Find another Suzuki single cylinder model around the same year that has a bunch of CDI's for sale cheap, then find the wiring diagram for that model. If it looks like it will work, take a shot.
I thought my DRZ250 CDI was bad, none on Ebay for cheap but lots of cheap DRZ400 CDI's. I compared the wiring diagrams and they were pretty close, so I borrowed my buddies DRZ400 CDI and it was plug and play and worked. Turned out my CDI wasn't bad, but it confirmed that you could use another model CDI.
