I've passed 30,000 miles on my 07 ZX6R now... I've had it into several shops and dealerships for the noise from the top end. It's sounded this way for 2 or 3 years now, like it's starving for oil. Just a metallic clackity-clack that's extremely loud on a cold start, and gets quieter as the engine warms up but is still present when warm, along with a persistent vibration from the engine.
5 days ago I walked outside to warm her up (my usual procedure I started *because* of the noise, despite living in FL), and I thumb the starter and nothing. Quiet as a whisper. Engine sounds healthier, doesn't make a single tick or clack despite being started at 38 degrees outside yesterday.
And the vibrations are virtually gone, all but what I'd consider "normal" are present. As if overnight, some dodgy mechanic had taken my engine apart and repaired it, leaving no signs of his handywork. I'm baffled. I've put new running gear on it but it's not that. The only "change" I made with the engine is having the dealership do my oil change (it was in for the valve cover recall) and they put on an OEM filter and Kawasaki Full Synthetic oil.
But I've always run ONLY full synthetic in it, usually with a K&N filter. Furthermore, the oil change was done several weeks ago and this just happened in the past 4 days.
I've been thinking CCT...do you think the CCT was stuck and finally adjusted correctly? Or that something broke, perhaps a chain guide, and is jamming the thing up tight? First thing I did was take it out and rev it over 10...not to the moon..but enough to say that I don't hear any sort of whine or anything that feels off.
Gift horse, or Trojan horse?
