Clutch stays down. Slowly will take of with clutch fully pressed. Does not slip.dont understand

It sounds as though the clutch pressure plate has become weak.

When you press the clutch pedal the release/throwout bearing presses against the centre of the clutch pressure plate. This causes the metal 'fingers' -the springs- on the pressure plate to flex and release pressure on the driven plate - momentarily disconnecting the drive from engine to gearbox.

The link below is of generic clutch images
how clutch works Google Search

A weak pressure plate isn't fully releasing the driven plate. If you're going to do any replacing of parts - a clutch should be replaced in 3 units: Pressure plate, driven plate and release/throwout bearing.

1989 Kawasaki ZX 10 clutch lever master cylinder jams up

...??.. the bore that the plunger rides in may be worn to the point of allowing it to bind... its a wear related thing..your bike/master cylinder IS 28 YEARS old...
Do a full master cylinder rebuild..if it does not fix it.. think about a NEW master cylinder..(a used one is NOT ok)..

take out the master roll look under the green plate you will see a white plasic knob, at the moment it is to the back of the machine that is the cutter unit, very carefully move it to the front of the machine until it wont move anymore. dont forget to switch off the machine, refit the master roll the problem should be resolved

Text message aint functioning!

You can try the master clear but be cautious because it will erase all ringtones, contacts, everything in your memory that was not standard. Usually the master clear works though.
