ok i tried the spring to return the fork, spring is not strong enough to pull it back, tried many springs , i just cant see why it needs so much pressure to pull the fork back, my bearing is always running on the pp. my only other option is to remove the internal spring.

now 1 more question, i have bled the dammm thing at least 50 times, ill even pull the fork all the way back and then tighten up the bleed screw, and all is fine, slave does not push out at all, ( it stays bottomed out) press the clutch and it goes right back to where it was before, WHAT GIVES???

There must be something binding. When I adjust my clutch (pic below), both the plunger coming out of the slave, and the fork itself, will easily push back towards the slave with nothing but light finger pressure. However, I do remember changing out clutch fork return springs decades ago that were very, very strong. So strong in fact that you were afraid of trying to pull them with vise grips because, if they slipped, they could do some damage to you. Instead, we would bend the springs open and put coins between each round of the spring, maybe a dozen or so, and that would spread the spring out so you could easily put it on. Then you would just pull the coins out one by one. I haven't thought of that in a good 30+ years.

When you bleed it, you must force the plunger BACK INTO the sleeve before you attempt the next bleed. Connect it to the shift fork so the pressure of the fork pushes it back into bottom of the sleeve.
