I have a 2006 zx6r with 19k miles on the clock. Ive noticed over the last 800 miles or so there's a noise up in the top end. It sounds like ticking or clacking sound and speeds up with the throttle. Im assuming its the valves and they've loosened up, yet I know commonly they tighten up as the miles go up so Im just wondering if the noise is still most likely the valves. Also, if its important the noise was faint at first then after a couple hundred miles it got louder and so on until its at where it is now. Any insight into this is much appreciated..
