Got in touch with Jiri at Ignitech and the Sparker TCI is only $129 USD plus $36 shipping. Really a good price, the ignition box handles both coils. I may not need it though. I've been carrying a screw driver and riding and adjusting the pilot screws. Adjusting out the rough spots. The bike is now running much better. I can actually ride it without having to wrestle it. I can go through the gears in town at low RPM and I'm in the sweet spot when I turn the power on. Of course we'll see what kind of a mood the "old girl" is in tomorrow...
