched currents out of the PCM and keep it all tucked up nice an neat inside the coil for the most part.
So, does anyone have any ideas where I could get good (as good as the LS2 coils would be nice) dual output coils with built in ignitors? It's for a motorcycle, so compact is also a desirable trait... I have looked at the Ford EDIS system, but I also want to keep any external logic (aka: the module) out of the picture and let the MS do the work.
Thanks for the help!
Any good wasted spark coils packs with built in ignitors?

Re: Any good wasted spark coils packs with built in ignitors
Clint, I am in the process of doing exactly the same project, modernizing my XS1100 from the 80's with fuel injection.
My idea was to use MS to control fuel injection and ignition timing advance from a 36-1 wheel, with a Hall / VR pick up unit which would replace the old manual centrifugal / vacuum timing advance hardware on the crank, and use the ignition outputs from MS to trigger the existing transistorized ignition system of the bike.
That would enable me to do fuel injection and control the timing advance programaticaly for max power without having to change too many things on the bike. Apart from space, getting hold of parts in the bottom end of the world is not easy.
