a 630 chain & if it doesn't fit (rollers too big), then someone probably did a 530 conversion. You can measure the pitch of the rivets
on your old chain. pitch = distance between rivets. 630 rivets are 3/4" apart center-to-center. 530 rivets are 5/8" apart.
note: it's usually recommended to replace the chain & sprockets as a set.
Z1Enterprises.com may have what you need. I get most of my maintenance stuff from them. see ad at top left.

Regarding the chain -
You really need to replace the chain and both sprockets as a set. Sprockets wear, and when they wear the geometry of the teeth changes. This change, even though it may appear minor will cause a new chain to wear out very quickly because the spacing of the rollers is not a good match for the spacing of the teeth on the sprockets. Replace all 3 pieces as a set or you are throwing money away on the chain.
According to everything I read the KZ750-H3 and KZ750-H4 use the same chain and sprockets. The front sprocket has 13 teeth, the rear sprocket has 32 teeth, and the chain is size 630 with 84 links. Below are links that show this info. Ed

The stock ratio is 2.462 (32/13). The closest 530 setup to that ratio is a 16T Fr & 39T Rr (39/16 = 2.4375).
To lower the highway rpms, you can probably go with a 38T Rr (38/16 = 2.375).
note: i believe a 530 16T is slightly larger in diameter than a 630 13T, but I think it will fit.

Martin already detailed what sprockets and chain to get
38 tooth rear is fine... www.z1enterprises.com/530-jtr488-series-38t-rr-sprocket.html

I know it's not a 750 but here it is any way, I wanted to stay as close to stock with the final drive ratio as possible.
The 530 equivalent chain conversion is as follows;
(1) Counter shaft sprocket 17T p/n BAJTF513-17
(1) Rear Sprocket 38T p/n BAJTR488-38
(1) 530 Chain 114 Link p/n LA530XSOZ1-114
Original Final Drive ratio = 2.20 (4000 rpm) - 15/33
Conversion Final Drive Ratio = 2.24 (4064 rpm) - 17/38
Thank you,
Norton
The new set up with added split master link was around 166.00 before shipping
The last time I bought a 530 setup was 50,000 miles ago they sold me this set up and the Final Drive Ratio was very similar sounding
18 front
40 rear
110 link
I hope the new set up works as well as the last

We hardly ever get caught in the rain and the bikes are garage kept in the summer and are in the house for the winter months.
I guess 50 K is all I can expect out of these new chains
You can't tell from the out side because I kept up with the waxing , doing it while the chain was warm just after a ride.
but the inside was rusting out as can be seen on the front sprocket.
The chain never really stretched out much after the initial setting.
