I didn't think they'd be that cheap! What about my clutch safety switch? How can I be %100 sure it's bypassed?

With the ignition on, if the electric starter tries to start the engine when you push the starter button without pulling in the clutch lever, the lockout is missing. Ed

I'm still waiting on my ignition switch to show up but I do have a question about something. I noticed that when I would turn the key on both coils would fire together at the same time. It still does this with the hotwire. It will ignite any fuel on top of the pistons and sometimes send a fireball out of the exhaust. Is this normal?

No. Something is wired up wrong. Each coil is controlled by its own set of points and those cannot open at the same moment. Ed

I've followed the wiring to the Dyna electric ignition and it all looks good. From my understanding the magnetic pickup on the the end of the crank will brake the ground to cause spark, correct? I have 3 wires coming from the ignition. A red, white, and black. The white and black go to the coils as the ground and the red goes to the fuse box.

I'm not familiar with wiring aftermarket ignition systems, but if both coils are firing at the same time something (either the wiring or the electronic module) is definitely wrong. You may want to contact Dynatec and ask them for advice; it is possible they have seen this problem before. Ed

They only fire at the same time when I flip the bike on. When running they fire correctly.

Is it both coils or two cylinders that are firing. I don't know what exhaust you are running or if you are confirming with the plugs. If it is running good I don't think both coils would be firing at the same time.

Both coils fire at the same time when I turn the ignition to the "on" position before ever starting the engine. When this happens the gas in the cylinder ignites and shoots right out the 4-1.

If it is a 4 into one how do you know it is both coils? Mine does it but it is only 2 cylinders that fire, I think. I have never pulled the plugs to check which would be the only way to be sure, or at least 2 of the plugs.
