I think you need to do a throttle body sync starting with removing and cleaning the BBSs.
You'll have to redo it again after you adjust the valves but it's probably better to get the idle problem fixed before you start changing too many things at once.
I could be wrong but I do not think the valves need to be adjusted yet. No chatter. Bike starts and runs fine. As you said, I do not want to start changing stuff to just change something. What is the BBS? Where is it located?
