Read the "carbs 101" sticky at the top of this form page:

Needles don't turn, they have clips numbered 1 through 5 and are found in the top under the black covers in the diaphrams.
Fuel screws on the bottoms of the carbs are turned, 1 through 3 turns
Mains are the jets inside the float bowls that are in the gold shroud, right side is one size larger than left (ie 140L/145R)
Pilots are the smaller jets inside the float bowls. OEM is 22.5 but most up to 25 when adding a pipe and filter.
