Kz750 LTD woops, what are they?

Hi anyone know what these are, and where they should have been in my carbs?
After assembling a full set from two sets I have 4 of them left over(not so assume I pulled them from the original set before I went looling for a donor set.
Oh,And both banks were ment to be from an LTD.
My Hanes manual didn't seam to show them???
Bit stuck without even knowing what they are?
ThanX

They are plugs for the pilot jets? You need them in otherwise your bowls will spew gas everywhere.

I don't have a good pic but you can kinda tell where they go.

Awesome! ThanQ
Probably saved me some real agro there! Lol
