I would do a basic clutch adjustment. Reference the owner's manual or factory service manual.

Does the clutch lever pull in ok without too much effort, or is it very stiff or not pull in much at all? It should be fairly light (see pic). If it's overly difficult to pull in it is possible someone has overtightened the clutch springs or there may be a problem with the cable routing. As a first step I would do as Martin advised and properly adjust the clutch using the instructions in the manual.

Another cause of the symptoms you describe can be the clutch plates sticking together from lack of use. Assuming the clutch lever pulls in ok, try this - with the engine off - put the bike in gear; pull the clutch lever in; and rock the bike forward and backward until the clutch plates break free from each other.

Agree with what others have said, however, if still these methods doesn't fix this disengagement problem....
Lean bike over and remove clutch cover .. The leaning over, is to avoid too much oil spillage.
Undo five spring retainers and gently lever clutch plates apart... they may be locked together so they will come out 4 or so at a time, clean them up, with usually oil you use in engine and reassemble. Careful not to loose 3/8" ball behind the mushroom type clutch pusher.

ok i cracked it open got all the plates out cleaned um up(were a it rusted) and put them all back together, the clutch now disengages but not 100%, i can run it in gear with clutch on and put on the rear break and it wont die, but when i let go of the brake the wheel starts spinning again.

and my clutch is kinda hard to pull not smooth at all

P.S i never saw a ball bearing when taking it all apart

Did you install a ball bearing? It really needs to be there. Ed

is the parts diagram for your clutch. Look for part #10. it's a 3/8" ball bearing.It goes between the long actuator rod and the interior clutch spring plate.

Without it, the push rod will spin with the turning of the clutch plates, making all kinds of strange noises and problems.

If you are running the bike off the ground, it's not unusual for the rear wheel to turn with the clutch in - it's not going to completely remove all of the friction. If nothing else, your going to get some drag from the oil spinning around amongst the plates. You should be able to stop the wheel turning with your hand, though, so that would be where I'd start looking.

If the ball bearing is missing, you will have the problems you are describing. There are probably other causes available as well, but a missing ball will definitely do this.

If you had rust inside your clutch, how is your cable?
Have you lubed it?
Cables are kind of cheap,
So why not try a new one.
