I recently bought a 1983 kawasaki gpz 550 for my first bike, but it needs new clutch plates and I can´t seem to find any. There´s a local place that can order them individually, but I don´t know enough to not get taken advantage of. He says I´ll need 7. Is this true? And if so, is that all I need? Any help and/or ideas would be greatly appreciated. Thanks
