As the title suggests, I'm trying to get my idle mix right and failing miserably.

I keep fouling plugs, initially they were just black. I stripped down the carbies, gave them a nice bath, put them all back together and they bike ran much better - except at idle.

So now when I foul plugs, they come out nicely brown, but with a wet layer of oily fuely gunk on top. She runs beautifull from 3k -12.k but below three she tends to run choppy, and the front cylinder is a bit intermittant.

If I'm stuck in traffic or at low speed she starts to struggle with idling and I have to rev her to keep her alive.

So back to the air screws. I'm trying to follow the procedure - MC21 + TA22B. I take the screws to 1.5 turns out. then try to adjust from there. The only problem is that nothing happens when I turn. All the way in, or completely removed seems to make no difference.

The previous owner fitted a Tyga System and removed the airbox for pod filters. I won't go into jetting, but just say stock slow jet, slightly uprated main jet and power jet still seems active.

I have done the wiresplice and that went great at operating Revs but this niggling Idling/Fouling problem won't go away.

I have a computer in my garage and I've currently got the tank and fairings off cleaning, poking and prodding so any suggestions would be great.

I've got her running so nicely it would be a shame to have to take her to a mechanic for something as mundane as idle problems.

Cheers
