If it idles well, don't change the pilot. Just focus on the main and then the needle. My two cents.
Coming off idle, those carbs use an accel pump, right? Have you checked that?
And by the way, this is something we all go thru with these bikes. The compression drives 70% of the bike's operation, and the rest is timing/ignition and carbs. I might have missed an item or two but you get it. Getting everything right is a time-consuming affair. Or better, a love-hate relationship.
