ignition control units

[ironmonger]

I finally drug out the GS1100E after having it parked for a number of years due to circumstances beyond my control... When I parked it I had a few problems that have since been corrected. The valve seats were recut with Neway seat cutters, work great by the way, and the valves were refaced on my lathe. The valves were then lapped and tested and are now holding tight.
Upon trying to start the engine, I found a very weak spark and the 1-4 coil was running hot and no spark present on the 2-3 coils. The coils are new Accel coils and both read 4.5 ohms. I have come to believe that the ignition control module is bad... they are also over $400 bucks from Suzuki...
Has anyone designed a replacement ignition control? I am going to pick up a 1974ish ford ignition control module and give that a try to run one coil and see what happens. That era of fords used a reluctor and transistorized coil... no CDI, and may work. The other coil may get the same control with the reluctor leads inverted. Even if I have to buy them new they are less than $30 bucks apiece. I have seen the dyna products, and while they look great, right now I would like to cheap out to get thing running.
Let me know what you have done.

dyna S is the standard replacement for the ignitor or you can find a cheap OEM replacement

suzuki made 2 igniters that do the same job.
one is a black box.
the other looks like a module.
same wiring and plugs on both.
they both bolt on the same.
i have both types that test good.

blowerbike,

Sorry to hijack this thread but I've got the same issue going on here with an '81 GS750. I've tested everything on the ignition, and gotten a 'new' ignition box from the salvage yard. They said if it's no good I can just bring it back... Could I potentially get one from you?
