The movement means nothing without a reference point.
Is cable connected?
Could be worn plates, arm positioned wrong on splines, not adjusted correctly (usual cause) clutch basket loose on shaft, etc, etc.
It may also be the one with a pressure plate adjuster inside the cover (which kinda sucked when you had to drain coolant to adjust clutch
) I worked in Suzuki dealers when these were new, just forgot which one it is exactly
