So I know there are a million threads about diagnosing engine noise. I've listened to quite a few of them, and they all sound much worse than my engine does. The videos that sound close to my bike are typically dismissed as the bike just being noisy.
03 600RR ~33500 miles. Yoshi slip-on, bmc filter, PC3, no other engine mods. CCT has been replaced once (by me) since I bought the bike, probably around 5000 miles ago. Definitely too soon for a stock CCT to go bad again, right? I also checked the valve clearances myself around 25k and they were all within spec at that time. I have no idea when they were checked last before that, and if they're potentially out of spec at my current mileage.
I began noticing the bike being louder while riding in traffic. The noise is present at idle and increases with the revs. I'm due for an oil change, but I've never heard this noise regardless of how recently the oil was changed. The level was at the lower line in the sight glass so I added a half quart, which had no effect.
I'm not riding until I figure it out, or at least know if I will be doing further damage.
The ticking noise is almost constantly audible, sounds kind of in the background. You can hear it slightly if you listen for it after each rev. It is very audible when the camera is next to the headers, at least I assume this is the same noise.
The youtube video seems to be slightly lower quality than the photobucket link below it. Try both if you're really nice and want to help me figure it out :D
