You are right about the original purpose of the valve. It should not do anything during clutch disengagement. But if you look at the valve itself, there is a tiny metal ball with a spring that is suppose to move when you press the clutch pedal. It still restricts the flow when pressing the pedal. After removing mine, I feel the clutch disengagement is much faster and smoother/lighter without that valve.I don't understand how removing the delay valve would have any impact at all on grinds while shifting. If I understand correctly, the purpose of the valve is to delay clutch engagement after the pedal is released. All of this should be occuring after the gear change has already happened. What I would expect from removing the valve, would be a more crisp clutch engagement and elimination of the slight slipping clutch feel when applying heavy throttle immediately after shifting.
And the difference in clutch engagement timing is even bigger of course.
