Im looking to convert a 6volt Honda twin to CDI any ideas?

Old bikes had very weak ignition coils and I'm sure yours is one. There's nothing wrong with points and I seriously doubt they are the real problem. With a 360 degree crankshaft, I imagine you have a single set of points and a single twin lead ignition coil and what you need is a twin lead 6 volt automotive coil but I'm not sure they make them. 12V yes, 6V??? If you have two sets of points two coils, then you have a 180 degree crank and putting on two larger coils will do the trick. Better coils will provide more powerful spark, easier starting, better running, longer plug life and better able to tolerate off spec fuel-air mixtures.
