When I was using the old L6, I just used to put it on, leaving say a 3-5mm gap between it and the body so free to move, twisted it then let it spring back and screwed down in that position.
I don't use the iscv on mine(K3) even though I have manual control of the idle speed at all times, not found a problem, though tps set up is only press the accelerator and release for me, if disturbed to recalibrate it.
