Never owning a rzr im not sure if this is just a normal sound or if i have something going on

generally between 40/50% up to about 80% throttle i have this rattle type sound sounds to me its coming down below my seat belts however its hard to pinpoint exactly. I cant get it to really doing it by free revving only when riding

I thought maybe it was the shield on the exhaust pipe but that seems to be solid, goes away at WOT and just crusing at a consistent speed its not there either

The sound almost resembles a loose chain type sound, but i dont think there are any chains on this application just drive belt? Any ideas or suggestions would be great

Thanks in advance
