I've never owned anything later than a 2001 ST, but on the these bikes the brake and clutch lever have a large grub screw near the pivot. It looks for all the world as if you can use this to adjust the lever span but this is a mistake, because if you adjust it too far the master cylinder piston doesn't return far enough to let brake fluid return and the brakes effectively 'pump up' until they lock.
Since, somebody mentioned 'grub screw' earlier on in this thread could it be a similar problem?
I know the 749/999 have a different master cylinder and I've never really bothered to look that closely at them so I could be talking rubbish
