Even though your posts make no sense at all, I believe that you are genuinely trying. So, here goes. Let's get some basics out there first.
Clutch engaged--- you're riding across the dunes in a gear and your fingers are not touching the clutch lever
Clutch disengaged---You're sitting in the parking lot waiting on your buddies. Trans is in 1st gear, clutch lever pulled against the grip, engine running, bike not moving
There are basically only 3 SYMPTOMS of clutch problems.
Clutch will not disengage-- You pull the clutch lever to the bar, stomp the shifter into gear and the bike lurches and the engine dies
Clutch will not engage---You pull the clutch lever, shift into 1st, let the clutch out and the bike just sits there
Clutch works normally, but slips when you're really getting on the throttle
Now that we have those terms explained, start diagnosing.
You should have about 1/2" of free play in the clutch lever on the bars. This is the distance that the lever pulls easily. The actual amount isn't critical as long as it's a close. 1/4" to 1" will still work. If you have 3" of free play, the clutch will not disengage completely.
Assuming you have some amount of free play, now go to the clutch actuator(lever on top of the case). Push the actuator towards the right side of the bike. It should push easy for a small amount. When it stops with just light pressure, the pointer on the arm should line up with the pointer on the top of the case. If it doesn't, then you have things wrong in the clutch and the clutch cover needs to come off. It could be that someone adjusted the pressure plate adjustment screw wrong, a worn out clutch, or other problems. All clutch problems can be fixed without splitting the cases EXCEPT a severely welded clutch ball that is stuck inside the trans shaft.
If the pointers line up properly, check your freeplay at the clutch lever on the bars. If it was fine before and now all of a sudden, you have way too much freeplay, the clutch cable stretched. Probably broke most of the strands, and the few remaining strands stretched.
Now, let us know what you find based on this information.
