    About the only thing I can think of is "Cam Slap" assuming that the valve shims are all within spec.

      Cam walk. Does it go away above idle?

        Right, looks like I botched that term.

          My 550 does a similar noise. Maybe not as loud but its the same ticking which comes and goes ever 1-2 seconds. I think its a "normal" feature of these motors.

            No it doesn't go away above idle.

              My 450 was starting to do that before I traded it for another bike, it would last about a minute or two then go away. It's a matter of wear and things tightening up after the metal warms up. Even going a minute or two with the noise I'd still ride it anywhere, from what I've read it isn't too daunting a task to correct it. I've not actually done the work and will leave that part to someone else but as mentioned, if it's only a minute or two you're safe for the time being.

                Yes, Sounds like cam walk. You can be sure of it if your bike has the plastic seals at cam ends- turn them around (flange side "inward") next time you have the camcover off. It'll stop. This is a temporary fix but at least you'll know.

                Actually, in the noisier instances it doesn't go away. You just can't hear it easily at higher rpm.
