If there is enough of the old sprocket cover gasket left then shouldnt need replacing... Is the chain not suffering from a tight spot somewhere around its length causing the excessive bounce?... If you mean the front sprocket nut? then i dont believe the dealer will replace it as a recall.. The upgrade nut is however not an expensive replacement from the dealer..
Better to have it and not need it, than to need it and not have it..
