Rebuilding Motor

A couple of suggestions. First, I would replace the (4) "figure 8" gaskets under the valve cover and re-evaluate the oil usage. If these gaskets are in bad shape, you are sucking oil out from under the valve cover. You would be using oil but not burning it. Second, the valve stem seals on a 12-13 YO bike are age hardened and not very effective. Over the Winter, pull the head and have the valve job touched up and the valve stem seals replaced. Rarely is oil usage in these motors from ring/piston/cylinder wear.
