With no mods....start at 2 turns out and fine tune from there.

The "Factory Specs" according to the Suzuki Shop Manual says "Preset-varies" for the PILOT adjustment screw (its not an air screw, just so ya know) But, as said, 2 turns out is a GOOD baseline setting to start with, and if youve got pods/pipe, i would actually start at 2.5 turns out...

To answer your curiosity, I have seen the factory settings between 3/4 and 1 1/4 turns out. These were pre-set to meet EPA regulations at the expense of driveability. Not sure if they were set while on the bike or on a test bench, but they supposedly used some kind of analyzer to set them "right", then they sealed them.

By setting them a minimum of 2 full turns out, you allow enough mixture for the engine to actually run somewhat properly.
