Question I do get crazy I can't get the bike to run lean

2018 GP300 sea level in Stockholm Sweden.
99 Octane it is Sweden so it is not the same as USA RON it is lower.
2% 50:1 Motul 800 Full Synthetic
20 Celsius 68F and a little rain
Needle NEDW#1 at the top, Main jet 168 Pilot jet 40 AS 2 turns out.
Float lever 2mm lower then org. Sparkplug denso W24EsR-u
First I did run 30 minutes then I did clean silencer. Then I did run for 15 minutes and took this pictures.
This track is not so fast and it is gravel and sand average speed 27km/h 16,8mph and am not so fast driver.

I have tested all I can think of.
If I run PJ 38 I do can feel that the engine is to lean. But still drops from the silencer.
I have tested needle N2ZW at #2 still drops.
I have lower the compression by adding two extra cylinder foot gasket .15 and .50 + org .30
That because it was pining when using NEDW#2 and PJ40 MJ175 but still dropping from the silencer.
