When you mention 'dual fire', is that the same as: 'wasted spark' (like on inline 2, 4, or 6 cylinder bikes)?  If ignition is triggered by crank position sensors, which I think they are, then it's likely a wasted spark, no?

Dual fire shoots spark to both cylinders at the same time from an single coil. Most of the spark goes to the cylinder under compression while a smaller bit go to the exhaust stroke. There is some "wasted spark" as a result.

Opening up this topic for discussion.

Considering the age and differences of our Drifters (1500 and 800) - do our bikes have single or dual fire ignitions? Both the same? Different on 800 and 1500?

If you know the answer(s) post your info here, references if you have them.
