While you have the side cover off, see if you can loosen the locking nut on the clutch adjuster. They can be stubborn. Once it's away from the plastic part you can apply a little heat. Then clean it all up and pack the plastic part with grease and use blue locktite on the two screws holding it all on. And anti-sieze on the lock nut. If the plastic part has cracks it can make the clutch lever not so effective. Mine didn't but I've heard of some that did.
