Hi gavin, I haven't fitted mine yet, but asked this question the other day (for zx9rs).
you have to leave these open to the air, although should fit a filter on the end to stop crud getting sucked in. If you don't the fueling goes
at the window.
I believe its the air bleed jets you need to block, but I haven't a clue where these are - a google reveals nothing for zx9r carbs

Leave the pipe open - it doesn't affect the mixture on ZX6 Carbs.
What have you drilled the mains to, and what notch are the needles on?
On my 2.0 Zetec I have 1.6mm mains with the needle on the lowest [i.e the richest setting] notch. If anything that's a little bit on the rich
side.
I haven't made any other changes to my carbs - mine are re-spaced so don't even have the pipe.
What air filter do you have?

Best to either ask them what the jet sizes are or take one out and measure it - some small drill bits are an easy way of doing this and are cheap
enough to buy.
The jets are easy to remove.

unfortunatly i dont think gbs have managed to ever supply a set of carbs for a pinto that are correctly setup. mainly because its almost impossible
to do.
under ther big air inlet holes on each carb there is a little hole. you either need to block them off or restrict them down to a smaller size.

As I said in my previous post, all you need to do to ZX6R carbs is bigger jets and fiddle with needle position to get midrange mixture right.
Nothing needs blocking up - I think this just applies to ZX9 carbs.
I've fitted a couple of sets on 1.8 and 2.0 Zetecs.
