Default Idle Adjustment Screw Location?

Hey, I Have a 1988 Suzuki Katana GSXF 600. And it runs greats, just the rpms are at like 650-800. And I want to make it 1100-1200. Where on my bike is the Idle Adjustment Screw? Will I have to take off my fairings?
Thanks! Kyle

If you're sitting on the bike, it should be accessible through the opening on the left main upper fairing. It should be a brass colored screw with knobbies on the edges and a phillips head screw point in the center. It should be connected to the bank of carbs by a tension wire that is covered in black rubber. Right turns up the idle.

^He's got it.

EDIT: Also, if you find that the idle screw is not changing your idle at all, then you probably have a clogged jet in the pilot circuit and it might be carb cleaning time!

For the most part, except the new Kats have plastic knobs instead of the metal.

The choke lever adds lots of extra fuel, so yeah... won't have much effect with that on when you adjust the idle, but...

Never touch the idle adjuster unless the bike has been fully warmed up.

If you find you "need" to adjust it other times because the bike won't run or stay running, then you need clean the carbs.

Blasty from the pasty.

I'm pretty sure on the 88 the screw is in the center of the #2 and #3 float bowls.

If your adjuster fell out (any model) the easiest way to replace it is to pull the carbs, stick the adjuster back in, and turn it to the right.

Thanks for the quick reply... I dont need to replace mine, I just have to screw it back on... Is it possible to screw it back on without pulling the carbs? so what your saying is its in between #3 and #4, Im assuming thats the right side of the bike correct? would I be able to see where it screws into without pulling the carbs? Sorry for so many questions.. Im still a newb to the mechanical aspect of bikes, I know cars. LOL thank you for the help, I greatly appreciate it
