With great reluctance, I am going to join the 'Just ride it, you've got a warranty' brigade. The most important thing is that it is recorded with BMW so in the event of a very big bang, they can't say you didn't tell them. Issues like this ruin your enjoyment of the bike and play on your mind, living rent free in your head (Don't ask me how I know). It's worse because you are an engineer. My 1250 makes all types of scary noises that I notice when I haven't got the earplugs in and my riding buddy's new 1300........takes it to another level!! Take care buddy.
