Honda 200 models CDI upgrade?

[dansvan]

What can we do to up the performance of the factory CDI? I see Dennis Kirk sells a few performance CDI boxes but for the machine up to 83 and then like 86-87. Is one factory model better than the other? Motorcycle CDI's on a ATC?

i was wondering this myself, i have seen performance ones for an xr200 i and i wondered what the difference is, and can we wire them up.
