You guys dont hear that clacking noise coming and going? It starts about 45 seconds lfet (as indicated on the Flickr player - it actually counts down, not up). And then when I rev it again at 20 seconds left, the sound is gone till the end of the video.

Why haven't I heard this before?! :)

Yeah I hear it, it just doesn't sound unusual, my C5 sounds much the same.
On the eighth day God created the C5, and it was better looking than anything on the planet.

Scooterbob or Kevin might have the definitive answer, but it sounds quite normal and fine to me.  

You should listen to an iron barrel motor to understand how much smoother these UCE's are.

In other words, I don't think you need to worry.  Somewhere I remember a slogan about RE's that jokingly said, "Loud Valves Save Lives."   :D

@SUB:

I have a G5 and I got used to my bike's sound.  My G5 has much less clacking / ticking sound.  There may be other reasons for low noise on my bike.  I use Star Tron fuel stabilizer and right now it has lighter engine oil 10W-40.  These two factors in addition to the fact that it has lot more miles may be responsible for reduced ticking sound on my G5 bike.  Oh, by the way the gunk accumulated in my engine head may act as sound barrier and muffle the sounds  :D.  

However, your C5 ticking sound has two peculiar features - it is a little louder and shriller than I ever had on my bike.  I have a link below of another person's C5 engine sound on youtube.  Listen at 0:28-0:29, the ticking sound with a shrill is noticable.  See if your bike matches with his C5.

That's a fact.  Yours sounds quite normal and good to my ears.  After a number of different makes and models over the years, I do know that the music changes as they break in and wear.  Different weight oils will certainly make a difference in the sound too.

OK - I bit on this ...... and there IS a bit of lifter racket going on there - but nothing that a UCE won't do. The fact that it IS quiet when you bring it off idle says to me that it ain't broke. If you revved it up and it got LOUDER, I'd then be concerned. Some causes - oil with too much viscosity, cold engine, or air entrained in the oil from being overfilled. ALL of these will make the lifters clatter a bit. If you are concerned, take it to your dealer - it HAS one of the best warranties on the Planet ..... Personally, I'd run it .... or, in the words of that ever-famous Ernest Angely:

"Place the afflicted part of your motor-sicle against the television screen, send a $75 dollar donation to ME and I'll pray, Pray, PRAY for the healing of the bike in the name of Cheezits and the Lard ..... "  ;D

Yeah - I paraphrased that just a little bit ......  ;)

@Sub- I heard the sound track;) and its just the auto -decomp playing about. I agree 100% with ScooterBob, its just the oil viscosity and cold engine. Little weight on the exhaust cam becomes sticky with cold and thick oil or sometimes the spring has more tension then required but settles down in due time and thats just normal.

If it makes it any better for you then I'll put a video of the de-comp making same noise on cold startups so you can relax and not worry too much about it.
