RFI would cause a problem if you ran a helmet headset. EMI causes problems with signals being sent to the EMS from your sensors. As would any electromagnetic pulse. The other problem that could arise would be cross firing causes by “Induction cross-firing results from the magnetic field produced when an electrical current passes through a spark plug wire, causing two cylinders to fire at the same time. If crossfiring is allowed to occur, one cylinder has the spark plug firing ADVANCED 90° from the proper time.”
