Hi, I would really like to know if someone might have a clue to what this little adjuster screw does...

Its a 2003 R1

I adjusted this one day when I was after the idling adjuster... stupid I know!

Since I played with this my bike has never idled correctly when cold. So I assume it must be something to do with the cold start fuelling or something.

I attached the pictures so you can see which one I mean...

Is there any way to get the correct adjustment???

Many thanks

Youll have to wait for some of the R1 fans to come on and sort ya !

I know feck-all about this bike, but...

My guess would be that it alters the air/fuel mixture. I've done this myself before, when seeking the idle adjuster. You can take it to get professionally tuned (unless you have the equipment yourself), or get a Colortune kit and DIY - Not as precise as the pro kit, but basically good enough.
