Bad choice, LIthium grease will chew up the whole linkage system within weeks, just joking lol
You did pull the clutch cable OUT (Counterclock) right? Now make sure the lock nut is tight, not just finger thight. It's one of these rattles you'll spend weeks to find and will totally drive you nuts! Trust me!
There's this measurement adjustment for the clutch. Forgettaboutit, use common sense. Steering straight Pull the clutch lever just a tad and you should start feeling more tension afterwards. Now you should be able to feel this "gap" but at the same time it should be as small as possible.
If you don't feel this slack your cable is too tight therefore clutch might slip.
