Weird knocking sound when disengaged clutch?

[Callmedaddy101]

I recently bought a CBR150R (2012 model). I noticed that the bike has this weird like knocking sound when the clutch is fully disengaged. So when I'm in neutral, and I fully let go the clutch it has like a inconsistent knocking sound that weirdly gets louder when you're on a downslope angle. I checked with a mechanic at wingyap he said most likely is the clutch housing or something loose. As of other issues, the bike vibrates A LOT when throttling. Considering selling the bike off at the price I bought it at. Wanted to get opinions from you guys before I spend the money to get it checked and replaced or sold away. Do help thank you in advance!!

there's a few things that might have happened.

1) Valve

2) clutch housing like your mech mentioned

Usually knocking sound is not a good sign.. so even your next buyer will definitely ask you what sound is that and etc.
