Ignition Coils

I have been having some mid to high rpm range issues with my 85 gl1200I. I suspect bad coils, but not sure. I have tested the fuel pump output and it is way over what is called out for a minimum. The carbs are freshly rebuilt to the degree that i even put new felts in the throttle plate rods. They had a bath in the ultrasonic cleaner, followed by a using a water pic personnel water jet cleaner to verify all the ports where in fact flowing. Yup lots of overkill here. All vacuum lines have properly seated new o'rings as well as rebuilt air cutoff system. When i checked the coil that is for cylinder 1/2 it was below normal on the primary side, 2.4 ohms. When i checked the secondary side using my fluke 87 DVM set on M ohms, i got NO reading, as in OL. Checked the other coil and same thing. I had the coil still mounted in the bike at first, then tried it with it detached from the frame, but still in the bracket. I know the coils have to have some resistance or the bike would not run at all. So dear friends and fellow bike wrenches, what an i missing? Air/fuel/spark. I have both air and fuel with limited spark it seems. Thanks in advance for any input.

if the coils need replaced, go to a junk yard and pull the coils off of a Dodge Neon car.

the mounting plate is a near fit for Goldwings.
