The main air jet is a pressed in jet in the inlet bell of the carb. The pilot air jet is the lower left hole looking at the inlet bell, it is a threaded removable jet (Mikuni small round jet).
Now the main FUEL jet is a Mikuni LARGE round jet and is threaded into the bottom of the needle jet/emulsion tube and accessed inside the float bowl. But 140 would be a large jet for that on a version iii carb that would be stock for an LH.Life is what happens while your planning everything else!

If you want to know how the internals work on these carbs, you might take a look at this. It's for BS32's, but it's relevant for the BS34's.I think I have a loose screw behind the handlebars.
