I am trying to figure out a problem with the clutch on my bike. (xl350k1) the clutch is not engaging when I let go of the clutch lever. I have ruled out the plates and springs (changed friction plates and measured springs) and cable tension seems not to be an issue. I am thinking it may have something to do with the internal clutch lever on the left side crank case cover. i can usually kick or pull this back into place, and the bike will go into gear. Anything I should keep an eye out for when I take off the crank case cover? Any help would be greatly appreciated.
