Alright I got the starter working fine, next up is the coils. I only am getting spark on two plugs clearly from the same coil. Here is where I have an issue between the D1 and the H2 models. On the D1 it shows the white/red lead from the reg/rec connecting to the postitive battery lead from that connects the battery and sTarter relay. On the H2 model it shows the white/red lead connecting to the ignition switch. I currently have it in D1 setup, should I switch? Why would this one connection affect only one coil and not the other?
Thanks,

Wow, I never noticed that. The 550 F (82/83) is also wired like the H as you describe.
The difference in the two designs is basically the location of the main fuse. The D has the fuse between ignition switch and battery/reg/rec whereas the H puts the fuse between the battery and ignitionswitch/reg/rec.
It looks like Kaw changed their standard practice after 1981. (I often will put a fuse in both locations because it makes it easier to troubleshoot shorts.) Personally, if you are only going to have one main fuse, I think the D setup makes more sense. In the H setup, if the main fuse blows, the reg/rec is still supplying power to the ignition, but the battery is out of the circuit. This is bad. Without the battery in the circuit, the reg/rec can lose regulation and melt the electrical system. (it's happened to a few people on this forum.)
Stick with the D setup or put a fuse in both locations.
This is mostly a charging system issue. This really should not affect your ignition coil issue.
To check your ignition issue, first make sure both coils are getting 12v. When the engine is not turning, both contacts on the coils will have 12v.
As the engine turns, your ignitor grounds the negative side of each of the two coils in succession. The engine has to turn at normal startup speed (or faster) in order for that to happen. Turning the engine over very slowly will not cause a spark to happen.
If you have power to both coils, and you still only get spark from one coil while turning over at normal speed, swap the (small) wires from one coil to the other and see if the problem stays on the same coil. If so, then it is likely a bad coil. If the problem moves to the other coil, then it is a wiring problem, or a pickup problem, or an ignitor problem.
