The '81-'82 CB125 had pointless ignition, and these were the same parts as the early ATC200s' used. The CB125s were still 6volt, so I would assume with pulse coil, advancer and 2ndary coils all of the same type you should be able to use those items.... I may actually have a pulse coil and 2ndary from a '84 ATC200S.... if you cant find anything locally, let me know....
