2016 Honda CB1100EX Abnormal engine noise

Hi Jason, your engine sound normal to me. The bottom rattling noise is cause by the balancer shaft, which to me sound ok. You could adjust to reduce it more but it will wear out faster if over tighten.

Thank you, then I'll adjust! Do you have a Facebook account?

Some times using 10W40 oil will do that. If you switch back to 10W30 the noise may go away.
