So I gather you did a complete tear down and replaced all the seals and bearings, right?
In this process did you also check the rod and crank?
Was the piston to cylinder fit checked?
Was the ring end gap checked as well?
If all was good with these items, then maybe it is a noise from the clutch basket.

I didn't do it myself took it a friend who rebuilds bikes for a living he checked everything and said crank and rod are good! All main bearings seals have been done including rod bearings not that it needed them just got it all done while it was apart! I was thinking that my friend had a ktm 125 with similar noise and it turned out the be the clutch basket bearing, but saying that it really sounds like it's coming from the flywheel and the noise doesn't change when I press the clutch in I'm completely lost with it

Understand that the only rod bearing that could have been changed unless the crank was rebuilt is the top bearing in the rod. I can only hope the person that did the work really checked the crank over real good.
RE: The noise....The clutch bearing or bushing being worn will create a noise that seems to come from the stator side as the clutch side is in oil and the stator side is dry.
You can start the engine and place a long screwdriver handle in your ear and the blade end against the engine on the clutch side and on the stator side to see where the noise is the loudest. It may help you find the issue.
The only other way would be to pull the clutch cover and see if there is slop in the basket.

He checked the crank over and said it's all good and didn't need anything but I said get a new big end veering pressed in while it's all apart just so it's done! But I'll try the screwdriver thing tomorrow it sounds identical to my friends n hat was the clutch! I checked the flywheel for movement again just to be sure and there is still movement in it! Pushing n pulling onwards then outwards there is a bit of play o just want everything perfect then I can take it to tracks without worrying about anything going bang lil

there should not be any play at all in the crank bearings in any direction, if new bearings were installed then you may have a loose fit (bearing to crank) or (bearing to case) but check the clutch any way note: the clutch basket will have a little movement its normal. very little that is.

I have to agree that there should be no movement in the crank in any direction.
