The ball bearing is a blank for the oil feeds. You are supposed to loop one of the 2T feed pipes between the oil injector unions on the carb bodies, and press the ball bearing into the tube to prevent any bleeding across the carbs.
Use the other 2T pipe to loop the two outlets on the oil pump to blank it off, or remove the pump and fit the HRC blank plugs/plate to the casing.
Of course, if you keep the injector pump, keep the ball bearing in the bag!
