What does this knob do (ooeerr etc etc) VFR 750

[swampy]

I have recently got a VFR 750 ('96) and on the left side under the middle fairing (but easily reachable from the seat) is a plastic knurled knob about the size of a penny piece.

Does anyone know what it does ?

There seems to be a black tube leading from the back of it to the bowels of the engine somewhere. I'm guessing fuel tap or something along those lines, but as only one tube in, I'm a bit confused....

Cheers folks

I believe it is the tickover control for the carbs if my memory serves me right.

Idle speed or rear preload? Turn it and see what happens.

Idle speed sounds logical, I know its not the preload control....

Thanks gents...
