There should be 1 plate like that, on the top of the stack. But, from 2002 until 2006, Honda's parts fiche number was wrong in the published shop manuals (online parts lookups) and they were being sold as all 6 (or 7) of the plates. This makes the clutch slip.
Also: the slots must be 'pinwheeled' out to let the oil slip out, otherwise it holds the oil in and the plates slip. On the 750, as you look at the clutch plate going over the top of the clutch, the slants exit to your left (rear of engine).
The plate thicknesses are often screed up, too, because of incorrect vendors. Measure each plate: it MUST be thicker than 0.128", which is the worn-out lower limit. Modern superbikes use plates that are the same exact shape, but are thinner at 0.127" brand new! This makes them slip...
There should be 7 cork plates in the stack, and the inner face of the top pressure plate should be even with the tops of the clutch fingers. If it is sitting down in the fingers, the stack is too short and thin plates are in it.
The plates you want will measure 0.138"-0.140" thick when new: PartsNmore has the correct ones. You can use one of the slipper plates on the top of the stack like Honda did: this will soften the final closure of the clutch from a stop-to-moving startup. Or, you can install a square-cut cork style instead: take note, though, that this top plate has wider outer fingers than the other plates. It is unique. The PartsNmore version is their part #39-1090 for this one top plate (hint: it was used from 1974 thru the last of the 750, not just the 1976-78 like the parts fiche shows) and the others are #39-1052, you need 6 of these, usually.
