Do not mess with the air screw it only adjusts idle.

FMF says #260 main with the air box lid on, if you premix at 32:1 then #270.

Needle on middle clip, float level 20 - 21.5 mm.

How clean is the air filter?

Plug chop to confirm.
 
Any changes with breathing require re-jetting, confirmed by a plug chop.

If you put the lid on, you need to change the main jet to a smaller number.

Did you change the jet?

Clean the air filter before you plug chop.
