When i undid mine on the new 4k (when it was in the shed) I put a piece of flat bar on the flywheel and turned the engine over untill the clutch bolts locked against the flat bar.
and to remove the pulley, i used two bolts through the tapped holes in the balancer. alternate between the two every 1 to 2 turns of the bolt. just make sure you have something behind the pully for the bolts to press against.
