I ride my CBF 1000-A6 (MKI) all year long. No rain, shine or storm has kept me out of the saddle and I've never really felt any need for anything other than the stock cowls, screen and seat, they work just fine for me. I've done some extreme riding on it too including 1,000 milers in 24 hours, 1,500 and 2,500 miler weekends etc. The CBF is a great no frills sport tourer, you'll love it.
I wouldn't worry about the stator, too many naysayers with little or no knowledge of stators, regulator/rectifiers and charging systems have written so much irrational hype about them its difficult to sort the fact from the fiction. Many perfectly serviceable stators and regulator/rectifiers have been replaced without any proper or thorough diagnosis.
