I think I've been conditioned to expect things like this by prior Duc ownership so it doesn't give me conniptions. Ideally, yeah, it would be nice if everything was done correctly from the get go, but I am not going to sell the bike and get something I don't like as well (HP4, R1, April.., er, Busa) just because I think Ducati should have done some things better. I think it boils down to a personal decision point for each owner and I think this is true with most things you buy that have a high desirability factor like bikes. The amount of visceral reaction or love you have for the object when you first desire it is overwhelming...you must have it. Then you get it and reality settles in a bit and you realize it has a few warts. The point at which the warts outweigh the love is different for each person so I think we are seeing some people hit the "warted out" stage at this point and they should probably sell it. I think I have said it before in another thread, but it bears repeating. If mine starts giving me a ton of trouble and ends up sitting in the shop or on the stands more than it is being ridden mine will go the way of the dinosaur as well.
Another factor is the number of visible warts prior to purchase. I got my Pani later than a lot of folks since I was waiting for the colorless version (2013). Because of that, I was already aware of the heat issue, loosening bolts, darkening fluids, ejector cowl, etc. etc. so although these warts were annoying they weren't a surprise. I think the surprise warts really erode the love of the bike much faster than the ones I already had a heads up about.
