MS as CDI replacement on Honda Twin Cyl Motorcycles
Posted: Fri Jul 04, 2014 5:50 pm
I have a 1982 Honda CM450 motorcycle with an un-programmable and likely failing CDI ignition system. I would love to be able to control the spark on my bike with a MS. From what I have read it seems possible but I am not exactly sure of all the details. The engine is a 2 cylinder with 1 shared ignition coil. I've already replaced the factory coil with a GM DIS (AC Delco D555) and this coil is working with the factory CDI. My plan is to use a MAP sensor for load sensing but I am not sure if the VR sensor in my stator is compatible with the MS. All of the setups I have seen on the main MS site use multi-tooth trigger wheels. I have the complete opposite setup. There is a magnet on the flywheel which passes by a pickup coil on the stator so I would get only 1 pulse every revolution of the crank. Does anyone know if this would work? Anyone know of any other spark-only applications of the MS on carbeurated motorcycles? Any input would be greatly appreciated.
