Its an air jet, buy opening it up slightly you are letting in more air not fuel.
More air should lean things off a touch.

All done on a very slight scale if you're going 0.9 to 1.0mm tho

carb setup at present is all stock jets apart from 2nd stage drilled to 1.3mm and afrs are flat out in 4th gear are 12.9

You said you tried a 0.9mm and it was too rich so id drill it out to 1.0mm try it, still too rich, do it to 1.1mm.

I wouldnt go bigger than 1.3mm on the 2nd stage tho.

Suck it an see.

ok i will give that a try what the best afrs to be at ?

Everyone will tell you different mate.
High 11s low 12s @ WOT seems most accepted.
