Here's what I did (as per the Dynatek people I spoke to)
1. install the automatic advancer ensuring the "F" mark is lined up with the engine case mark, along with the rotor. The rotor magnet is facing to the rear of the bike.
2. remove the #4 cylinder spark plug, reinstall the lead and leave the connected plug outside the engine making sure it is grounded touching the engine.
3. install the pick up plate loosely, rotating it counter clockwise all the way till it stops. Turn on the power.
3. rotate the rotor clockwise all the way till it stops. hold it there.
4. slowly rotate the pick up plate clockwise until the cylinder 4 spark plug sparks.
Done.
The positive to the pick ups are connected to the tail light.
The negative for the pick up 1 and 4 are connected to the negative lead to the coil firing 1 and 4
The negative for the pick up 2 and 3 are connected to the negative lead to the coil firing 2 and 3.
I do get spark for cylinders 3 and 4 (assuming the same would be the for 1 and 2 since they are suing the same coils).
The coil located on the clutch lever side is for cylinders 2 and 3.
the coil located on the Brake lever side is for cylinders 1 and 4.
Sound ok? I'm really stumped.
Thanks

Using one coil? Going to the tail light?

NOOOOO !! Ignition should come from the Main ignition fuse. Not sure if it would prevent it running but it is still wrong.
I run a z1000 up without any wiring loom fitted but just with a battery, an inline fuse and a few wires. Get a temporary 12v + source from the battery and protect it with a 20A inline fuse.
Apart from the early 70's kz with just one main fuse, later 3 way fuseboxes are head , tail and ignition, You could even remove both head and tail fuses and still run the motor.
I do get spark for cylinders 3 and 4 (assuming the same would be the for 1 and 2 since they are using the same coils).
Getting either inner or outer cylinder firing , 1,4 or 2,3 suggests one coil or pick up is defective.
Getting only 3 and 4 firing means either you have mixed up your plug leads, or as above with mixed up plug leads.
Get new 7mm silicon wires , plugs and non resistor caps to eliminate this part. Does the tacho twitch when you switch it on?
Nice 750, those black wheels really work. Less is more sometimes.

Power to the Dynatek is coming from the 12 volt power to the tail light, There's a note about this in step 11 of the Dynatek instructions.
I did a reading with a multimeter and it does read 12 volts.
When I say cylinders 3 and 4 are sparking I'm taking both plugs out, attaching the leads and then letting them hang outside the engine touching the case for grounding. When I attempt to start the engine, both spark plugs spark alternately. I was assuming that since this is happening, cylinders 1 and 2 must be doing the same.
I have the three way fuse box.
I don't have a tach like the OEM part, I have a Vapor installed.
Thanks! I did all the work myself so far.

1) Rotate engine and aligning the 1-4 F mark
2) Rotate Dyna S pick up coil plate fully counterclockwise within the slots of the plate (make sure the screws are installed but not tightened)
3) hook up a test light to the LH side pickup trigger and slowly rotate the Dyna S plate clockwise and stop when the light comes on
4) Tighten the screws affixing the Dyna S plate to the engine
The Dyna S instructions specify holding the rotor against the spring and aligning the light to the mark to the right of the F but in my experience this is more trouble than it's worth. If you have the unit timed properly to the F mark without holding the rotor you are fine.
Oh and one other thing, the Dyna S wants coils with between 3-5 ohms primary resistance and the stock KZ coils are something like 1.8-2.8. You might want to consider adding a ballast resistor to increase resistance up a point or so.
