I have an 09 zx6 and a couple weeks ago I noticed a slight rattle that sounded a lot like a bad throw out bearing in a car but this didn’t change when the clutch was engaged. It done it at lower rpm’s mainly. Then couple days ago I was leaving work and luckily before I pulled out on the road it sounded like something came apart and sounded like a marble was bounce around and it tried to lock back wheel down. Now when I try to start it it’s got a load high pitch grinding sound. A changed starter and looked at the clutch. Does anyone have any idea to what this can be?
