I had a 2004 EV hydro motor with a clutch lever that felt firm and positive, like any Japanese bike I've owned. I have also had 2 - 2001 Jackals and now an '02 California Stone with clutch levers that feel "soft"-- almost like the cable is stretching or coming unraveled when the clutch is being disengaged-- but the cables are not stretching, and the engagement point does not change.
Is it possible I am feeling the difference between a single and dual plate clutch?
