Sweet Spot

Best yet.  I may have finally found it.  

Timing set to 38° BTDC  (corrected)

RS34 Carb Jetting:
127.5 main
 30 pilot
 1.0 air
 3rd needle slot
 1/4 +/- turn out



No popping deceleration

Looks like my plugs. Maybe I should set them and RIDE THE PISS OUT OF HER.

Yes, me brain farts! 

38° that is.  Good eyes, guy's!

Those are sweet, you might try stepping down one heat range. The color change on the earth strap is too close to the base ring. It should be just before the bend of the strap. Mixture is spot on, especially if these are the results of a normal ride. You have nailed it.

Thanks Matt

I purchased a set of IW27 Denso (???) off ebay and had them installed until I found one plug had a problem. 
Through messaging the seller would not confirm the set was genuine Denso and did not offer to replace it, so I immediately removed all of them (ebay item 126044940631):

Those are resistor plugs.  Are you running resistor plug wires, or resistor plug caps (as came stock on your bike)?  If so, you have too much resistance in your ignition.  There should only be ONE resistance element in the system, otherwise spark power will be weakened

Thanks Ed,
I ran non-resistor plug wires and caps with that IW27 set, and currently  with the Nippon Denso W24ES-U in the first post picture.

Running NO resistance element in the ignition system, will make for the strongest spark.  Your neighbors, using the AM radio in their car, may wonder why there is so much static when you ride by, though.  

Yes sir, though there's not much static to be had except at red lights and stop signs. 
Otherwise, it's a brief window rattle and flash of red with a zonic ZOOOOM as I fly past.
