    Sorry I didn't see this till now ...installing a new control unit did u let system relearn...behind seat fuse panel make a note beside it or below it is a toggle switch this is learning switch if I remember correct toggle is up and by clicking it to middle or neutral and turning key on no crank for 5 secs and you should hear control work and turn key off ...Now crank machine and use a 6mm allen wrench on control arm to set low idle with idle dial set at low ..then turn idle dial up to wot and adjust 6mm again to wot or till it hits throttle stop ..and lower rpms and see if it will turn off by key switch..repeat if it doesnt
