Mike,
Right you are, it is a cheap coil. You didn't insult me.
I never thought of the coil being the issue, but now that I think about it, you may be right. It is the only piece left over from the test running of the motor that was not up graded. I will purchase a new MSD coil and give that a shot. I'm pretty sure I'm not hitting the rev limit, however I will check that next. I am running the tach off of the MSD box, so I hope the gauge reads exactly what the box is putting out.
