Clutch biting point issue, worn clutch basket?

[b1k3rdude]

The fact you can't get enough free play at the bar is an indication something is wrong.  You need to check the operation of the cable, all the adjusters and the clutch release mechanism from one end to the other.  Slacken off the lever adjuster and see if the cable is moving freely, then check the arm pivot for movement/operation.  It's possible the cable is dry/damaged/out of adjustment and now over stretched and in need of replacement.

I can get free-play just fine, the cable is fairly new with not that many miles and has no stiffness but will check anyway.

Screw the cable adjuster at the lever back all the way allowing plenty of slack and adjust it at the engine end

I will do this to move the arm, to see if it gets more a swing/pivot. But to be honest how much realistically does this gain?
