Use star washers with INTERNAL teeth. The external tooth type will allow oil to wick along the threads in the crankshaft hub and contaminate the clutch facings. A drop of blue Loctite on the threads will also help prevent oil leaks since the front of the threads are exposed to oil splash from the crankcase.
