1983 Kawasaki Gpz 750 starter clutch repair /replacement? It rattles but does not turn the engine, so I figure that at minimum , it needs the roller/spring kit and maximum a new plate that they seat in as well ( the plate can crack and will then never work). Problem is: I have never done one on this motor and do not know how to proceed. I see that the earlier KZ engine (starter motor on front of engine ) requires sump off as well as side covers. Any experts out there?--
