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!)

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

how can i check it ? maybe start bike from second gear by rolling ? if it does not make this noise , that's it ???
Yes, bump roll it in second or third and see if it does it then. Like someone else suggested pull clutch lever in and see if it still does it, that will eliminate a couple of things.

i start engine with rolling in second gear , same noise , and also when motorcycle is in gear .

tomorrow i tried to take off starter cover , and that's what i see there ...

i think it's condensat from cold weather , and i ride everyday not as far on work , just about 2-3 miles . anyway i think first i want to try wash engine with some special fluid , and then change filter and oil . i think that oil quality is bad , so oil pump can't work properly , and need time to pump oil in system . what do you think about it ??? because , after few seconds on start , there is no noise at all .

There can be two reasons for this :
This may happen due to condensation in the engine. Primarily the reason for condensation is either the change in weather or you are not riding your bike enough. If you ride very short trips then your bike engine will not get enough time to burn off the water vapours. These vapours over the time will create a milky sludge the will accumulate.
The other reason is that coolant has mixed in with the engine oil. This mixing may lead to head gasket leak or even engine damage. Because with mixing up of coolant, engine oil will become contaminated, which significantly will reduce the ability of engine oil to provide lubrication and subsequently will lead to engine failure.

I’d push the starter while it’s running and check for change in noise. I’d exhaust all those type options, then pull the stator cover and start pulling parts off until I get to the starter clutch. That’s just me though.
