Technically, I would have glue a clear cover over the clutch oil filler cap. Place camera at the hole, watch the clutch grow so you lose that lever. Guess WOT? Happens with cable clutch levers too. I would hammer some old style 750cc size engine say.
I'm going, what the hell happened to my lever? Mind you, I'm still shifting gears using the lever. Why don't we walk the X to Y and eliminate one. I don't know if you got a visual ever trying to work alone needing more hands, butt if you got that picture in your head...
... Start with X:
1. We have a push rod that is so long.
2. We have to push that rod far enough away from all the plates so there is a gap between frictions and steels.
3. We have been pushing bubbles to cause the hydraulic lock to happen farther down the lever throw.
4. We have the lever more in the middle before the rod moves. That means; hard to find N and/or creep at a light w/clutch in.
5. We have a short throw if we cannot remove all that air... Period.
6. We have our pack correct, we have a lever farther out and loads sooner, because the piston has less to compress in the caliper being deeper set in the caliper housing.
7. We have so much 'caliper piston distance' designed in as is the 'length of the rod,' as is the 'stroke distance of the master's volume.'
8. We have our 3 amigos all designed to have a certain distance to break plate = NO BUBBLES!
9. We have concluded that if the rod did not collapse; the pack did not 'wear past the serviceable limit'; the hydraulic system is as designed for the other two items stated...
10. ... We have concluded, it is not X.
... End with Y:
1. Why does the clutch grow and then show no joy at the lever?
2. Why I have no clue but to guess with you.
3. Why I'll bend over and take a crack at it.
4. Why then do we have both clutch growth no matter it cable or liquid levers?
5. Why that is the 64K Q. If X is fine on a cold or warm engine, we hammer some clutch plate and did we slip it?
6. Why I don't know that question. I would think if you pull lever each time, it has to slip if the wheel slowed but the engine did not so much.
7. Why bring that up? Because we are at the Y and Z means growth. We want to know why that lever when 1/2 pull when hot.
8. Why here is my guess. See those blue spots on the steels?
9. Why I think those stick out where they are the high spot or have some warp going on the slip buy you can't feel it so much as it is still holding but say the pressure plate is pushed out from it.
10. Why I can't bring X into that factor because the rod is permanently fixed as are the other amigos.
11. Why whom be left but something that can grow and if that pressure plate is pushed out, would that be the same as saying you have the lever pulled about there?
12. Why you can still pull it to the grip and it finally breaks because the distance was not that much.
13. Why not the basket grow out with that band around it.
14. Why would you think it would more grow where? In? Then if the plates moved the other way, would that not push that lever more out to where it would break the plates right there in the stock setting?
15. Why then would not Y be that growth out, pushing the pressure plate? Thus the HD spring change at the pressure plate?
16. Why I think we can go back to our first step where the KAK first bled the amigos? Air apparent?
