Under the carbs are the inlet tubes. There should be some short stabbings with rubber caps, remove the caps and connect your balance gauges.

This isn't on a FZR400 RR but I'd imagine it's the same setup.

I saw some screws attached to the inlet, near the Allen bolts that attach them but they seem welded on LOL, can't seem to unsrew the bastards. There are how ever some tubes, overflow looking types hanging from the carbs that are not attached to any thing, 4 of them, 2 plain short ones about 6m and another 2 with caps on, not connected? Lovely clean bike by the way marra.

on the rr/3tj models the vacume pipes attatch to the small screws on the manifold boots (the rubber jobbies) between the carb and manifold
the adjustment screws are between each carb ie 1&2 2&3 3&4 and a proper fiddle it is

edit pretty much what laminator said but the manifold boots are rubber, which is a shame as they perrish and theres screw not rubber caps
