I'd also be looking at the HT side of the ignition. The HT loads need to be low as the spark will try and find the path of least resistance. If you have resistor plug caps, ditch them. Make sure your plug gaps are at .025" no wider. On a helmet, the most likely culprit is the rotor. A new rotor, along with losing the resistor caps will probably fix it. You can put a couple of layers of shrink tube on the distributor shaft to help stop the rotor/shaft spark leak path.

My experience is mostly with the crab distributor but all the same things apply.
