It would be odd for two carbs to do this, especially two cylinders that fire off the same coil.

This is advice from another thread, give it a try.

Skip the ignitor part. You can at least test the coils and if you find out the spec for the Dyna then you can check that out as well. You should be able to find out from Dyna or someone here what readings to look for.

Is it possible for my dyna s that i just bought is bad all ready

Make sure all the wires are hooked up under there. Maybe they are falling off. I had a coil wire come off at the track and the bike nosed over so hard I almost went over the handle bars.

The R/R converts the AC current from the stator to DC and controls voltage. It really shouldn't have anything to do with your problem.
