Picked up this 2012 r1 with 2700 miles about 2 months ago. Put a little over 2k miles on it. Did the oil change when I first got it using full synthetic valvoline 10w40, and after a hard 2k miles I switched to yamalube 10w40. After that, I noticed this "ticking" like something is rattling around inside the bike. I've had a few mechanics tell me it could be valves, but how would a valve be out of spec at 5k miles? This shit is driving me crazy. I changed the CCT to a manual one yet it still makes the noise. Tightened it to the point it would do the hollow sound on start up, still would make the ticking.
