You do not want to fire a coil without a load on it. A good way to check out a coil to is to swap it with another. To kill a coil but not damage anything you can put a piece of heater hose in between the coil and the plug and touch a grounded test light to it to kill spark at that coil, or just unplug it at the primary side. You could maybe do that and see if the misfire gets worse. If it does, it could be fuel related or valve or head problem.

Most sports require one ball, motocross requires two.
Racing isn't a matter of life and death, it's much more important than that.
