The bike is off the operating table

After experiencing some solid engine ping from 3500 - 5000rpm of wide open throttle 2 weeks ago I decided to do a little surgery on the bike. I just spent the last week doing the following:
  Removed the CA emissions junk
  Removed the carbs, jets and needles and cleaned them up real good
  Adjusted the float levels to the high side of the specifications
  Performed a valve adjustment
  Synched the carbs
  I just tested it last night between storm systems. Wow, what a difference. Although I know I shouldn't do this, I can pull the throttle wide open at 3000rpm in second gear with no pinging at all. I'm glad it worked out so well. I would have hated to do all that work with no positive result. In addition to the lack of pinging the engine is much smoother now. 6000rpm+ doesn't feel rough at all like it used to. My idle is also rock solid now. The carbs didn't seem particularly dirty when I cracked them open and the float levels weren't very far off at all. I guess the carbs are just amazingly sensitive to variations in their settings. Many thanks to the folks on this list for their help.
  I'm in the market for an ignition advancer now that the engine is running as it should. Any recommendations?
