Frankym,

Unfortunately, there's no such thing as a free (clutch) lunch... If you reduce the master cylinder diameter or increase the slave cylinder diameter, you're going to lose throw at the clutch fingers. And probably end up with a problem.

Since this kind of leg pressure is not typical of
a Centerforce clutch, I suspect that there's something binding or creating interference in the clutch or linkage itself - and that's where I'd look first - waay before I started changing hydraulic parts.
