Just make sure that the alternator rotor is properly tightened, loctited, dot peened, tab washer.............
I wonder if it is possible to temporarily hook up an oil pressure gauge to the sensor tapping on the crankcase as soon as the bike is ready to run. Record the pressure readings, oil spec, temperature etc. Repeat after 3,000 miles and compare. It might act as an early warning of problems without needing to strip the engine down.
