I thought I pass this on.After installing a new belt I started the engine and had a terrible noise come from the front.Sounded like a bearing going out.Got the stethoscope and sure enough came from the alternator.Took the belt off and spun the alternator pulley it felt fine.Put belt back on started the bike same noise.It drove me nuts.I did everything by the book what could it be?So I went on the internet looking for help and here it was.IBMWR has it all written up under "Alternator Rattle".Something that doesn't happen to often.Could have taken me a long time to find.
