How can i modify my suzuki gsxr 250 ignition system to fit some other CDI unit?

My CDI is shot and since im in a place where its virtually impossible to get a replacement, what kind of modification can i do to get it running again? I used the simple cdi idea i found online on my moped and its been fine so far but this one is 4 stroke and 4 cylinder with 2 pulsers. Any thoughts would be greatly appreciated.
