The ratio of pedal-to-bearing throw is ridiculously high, especially for such a small engine. For the stock system, what may feel like reasonable disengagement is actually marginal.
@Tcoat will attest to my clutch setup. I have my pedal lowered but I also have a corresponding mod to increase the throw at the clutch fork. The two changes cancel each other out to maintain effective disengagement.

When your clutch pedal is fully released, where does it sit relative to the brake pedal? If clutch and brake pedals are about even, the PO lowered it in vain attempt to gain some feel.

Also, in my sig is a a link to the manuals graciously served by a fellow owner. In there are instructions to adjust the clutch pedal to factory spec. Try that before you wear out your new transmission.
That's an interesting theory. Could you go into a bit more detail about how the distance after disengagement makes a difference? Because my un-informed understanding is if the primary doesnt move in neutral then you are good. But maybe there's something that I don't know, or perhaps it just plays a role in what happens in the course of changing gears? When I get home I can try letting it go slightly and repeat the test to see if the primary is spinning.

Just off the top of my head I feel like the clutch and the brake pedal are dead even when it's just sitting, and I can bottom the clutch pedal against the floor (at least that's what it feels like, never got down on my hands and knees to check) and that's what I'm considering the fully disengaged position.

But that would make me very happy if adjusting the clutch would fix this because that is kind of what I had originally thought as well. Way too weird for the gears to be this cranky across the board. But It's been to three dealerships and none of them said a word about it after driving it on the interstate no less, so I guess I naively was considering that data point as well.
