When using the stock bike slave cylinder with a Girling type master cylinder (normally Ø.625″), it is possible to push the pedal too far, causing damage to the clutch.
Fitting a pedal stop (applies to a cable operated clutch too) is an obvious solution and ascertaining where the stop should be is fairly simple.
Adjusting the pedal stop should be carried out with the rear of the buggy securely raised on stands. While idling in first gear, lightly drag the brakes and push the clutch in slowly. The point where the wheels stop rotating is the position where the clutch pedal stop should be – plus a quarter turn. Much further and damage could occur.
