I just bought this 1987 Banshee from my son and it only fires a couple times every 4 or 5 kicks .I unplugged all TORS plugs and tried the CDI box, the ignition coil, and stator [but not the pick-up coil] from a running 1987 Banshee and nothing changed.I set the gap in the pick-up coil and ohmed all wiring out. The pick-up coil checked good in ohms by the book , but could it be breaking down under load?
