Clutch cable

Hey guys quick question. So I picked up another police kz 1995. Bike been sitting a lot. Looks much better. Clutch is super stiff. I removed the cable and cover on the bottom. Cable consists of 2 parts. Top part freely moves and bottom part does not move at all. Don't both of them have to move freely? Thank you

I don't know your model specifically, but every part of the clutch should move easily with little resistance all the way up to the clutch pushrod.
It's pretty easy to rub the clutch cable on the exhaust if its not secured to the frame correctly, this can melt it and make it drag.

Even when smooth without load, old clutch cables can drag badly when under load if the inner lining has degraded. If you don't know its history and the clutch is poor, it's probably worth replacing the cable, and cleaning and lubing the cam mechanism that presses the pushrod. Doing this is cheap and will rule out anything outside the bike - if you do this and still have problems you may need to investigate the clutch springs.

You can get uprated springs, and I've heard of people putting in completely different springs to incrase clamping pressure. I have 20% uprated springs in my KZ750 and even with that the clutch has less lever pressure than most other bikes I've ridden.

At least the casing in those cables were split in the middle, creating another weak link and corrosion source.   With a bike this old, I'd replace it with a new one, regardless as to whether the cable has parted. or stuck.    Cables are inexpensive

You can try lubricating the cable, but it will most likely need replacing.

After getting the cable sorted, the clutch may need adjustment. On some models you're supposed to turn the clutch release adjusting screw counterclockwise first until hard to turn, then clockwise 1/4 to 1/2 turn. It's kind of counterintuitive. Some manuals are ambiguous about the direction, even some Kawasaki service manuals. My 81 KZ650-CSR is counterclockwise first.
