Definitely something wrong. That noise is not normal. Is it coming from inside the clutch cover? Sounds like something hitting the inside of the case as it spins. Are those scrape marks on the right side frame? Could the bike have been dropped, previous owner replaced the clutch cover, but something not right inside?

If it does sound like coming from behind the clutch cover, lean the the bike on something tilted as far over left as you can (so oil won’t leak) and remove the cover to see how it looks inside.

Engine noises are hard to pinpoint where they’re coming from as sound travels through other parts. An old trick is to use a longer standard screwdriver, put the handle in your ear and touch the blade to the case, just like a stethoscope (if you don’t have the real thing!)

Sounds like the starter gear didn’t dis-engage

yes , i think it comes from right part of engine , as you write, it's hard to find right location , but it looks it's right side . yes , i buy this bike from copart , after damage , and clutch cover was replaced by previous owner , but before this time bike was starting well . trouble is starting from 3 days ago .

Don't know, I'm no professional, just a monkey who will get out the wrenches and start cursing. It just sounds like the gear isn't disengaging fully

Good plan, also does the noise change with revs? In gear? Wack the starter with a dead blow hammer or block of wood, see if it stops. Hard to diagnose from a vid
