77 CB750F stock air screw position? (real world)
« on: August 19, 2012, 07:50:37 PM »
All the references I see for the PD41B carbs on the 77 750F show that the stock bike had the air screws set at 1 turn out. However, most of the threads I see mention either 1.5 or 1.75 turns out.

What setting are most people here using on a stock setup in the real world? I know every bike is different, but just trying to get a baseline for my recently rebuilt carbs.

Stock air screw position on a stock 1977 CB750F is 1 turn.
