Instead of the MSD brand Multi-Spark Discharge system I would highly recommend a Mallory Hyfire 6A, 6AL if you don't have built-in rev-limiting. Mallory uses an all-digital processing system as opposed to the "MSD" system that's analog. I've seen much better reliability from the Mallory box, IMHO.

Just remember to upgrade to a better coil!

As to the stock/aftermarked msd argument... People always say "Well if it's so much better why didn't it come stock?" Very simple answer: Expense. A CDI ignition "works fine", where as the MSD system "costs more".

Also improvements you'll see with a msd system: Cleaner lower-end emissions (for smog testing reasons), slight increase of sub-3000rpm torque, some claim to feel a smoother transition from 2k-4k rpms, smoother idle. You can also get away with running a little richer in the lower RPMs, that's another benefit of msd systems.

But that's all icing on the cake. The best advantage imho is that you're putting newer and better technology in-place. Until you get to single coils on each hole.
