Hello! I am the new owner of a low mileage (12k) 83 GPz750A. I bought it from a kid for $100 and its partially dismantled but appears to be all there. I always wanted one of these bikes so Im excited to get it going. Does anyone know where to get gasket sets and that sort of thing for it? I read somewhere that the original gaskets all lead and someone makes another kind, graphite or carbon or the like, that dont leak. I also remember reading something about the shift return spring, accessed through the bottom of the motor after you take the pan off. This bike is all stock, but interested in improving the performance once its running good again. I also have some extra frame and fairing parts with it if anyone is interested. Scott-Glenwood, Iowa
