so this morning i go to get on my bike and I notice the clutch won't disengage. I took off the sprocket cover and clutch lever arm, and it seems like the pin doesn't push in anymore. its just solid. I should be able to push this part fairly easily by hand, shouldn't I. It was running perfectly lately. Its weird. I know my pads were shot, but don't think that caused my freezing problem. I have the pin and the ball bearing still. any help appreciated.
