Here's a shot from the manual.
I just bought a can of moly lube from the local auto parts store.
Rolled the shift lever at the case to the right, this will give you enough slack to get the cable end out of there, and enough slack to get the clutch handle out.
You will see there is a smear of grease on the top and bottom of the clutch handle. Just put a small smear of fresh lube there. Put some grease on the ball end of the clutch cable at the handle, then put it back together.
Pull the slack down, grease the ball end at the tranny case, connect the cable, and roll the pivot arm back to the left.
