Hmm So wonder if you wrote Taylor and told them your problem and maybe linked it here they would send you a new set? I was recently looking at a set of their wires I think over @ Witch Doctors. They aint cheap for sure $40 or so.
On the why @ under 3K rpm? At that rpm the motor and spark are for lack of better term "lazy" Once RPM goes up there is a bit more power pushing the spark and it can then push thru the resistor in the plug.
