This adapter allows the use of a GPZ1100 or 1000J model cylinder head on the earlier KZ900 / 1000 lower end. It maintains the roller style cam chain. This is the only modification necessary to install the late big valve head on the early motor. Use with OEM KZ sprocket or the high-performance version at the right.
