Fwiw i have a speedo healer fitted.
are you saying when you swapped to the 750 you used the same 15/48 sprocket setup you had on the 600?
or are you saying you now have the stock 750 final drive ratio?
I have heard the transmission ratios for the 750 are different, a 2001 600 has a taller ratio than a 98 750, it appears the 01 600 compensates the internal ratio in the final drive, a taller output with a lower final drive
someone correct me if I'm wrong as I dunno what the correct transmission ratios for a 96-00 600 is..
if you went from a stock 750 16/44 setup and went to a 15/48 you have increased torque by 14.1% and decreased speed by 14.1%
if you used the stock final drive ratios on the 750 I don't think you are very far off the stock 600 final drive as the use of a smaller rear sprocket is compensated by a shorter primary output, however I would assume the 750 does have a slight higher overall final drive gear ratio in terms of wheel revolution simply by considering the 750 has a slightly higher top end speed and red line of 1000rpms less
this is all speculation I don't really know the reality as I don't have a 750, the 750 may have a higher top end speed because it will actually reach red line i 6th gear as my 600 will not, therefore actual speed is like 145 TOPS on my 600
