As for the noise being normal, once again we are dealing with the MoCo calling stuff "normal" just because the parts fit within their looser and looser tolerances. If it was truly normal, they should all exhibit the same noise. They don't. The question really should be, is the noise "acceptable" to consumers? Companies that actually give a chit about customer's would determine from all the complaints that this isn't acceptable and attempt to improve the situation. Harley, however, just trots out the ubiquitous "it's normal" statement and expects the customer's to live with it. Perhaps a good set of isolating ear plugs should be standard equipment with the purchase of a late model Harley.
In all seriousness, some of the stuff folks complain about in terms of noises really isn't worth worrying about, even though Harley could fix them if they really cared to do so. The trick, in my opinion, is in getting them to honestly evaluate each situation to determine if it's truly OK, versus the dealers just blowing everyone off because Harley puts out all these "normal" bulletins. There have been a lot of situations where dealers have told people their complaint was baseless and the situation was "normal", only to be proved wrong when it failed completely once the warranty had expired or when they were out on a trip somewhere. When a company is always playing the "normal" card to avoid fixing stuff, it is a little difficult to keep believing them.
