On the freeplay adjustment I had an old timer tell me... and I have forever did so since then... make the lever hold a dime against the control housing. That will give you the proper free play adjustment.
On the throw out bearing... I have had a bud on his AIH legend that kept having clutch adjustment issues... He would put it to spec... a few miles later... it would either get sloppy or tighter than ****.
pulled it apart... checked the ball ramp, the rod, and then the throw out bearing... found this..
Basically destroyed...
Picked up a new one... cheap part
Re installed, adjusted clutch rod and freeplay... good as new
