The decel popping is fine now. I like to hear some decel rumble and pops (and should) with less restrictive exhausts. They felt after many similar runs, the 125 mains are fine. Changing to the 45 pilots took care of the loud popping without having the pilot screws out too far. They prefer keeping the sniffer showing 3%, but mine did end up a little richer (4-5%) at idle at the best run setting. On the next dyno the initial leaning should be gone. It still might lean out a bit near max. throttle, but if it keeps the bike the best through the range I mostly use, it's fine with me. The bike does run noticeably better than the way it was set up when the last dyno was done. I guess we'll get a better picture on the next run. Meanwhile, I'm having a blast riding the bike.
