I have a book for 93 and it says 5/8 turns!
anyone know if 91 is different?

machine is bone stock

The repair manual states the 5/8 turn as a starting point. When you get where you're going warm up the engine and then raise the idle to 2000-2500 RPM. Adjust the air screws out until the maximum RPM is reached. After that, turn the idle back down to the stock spec, about 1500 RPM off the top of my mind.
