OK, let's start out this way. All Banshee flywheels are the same and will fit all RZ350 cranks. All Banshee stators will fit your RZ cases. All Banshee stators and CDI boxes will work with each other as long as the connectors can be connected together. It's basically 87-94, 95-96, and 97 and newer. You can change the connectors as long as you match colors. Getting back to the RZ, to make it right, you need flywheel, stator, wireharness, CDI, voltage regulator, power valve controller box, and powervalve servo motor with cables. If you just want to make it run for now, I would lock the powervalves in the open position. Your low RPM power is going to suffer slightly, but shouldn't be too bad.
