the clutch pedal resting height is adjustable via a bolt on the clutch pedal housing cage. the clutch bite point is adjustable via a screw nut at the end of the clutch cable.
adjust the bolt till the clutch pedal rest height is to your preference or to the oem spec, then you adjust the clutch bite point till it's between halfway and 3/4 down the clutch pedal stroke.
i prefer 3/4 down cos i just have to move my foot and not my entire leg to engage the clutch and feel certain that the clutch is fully engaged once released and secure.
i believe flat_outs original slipping clutch problem was prob caused by the clutch cable not being loosened enough or at all as the clutch plate wears down over time.
now if the cable has not been properly adjusted and that the clutch pedal/cable/swingarm/fork/thrust bearing rested in the same position..as the clutch plate wears it gets thinner and so receives less pressure from the pressure plate (which is being held back from the tension in the cable) causing clutch slip under high loads and the biting point to creep higher.
there's a narrow region between too much clutch cable tension, which quickly wears out the clutch system and wastes power, and too little cable tension, which doesn't allow the clutch to fully disengage, making gear selection difficult and damages the gearbox which is more £££ to replace.
i generally adjust the cable till it takes up slack and no more so that when the pedal is released, the clutch fork is just resting gently against the thrust bearing, and keep an eye on it monthly.
