Hey All,
Hoping to find some expertise here, as I for sure am not an expert or a mechanic - I've been teaching myself a lot and have been able to trouble shoot, but I'm stuck right now.
Long story short, my bike was running perfectly. I had changed out the plugs, installed new spark wires and fuel lines and filters. It ran better than it ever had since I've owned it.
THEN, I decided to go a step further and started to made some aesthetic adjustments - new mirrors, new brake/clutch levers, etc (a lot was rusted). Everything came crashing down when I tried to install a new, more modern tail light. I now know, that these old positive ground bikes won't work with LED lights. So, I switched back to the original. I'm assuming the issue is electrical as trying to swap out the tail light is when it decided to not work. All of the electrical seems to work. Lights, horn, tail light, etc. I have a Pazon electrical ignition. I tested it (using the directions from their website - crossing the wires with the plug grounded to the cylinder and saw a spark). So seems to me that works. When I ground the spark to the cylinder and try to kick-start, I get nothing.

Anyone have any thoughts/suggestions?

Run a jumper wire from battery negative to the power feed wire on the Pazon box(white) after you disconnect the y/w feed from the harness. You are then "hot wiring" the ignition and completely going around the bikes wiring. It's a good idea to put a blade fuse holder with a 15 amp fuse in the wire along with a switch. Makes it easier to shut the engine down instead of trying to pull the jumper wire off as you are bypassing the ignition switch. If the bike starts easily with the jumper in place then you have a voltage drop somewhere in the wiring harness or ignition or kill switch.

Charge the battery. You may have discharged the battery to a voltage too low for the EI.

After eliminating electrical concerns: Did you do anything with the carburetors or the throttle control or throttle cables? Maybe a throttle cable is hung up? Remove the air cleaners and see if the throttle slides are dropping down to bottom. You might try spraying some ether into the carb mouths - if it pops and then dies, your problem is fuel-related.

Thanks everyone.
I don't think it's an electrical issue.
I actually do get a spark on kick. It must have been too light outside for me to see when I originally posted this.
Mark Z, my next step is trying your recommendation on the carb/throttle cables.
The throttle doesn't feel like it snaps back like it should.
That or maybe the jet has a clog so will try cleaning that as well.
I'm almost certain it's something to do with the carb. Everytime this bike doesn't start it winds up being the carb.
I might have just tricked myself into thinking it was electrical.

OK, if before the THEN in your first account it was running fine, then after THEN it doesn't, the stuff you changed between the 1st THEN and the 2nd THEN have to be highly suspect.
Your info is about as good as btour, eg does your plug spark or not? Please use a known good battery and give a definitive answer.
When you start wandering around possibilities, I lose hope.
Lets see what others may say.

The spark needs to be blue not yellow.

I don't understand why people are so reluctant to do the hot wire battery to ei box test. It's a very simple concept and will tell you in five minutes whether you have an electrical issue or to look elsewhere. First diagnostic step I take. Maybe they like to see their thread grow.

With electronic ignition it's typical to get a yellow spark. I've seen this on two bikes after converting from breaker points, all else equal (and yes, a good charged battery). Both bikes started and ran without issue though.

Was that with two 12V coils in series?

Even connect it to +&- of the battery in their car.
