well, acording to my pile of shite, dropping to bits haynes manual, they are :

Pilot = 12.5

Main = cylinder 1+4 = 132.5
Main = cylinder 2+3 = 130

thats for the california and usa models, uk differ slightly

pilot screw settings are blanked off on yours, but if/when you drill out the blank, the settings are :

Cylinder 1+4 = 3 turns out
cylinder 2+3 = 2 3/4 turns out

Float height = 7mm +/- 1mm
Fuel level = 15.5mm +/- 0.5mm

as you can tell, thats the book speaking, as i also know fuck all about carbs !!!
