what, me worry?
(this is my second half of the post of this problem) so i used my trusty impact that i was told about to get all the damn parts off.... the clutch has been holding open, long story short i over adjusted the clutch lever and when i was at a light i heard a pop and the clutch got stuck open. pulled everything apart. the armature seems to be arcing fine, but the clutch lifter arm (pictured) doesnt move in or just spins freely.... i can only assume it moves in to engage the clutch. yeah its not moving in, ill try putting some muscle into it. any ideas on what it could be next? ...i take it im going to have to take the opposite side cover off, and inspect the clutch spring and the armature from the other side...

Lets see if I can explain how this works without using my hands. The clutch cable pulls up on the arm in the first picture, rotating it through an arc. That arm is set in a threaded hole so that as it rotates, it should also move in and out. That little ball in the hole pushes on the clutch pushrod (bottom picture). The clutch pushrod pushes on the clutch, separating the plates, disengaging it. When everything is installed and working correctly, that arm is supposed to convert the up and down motion of the clutch cable end into left to right motion of the clutch pushrod. The cable pulls up, the arm rotates up, the ball gets pushed to the right, the pushrod gets pushed to the right, the clutch cover is pushed to the right and the plates seperate.

If the arm is not moving in and out as you rotate it, I would take that bit apart and clean it to make sure nothing is broken.

I don't think you will be able to operate the clutch by pushing on the pushrod with your hand. You need the mechanical advantage of the mechanism in the sprocket cover.

thats exactly how i imagined it worked. now.. the funny part is though that when its all together the cable cant contract or move out of the sleeve... something is binding or is broken. ill tear apart the other side in a day or two and go over everything... i have the bad feeling this is going to be alot of work
 
Before you drain the oil and mess around with the clutch itself, I would take that part in the first pic apart, clean it and inspect. Try to get it working properly. Most likely, something in there is wrong or not adjusted properly. make sure you don't lose that ball in there.

Also, check you clutch cable.
 
ok, cleaned the armature and re packed the bearing with grease. moves much more fluidly. i put the cover back on and adjust from there, attach the lever and its still hard as a rock, and not moving. So, let me make sure I am correct, that the Clutch lifter rod SHOULD be pushing back out after the clutch is released. the clutch has been still stuck open, regardless of the cover being on. im looking through my clymers and honda shop manual, but i dont think I find a spring or diagram showing that there is one. what mechanism or spring pushes the lifter rod back in to position?
 
ok. well i found the diagram for the clutch in the PDF that Noel put up. ill be working on it more tomorrow. any suggestions on what should be looking for?
 
Umm dude, i had the same thing happen to me after taking my motorcycle test... all i did was loosen the 12 mm bolt and screw the flathead to the right untill it kinda poped back in, then tightened it back to where is starts to give resistence, and retightened the 12mm bolt. Are you making this harder then it is or did i missread the OP?

......i might be.
i think ill try your method tomorrow... theres the possibility that its not making contact with the clutch lifter arm.... i never thought of that... ill update this tomorrow after i tinker with it. thanks for the idea star.
