from memory, you'll have coming from the stator, 5 wires,
black
red
brown
white/green
white/red.
the compatible 5 wire CDI's seem to be pretty expensive, even on the 2nd hand market but the more common 4 wire {DT175monoshock, early YZ/IT for eg} cdi's seem to be a lot cheaper with the only difference being they have only one white wire {white/red}.
i've been told, but never tried it, that you can use a 4 wire cdi with a 5 wire stator by running the left over white/green to ground. if the bike should backfire and miss then swap the "whites" around. worth a shot.
hope this helps.
