Pilot-screws are 2.75-turns out on both bikes where they're most responsive. More or less and they tend to be more rubbery.
Earlier plug-comparison was back-to-back sessions at Thunderhill several months ago. Both bikes went 20-minutes on East course with ~90% of that time at WOT between 9000-13000rpms. Not sure I can get more identical operating conditions than that.
Stock bike spent all its time in the super-rich top-end zone (1st dyno-chart above). Without any flow-increasing mods, it was even richer than the 12.0:1 AFR recorded on that chart, probably in the 10.0-11.0:1 range. Plugs would seem to show that, if not even richer.
I looked in Dyno-jet kit box and Stg-2 needles with 3-grooves for circlips are still in there. So I've got stock needles in race-bike with no washers.
Gonna hook up the wideband and see how my AFR really compares to those charts above.

after running out of gas, i recomputed to 38 mpg. before i think of checking valves i have stock 98's coming. many postings say the ninja was set up super lean,this opens my eyes quite a bit...
