Information for those who will follow this thread in the future.
After installing TBS needles with no shims, based on a earlier statement in this thread, I found via the air/fuel gauge a very lean running motor. Ratios started to climb to 18 to 1 before I backed out of the throttle.
'06 SM with T100/America Wheels (D&D's, 10.5 to 1 Wiseco pistons, TTP Igniter +3, K&N PODS, 150 x 40, FZ1 springs & TBS needles w/3 shims)
