Default Single fire Or Dual fire ignition system

All

Does anybody know For Sure weather the New 04-05 sportsters use Single fire Or Dual fire ignition systems. I have heard the new sportsters use the Single fire system But have also seen posts that state All sportsters except the 1200S model use the dual fire system. Does anybody know for sure. Thanks...

Here is what a 05 Sportster service manual says:

"The ignition coil is divided into front and rear coils that fire the spark plugs independently, one cylinder at a time."

AKA single fire

As for a good article relating to this:

Then you'd be wrong.
