Got a '80 Kz440 that won't shift. No pressure on clutch lever. I replaced clutch cable thinking that would fix it. I had pressure on the clutch lever, put everything back together then I went to shift into neutral and I hear a "pop" sound, and now back to square one no pressure on the lever. What gives? I just changed the clutch actuator, no change. When I press on the clutch lever there is not enough pressure to move the actuator of the lever back. Is the clutch return spring supposed to be really tight (mine seems a little warped and loose)?Another thing, When the clutch cover is off with the actuator, everthing is fine with the lever having pressure. When I tighten the cover on the bike, the lever will not press down all the way or return.
