Hello good sirs. I am in need of expert advice once again. This issue literally started over night. It was not gradual at all. One day it was fine, the next day; I took my bike out and could no longer pull the clutch lever with one finger. I had to grab it with my entire hand and pull it all the way in to release gears for shifting. Clutch did not seem to be slipping at all. Still shifted fine up and down as long as I pulled the lever all the way in. Pulled strong in all gears. I was diagnosing this when I found a mouse nest built on top of my engine. I removed the clutch cable and it seemed frozen stiff. I couldn't pull it back and forth manually. I thought that was all it was and ordered a new one while I worked on repairing chewed up stator wires. New clutch cable came in, installed..same problem. It seems the issue is down at the lower clutch arm..pictured below. I cannot depress it manually by hand at all. I have to butt a piece of wood against it and press extremely hard to get it to move inward. I tried the clutch adjustment in the manual with the clutch adjusting screw to no avail. Any ideas?
