Well Al, I finally got around to checking my plugs with one shim under the TBS needles, a bit too rich. So, I pulled the shims, and while at it, turned the Pilot mix screws in a bit (the right is at 2.75 turns, left at 3 even, as the right seems a tad richer than the left. I already ran it up the street at WOT and didn't notice any issues up to 70mph with acceleration, will ride again tonight and see what leaning up the pilot screws (they were at 3.25 turns) does, I suspect it should be fine, hopefully no noticeable difference on popping (which was up till now much diminished with 3.25 turns and TBS/1 shim setup....
