Default z400 pilot jet?

I have a ct pipe an a k&n filter.
I am geting a slight dead spot between 1/8 and 1/4 throttle.
I have a dynojet needle, irt was on the 3rd clip, I changed it to the fourth and did not get rid of it.
I have changed the mainjet a couple of times(between 150 and 165) did not efect it.
I know the main jet mostly efects 1/2 to full throttle wanted to try it anyway.
What are the two other jets in the bottom of the carb, what one is the pilot jet?
Does anyone know the stock pilot jet size?
I think that is my proble, but Im not sure.

Also which way do you turn the air screw to richen or lean it.
When you drop the needle down(raise the clip) it leans it out right.
I used to know a little about this when I had a banchee, but it has been to long and I forgot it all.

Yes I am happy with the CT, fits great, looks good and pulls a lot harder through the gears.
I does give it more of a powerband feel though, More of a mid range hit.
Oh yeah it is pretty quiet too.
