Over the past three years I have bought electronic ignitions combined with regulator/rectifiers from Charlie's Place. They were for a '68 CT90 (6v), a '64 CB77 (12v), and a '66 CB450 (12v). In all three cases they were easy to install (I only had to call Charlie one time and he was super helpful) and they worked perfectly. I get better spark and easier starting in all three bikes and they run great. Some people like points ignitions but the reason they aren't used any more is because they wear out and are undependable (in my opinion). I know they are a little pricey but cry once and you will be happy in the long run.
