If you have oiled the cable real good, and it still feels sticky, the cable may break soon. Had two of them break, right next to the clutch pivot. It never breaks in the garage, always far away, and always on a Sunday or holiday when the shops are closed. They break when you are holding in the clutch at a light waiting for cross traffic to clear, or when you are doing an important upshift or downshift. If it bothers you, change it now.
