Got home found
36mm ASII
6.5 Slide
NOZH 3rd
40 Pilot
178 main
Air screw No effect.
FLoat 6.5

I lowered the float to 8mm. It seem to help starting but ran still to rich. No Power. A little bit of change with Air Screw

I just installed a # 7 slide that is From My RB modded A.S.I It
Runs Much better. Very Crisp. Will need g2 Throttle cam for tight single track.
Air Screw has no effect. Even with idle screw out. Idles great. If shut it off sometimes it starts good , sometime it takes 20 kicks

Do you live in the snow ED?

They all look farrrking phat for a 36mm carb. Bailey ran the NOZH in his 2010 300 at similar temps and elevations to myself (1000ft+ 90F high RH%) in a 38mm ASII - 42 NOZH#1 165. I remember thinking the main was super lean on his but it made great power from all reports and no mechanical issues.

A 36mm will generally require leaner jets as there is a greater vacuum/pull of air and fuel through the carb throat.

The NOZ is a 3 taper needle (same tapers as stock N1Ex) with a half clip leaner adjustment). Third taper generally means fat fuelling towards WOT so a smaller main than if you used a single/twin taper.

Your bike is currently jetted very close to stock.
42 N1EF#2 175
40 NOZH#3 178
1 size leaner on the pilot, 2 sizes leaner on the needle diameter, half a clip richer on the needle, and a size richer on the main.
