I swapped pipes for a set of de-restricted short tapered TORS...also have a new ignition sensor now running a narrower air gap...with no other changes, the bike was popping like crazy on decel.
So...pilot screws are now 2.75 turn out, and the ACV is re-enabled; those two actions substantially reduced the decel popping.
I may also try disconnecting the TPS. We'll see.
