If the lever is tight then in may not be releasing the clutch all the way, I would try this before buying a clutch. While you have it apart inspect the clutch and see how it looks. I always screw the adjuster on the lever all the in before i adjust it at the clutch so you will have all the adjustment you need at the lever. You turn it counter clockwise, the way i do it is loosen it, then screw it back in till it bottoms out, then back it off about a half a turn.
