hello. The clutch pedal has a regulation. But it is only distances of pedal routes. If the clutch already cuts high is fulfilling its useful life and there is nothing more to change it to avoid more expensive failures, you do not stop verifying the piston of the clutch piston for a possible failure in that system. Good luck and tell us.
The self -regulators cannot be regulated but they sell the piolas with mechanical regulation, of course that if it does not give you little of the clutch kit and it is better to change it
