Also, pilot air screw adjustments likely won't produce much effect on a carb with a less than perfectly clean as-new pilot circuit.

Sounds like a braggart to me. If he did all that work then why does it have the stock jetting? I'd discount anything he says at this point.
I think Patton may have hit on it with the vacuum leak.

The spray always backfires. ALWAYS!
The choke (enrichener) circuit is a separate circuit inside the carb, which is different from the pilot circuit.
It might also require some tlc, but generally, in my experience, causes less problems than the pilot circuit.

There are workarounds such as heating the hoses with a hair dryer or heat gun, but the best solution is a brand new set of soft sexy airbox hoses.

Bike runs fine...kinda rough though after I kill the choke. I checked for vacuum leaks but don't see any. All my caps are on the "carb holder" aside from one that is pulling vacuum for the petcock. Then it has the four overflow tunes for the bowls. The only ones I'm questioning are the two towards the top of the carbs. They make sense since the carb needs to breath a little but I could be wrong. Here is a picture
