My bike is not transportation, it is a respite
This bike will not run with the choke fully closed. With these carbs, if the choke is fully closed, you have blocked off all air flow into the carbs. You need fuel, spark, and AIR for combustion to occur. When I start my bike cold, I only close the choke about half way.
A cold bike tends to run lean because the fuel is not fully atomizing. A lean bike tends to rev up. Closing the choke lever partially restricts the air flow into the carb, causing the mixture to be richer. I only close the choke enough to keep the engine from revving up. I only have it partially closed for about 30 seconds.
Somewhat related to this, if you are riding and the bike starts revving up at a stop light or popping while you are riding, you are probably out of gas. A revving engine is a sign of your mixture leaning out. This happens when you don't have enough fuel in your carb bowls.
Next time you start the bike, tap the headers with your fingers. They should warm up about the same. Yes, eventually they will be so hot that you can no longer touch them.
I just pulled my pistons and found a broken ring. I had no idea. I just knew it was burning oil.
