These bikes make more noise than some, even when there is no issue. Easy things to check will be the power valve, which can rattle if the actuator arm is making contact with the hole in the cylinder/case, chain slap, and the expansion chamber at the exhaust spigot or one of the mounts. Could also be pipe bang
Post a video with audio if you can.
Can you hear the noise with the bike in and out of gear? Does it go away when you pull the clutch lever in? Does it change with RPM?
