Lost spark ignition?

Hi,
Does our bikes use a "lost spark ignition"? Meaning, do the coils fire at the top of the exhaust stroke also? Almost all small engines do, and I've even had a chevy that did also.

This was asked before, and I'm pretty sure the answer was NO. The plugs only fire at the end of the compression stroke.

Yes they do, as the ignition pickup coils receive a magnetic signal with every rotation of the alternator rotor which is attached to the end of the crankshaft.

I think the 3.8 liter V6 in my Olds is a lost spark ignition also.
It doesn`t have a distributor that rotates at half the speed of the crankshaft, but a 3 coil pack with spark plug leads for 2 cylinders attached to each coil.
Each coil fires both plugs on every 360* rotation of the crankshaft, so one spark must always be "lost" in the exhaust stoke of one or the other cylinder.
