KLR, pilot needle direction

I've seen lots of conflicting information on the googles about which direction to turn the carb needle to richen the idle. Some say it's an air bleed, so turning the screw out leans it, some say it's a more normal pilot adjustment where turning the screw out richens it. Anyone know for sure?

If the adjuster screw is located between the slide and the engine, it is usually a fuel screw, turn in to lean out the mixture.

If the adjuster screw is located between the slide and the air cleaner it is usually an air screw, turn in to richen the mixture.

+ 1!

Regardless of what Kawasaki might label the part, it's a "FUEL SCREW" on the Keihin CVK40.

Counterclockwise rotation fuel-enriches the mixture, clockwise rotation fuel-leans the mixture.

Thanks! And also, great rule of thumb! I'll have to remember that one. That's saved me a lot of hassle trying to determine that experimentally.
