For Those Who Had Bad Igniters

I'm wondering if I have a bad igniter. If you've had a bad one, what were the symptoms? Did you lose spark entirely, only at certain RPMs, or was it weak instead?

I've been through the carbs on a bike 3 times and acid washed the tank, new fuel filters, etc. and it still drops one cylinder below 2000-2500 RPM. The igniter seems to spark all plugs at all RPMs and the coils test good. Both cylinders have acceptable compression, 150+ on the one that isn't firing, 160+ on the one that is, dead cold (like 40 degrees) after sitting for a couple of days. The igniter fails every single test on the chart in the 1995 manual though on a 2005 bike. It doesn't seem likely but I'm not familiar with the transistorized ignition circuitry inside the black box.
