The bike has been in the shop for 4 days not including Sunday. Today, Wednesday, the dealer confirmed the rattling, and called Honda, as they can't figure out what it is. The motor doesn't seem to be the issue, and it could be in the exhaust, as the noise shows up after a certain amount of warming up, and disappears at full warm up. They think the problem shows up as something metallic is getting hot. They'll be on the phone again tomorrow with more directives from Honda, and how to proceed. I actually would love it if it was something in the exhaust. That would be an easy fix. However I am still feeling good about dumping that 10W40 out and replacing it with the 10W30. I like to stick to the owner's manual. It also allowed me to flush completely the 10W40/brake-in oil mix that was in there, as a lot of brake-in oil was probably left in the oil cooler.
