hello, I have a LS 650 - 92 year, I have a problem with the valves knocking, after adjustment it continues. After disassembly and inspection, I found a radial play on the sprocket of the timing chain, is this normal or is it a problem?

Hello, after an incompetent intervention when changing the clutch and timing chain, it started to knock very loudly somewhere in the motor, I adjusted the valves according to the repair manual, but the problem remained, in between it temporarily started to oil the cylinder and the head and I had to disassemble them and this it made an impression on me. I can make a video of the chain and knock after I put them back together if the problem persists. Thank you for the information.
