Honda CBX550 ignition coil problems?

I have the above motorcyle and one of the ignition coils burnt out. I replaced it with a new one from Honda and it went well for a couple of months. I had it parked on the drive for a number of months while I carried out other repairs. Fired it up and only running on two cylinders (it has four cylinders) again. Traced the HT leads back and the new ignition coil is faulty. I have checked the pulser pick-up coils with a multimeter and the reading is within the spec's given by the Haynes manual (which couls also be wrong!!). Any advice would be gratefully recieved by a frustrated home mechanicHonda CBX550 ignition coil problems?
Just because the resistance values show ok, don't always assume the pickups are good. I've had then show ok but were bad anyway. Here's what you can do to determine where the fault is. Swap ignition coil wires and with the plugs out and on top of the engine, see if the same coil fails to spark. If so, then you know that's the problem. If not, suspect the pickup. With the ignition on, you should be able to tap the little metal center of the pick up with a screwdriver or other metal object and cause the plugs on the appropriate coil to spark. If not, suspect the pickup.Honda CBX550 ignition coil problems?
