Havent been around for a while,
Again, im not familiar with the clutch setups on these as the 3 i have aer all auto. However, typically hydraulic clutches wont have an adjustable friction point. Try bleeding the clutch system first and replace the fluid.
You can adjust the pivot to push-rod ratio on the pedal and this will increase or decrease the throw. This usually requires custom modifications.
This is a customized clutch retrofit i did on my falcon. Clutch pivot (top of picture) and pushrod pivot (bottom of picture) notice the second mounting hole above the pushrod pivot. if i were to move the pushrod to this point my pedel throw would reduce and as a result the friction point would be closer towards the end of travel.
the other method is to change the bore size of either your master or slave actuating cylinders. If the cylinders are both 3/4" bore then 1" movement on the master will produce 1" movement on the slave. the ratio is inverse. if the master was 1/2" bore and the slave a 1" bore, then, pushing 1" on the master would be 1/2" in the slave.
