I'd try a new plug! Obviously you're getting enough juice to create a spark. Probably the plug has some carbon on the insulator tip creating an easier path to ground. I have even had some brand new out of the box (Champion) plugs that were defective.

Has the bike ever started properly since you've had it? In other words, what's the history of this problem.
Is it possible the coils are grounded and the spark is jumping from ground back up thru the plug? I don't know if that can happen or not. There are lots of good electrical folks here. Maybe Earl will see this and help you out.

If I understand you correctly, you are not getting the spark across the tip to electrode, but when the plug is placed near ground, it sparks from the tip to ground.
Check your plug gap. If the gap is too wide, then you might not have enough voltage to jump the gap. If your gap is already at the smallest recommended, then you may have weak coils. Other possibility is hairline cracks in the electrodes, or a non-conductive grease or other contaminant on the threads and/or electrodes (motor oil is non-conductive).
