The black wire for the kill switch on my cdi is broken off is there any other way to fit a kill switch without replacing the whole CDI unit

If it's broken off at the CDI unit then you will have to replace the unit, hard to remember if where the wires come out is plastic or resin, if it's resin it may be possible to chip it away enough to get a new wire soldered on & covered back over with araldite or similar. Could be worth trying as the worst that could happen would be you need a new unit

Might try tapping it into the red wire, not much to lose here sounds like.
