Strange sound when moving slow

[Ajwou]

Hi guys, just got home from a trip and noticed that my SV is making weird noise when going slow or setting off. It sounds like something is loose there, but I checked everything and all seems to be fine. I was wondering whether it could be the chain. This is my first bike so still learning new things and sounds;-). Any ideas what it could be?

What sort of SV do you have?

[Ajwou]

It's K8 N.

Is it a sort of knock just as you pull off in 1st gear? If so my mates does that too.

Sounds more like an inconstant sound of two non-metal parts bouncing. I'm taking it to a local garage tomorrow so hopefully they will find out what's wrong.
