SUCCESS STORY!!!

So was it the ground or the needle valve seat?

I am not quite sure.
I put the carbs back on after the 4th try and it still didn't run great. I was ready to push the thing off a cliff. So I went back and triple checked the ignition again. I was getting spark on the bad side. But I was wondering if maybe the CDI box was messed up like Kurlon mentioned. The only modification to the wiring harness was where the guy before me changed front directionals to LED ones. Then I saw a broken ground wire, but it was not in the group of wires for the ignition components, it appeared to be in a group going to the front dash, maybe for one of the lights in the tach or speedo? I would have to pull apart a lot of stuff to trace it all out. I fixed it. Logically I don't think it was that wire. If it was anything electrical, I think it would be more likely the fact I was working on the wiring harness, disconnecting and reconnecting things, and maybe I somehow fixed a loose connection that was effecting the timing on the bad cylinder. It doesn't seem likely given the simple electrical design of the system, but who knows.
So my vote is the carbs were the main problem.

Awesome man. glad to hear it's all good now. oring could have had some affect, or you just finally dislodged something that was plugged up. either way, I'm sure you guys are excited.

I haven't messed with the electrical on the GS much but a bad ground can cause all sorts of crazy issues, and get worse under higher load, which sort of fits the same symptoms as carb issues. Either way you have some very shiny carbs now!

Your son is very lucky

I'm the lucky one. My son is the best. Great kid and a hard worker. He is working two jobs to earn money, plus volunteering at a museum.

Now teach him

Practice Panic stops

Target fixation , go where you look

Lean lean lean the lean some more

Panic slow to 10 then swerve

You pay for attgat

My boys are NOT being motorcycle supported they will have to be 21 and pay for themselves
They have mini dirt bikes
