Hey guys, as you probably know I have a 2001 Honda CBR1100XX. I have a noise that seems to be coming from the right side engine case. It happens at idle most noticeably. I hesitate to call it a knocking sound, and it's not exatly a chugging sound, but somewthere in between. It seems to go away when I rev up the engine. It's sort of an intermittent thing. My intial thought is that maybe the cam chain tensioner is worn/noisy, and the cam chain is slacking and tightening. I've replaced the CCT before with the X-11, but that was a couple years ago now... Anyone have any thoughts about my idea, or any ideas of your own? thanks.
