Got word back on my CB. The dealership confirmed hearing the noise, and had to call Honda. Honda was not overly concerned, and said that most CB1100s did that. I was not happy at all with that answer, but one of the shop's tech, who has a CB too, thought his did that as well. So he rode it to work so we could listen to it. And sure enough, within 4 to 5 minutes of warming up his bike, the rattling showed up, exact same noise as my bike. It also sounded to come from the exact same place under the bike. Honda says that the noise is created in the catalytic converter as it warms up. I was darn lucky that one of the employees had the exact same bike, same year, and to be able to hear the noise on his bike, otherwise I would never have believed Honda. The tech thought his was doing that rattle, but he had never heard it so clearly, as he had never let his bike warm up for that long before taking off. He was hearing it while stopped, with helmet on, and probably for not long since riding the bike gets it fully warm rather quickly. I believe I have read somewhere on the forum a similar case, from another rider, whose dealer started a brand new bike on the floor, and got the same result as his. Whatever the deal is with exhaust, the dealer was 100% confident that nothing was wrong with the engine. So I think I can put that one to rest. Picking it up my bike in the morning, and going to ride the heck out of it.
