Good, you noticed. I see maybe someone tried it on that pulley pictured? ( its missing a chip on the top right). thats why your suppose to attach the puller to the Inner lip... Most good UDP are made from solid billet blanks, the stock one is cast. As a result the new pulleys are pretty damn close to balanced. I had my crank balanced with the UDP, hardly noticeable, they did shave a bit but you cant even tell anymore where they did.
