Thanks ‘Peg. Yes, front left plug wire works the best, and mine is on the 2 stroke setting when I get the correct RPM
. As our bikes use the wasted spark ignition system, there is a spark near TDC on every revolution. That being said, the inductive pulse of the “off power” spark is significantly less than that of the power stroke, as the power stroke requires substantially more energy to fire the plug, being in a compressed, saturated atmosphere versus the relative neutrality of an exhaust stroke.
