First plug chop after carb rebuild and adjustment

The nice golden hue has went away on the pipes, I have checked mileage yet. I needed an ice cold beer after this fiasco today. What would cause the 8K stumbling?

I'd be happy. Keeps the pipes from turning blue. How's the mileage?

Is this fixed by turning in the A/F screw? Or should I change the jets back to stock? They are the jets that were in it when I bought it

Maybe a titch rich on all of them.

Hey guys, after several attempts and adjustments of the carbs after rebuild I think I have it lined out. I was a bad GS owner and have neglected the maintenance until this year. So here's what I did

1. Carb rebuild, new O-rings, gaskets, A/F screw turned 2.75 turns out on all cylinders floats are all within spec, new fuel line, petcock is good no flow on reserve or normal. Prime has a great flow of gas .
Jets are a 120, 45, 180, K&N air filter and stock exhaust
2. New plugs and wire caps
3. All new fluids, greased all the bearings, new fork oil, sprigs, brakes and braided lines

Now that all that stuff out of the way here are the photos of the plugs after a mile run, I ran the bike pretty hard only problem is around 8-9k the bike kinda studders but still continues to pull to redline just not as hard like its hit a wall

Plugs are 1-4 left to right in all photos gaps are .7mm
also I have all new o-rings in carb boots and new air boots
