Actually, that is the stock tire size for a 1981 KZ650-H1 (CSR).

Ok what do you see as the usable powerband of Frankie? Where is the lower end of the torque? You don't want to gear so tall that you can get across the intersection without smoking the tire. Also it is always a compromise. Lose accel, and gain speed/ cruising RPM lowers. Fuel mileage would increase, if a good selection is made. One thing about front sprockets is they are cheap enough to try one out. Then if it is to much your only out like $20. Could even be resold for near what it cost if you don't ride it long.

Since the tire and the 13/33 sprockets are stock size I wonder if there are some gear ratio differences within the 750 transmission that account for the high rpm at 60 mph? Or it could be the tach is not accurate, you may want to check it with a dwell meter tach or some other electronic tach. The speedo may not be accurate, but they generally read higher than actual, not lower. The other possibility is the clutch could be slipping a little. Ed

I have a '78 KZ650sr/738cc,pipe,vm24s and pods with 16/38 sprockets(530).
It's a little weak off the line and top end is not improved that much.
13/33(630) = 2.538/1
16/40(530) = 2.5/1(most stock 650's)
16/38(530) = 2.375(tallest rear commonly available)
530 - 13 to 17,38 to 42 if I remember right
