    Your pic shows correct way to test primary coil resistance,assuming you put meter on lowest "OHM" setting (probably 200 ohm). Seems weird that you have a bunch of coils with high resistance. Go to Radio Shack and buy a 100 ohm resistor and test your meter.
    I tested them with another multimeter and the ignition coils were both around 6 ohms. That seems close enough to be able to rule them out. What else can it be? Should I just take it to a shop? How do I test the igniter, I don't really get the procedure on Bikecliff's site?

      That sounds better, but I don't know if 6 ohm is too high as compared to 4, but maybe it's a meter problem.
      Remove signal generator cover ,remove #4 spark plug and hold against engine with plug wire attached. With ignition and kill switch on, slide a small screwdriver tip pass the signal coil for #1 and #4 (it's marked), plug #4 should spark, signalling that ignitor has picked up signal and done its thing. Does this make any sense?

        I actually figured it out. I used a five pin relay for the coil mod and one of the pins that go to the coils stopped working. I tinned two wires to go to the working pin and voila spark on all four cylinders. Thanks for the help!

        Now I have a better problem, I have a cracked valve cover, probably courtesy of the cheapo torque wrench i used. The bike started right up but starting spilling oil everywhere. The motorcycle gods have been looking unfavorably upon me.
