The pocket does not have to be milled out of a billet.
     could be laser cut from sheet stock in three pieces. Front cover
     back cover and spacer.

     Since there is one slide throttle  per intake runner cost can be
     cut by a quantity order of all the pieces.

Paul, The leading edge of the slide throttle needs a slight chamfer.
The original carburator versions used on to pull gas from the pilot
jets, but a chamfer seems to help idle with FI if I remember some
of Kawasaki's old data. (The chamfer is about a 30° about half
way across the throttle blade. The wide side is toward the bellmouth.
