You could go the final step and test the igniter to confirm your conclusion that it is defective.

I was in the garage today and got the urge to try to start the bike, I needed the fresh smell of exhaust fumes in the morning, but the strangest thing happened. My issue has now jumped to the other cylinder. Now my left cylinder is firing but not my right? Has anyone ever experienced this before? I have a buddy with a running 500r so I’m going to try his cdi next weekend to confirm my conclusion but does anyone know if a “traveling” spark is sign of a bad cdi? I want to use the post now shared but still trying to figure out how to read through it.

Please do ask about anything that is unclear. If it's unclear to you, then it's unclear to others, and I need to fix that.

"Traveling spark", sounds more like something getting reversed during a reassembly to me, that a faulty CDI.

Having a buddy with another EX is a great advantage for you.

But again,

please elaborate on what you don't understand with the post.

Any update on this one? It's been a good read and I need to know the conclusion of the story!

Ninjaguy's gonna jump back in here and be like "Yeah, man! I've already put 3,000 miles on it this month! I just criss crossed the spark plug wires during reassembly."

I had a chance to really look at this over the weekend and what took me a while to figure out was what leads i had to connect and what the readings were supposed to be. Perhaps simplifying the chart so it read a but clearer? I couldn't quite figure out what all the asterisks were supposed to represent. If I am understanding it correctly it should be:

Negative Lead | Positive lead | Ohm reading value
Insert on pin 1 | Insert on Pin 2. | IN

In other words, the chart you created using asterisks as separators confused me. There was too much going on visually for it to be approachable for my skill level.

Had this issue.
Spark plugs and wires can also be subject to inspection.
Trimming spark wires about quarter of inch and new plugs.
New plugs/Proper gap+proper seating.
Had a loopy idle cause one of my plugs started backing out a bit , higher rpms caused it to kill itself on higher rpms until I restated it.
