Do you have a spoke magnet that's twisted out of plane and is hitting something? A valve nut that's still on that might be loose?
deep sky's comment is also a good one - if your RD needs some adjustment with the barrel adjuster to get better alignment with the cogs?
Lots of options
I'll have it out on the road next week. I'll try to get it out this week just to listen for the sound.
I do not have a spoke magnet.
May you please explain the loose valve nut? Both valves are currently closed.
The RD definitely needs some adjustment. I've watched several videos, but I'll save it for the shop tune-up. The shifting down is not snappy, in fact it even lags several seconds. In some instances I have to shift up and then back down.
