Does the noise persist when the vehicle isn't trying to move? (in neutral) Does the noise change based upon whether you have the clutch lever pulled in, and/or are in 1st/2nd/3rd/4th/5th/6th gear?
The noice has happened while in neutral off a cold start and has also happened while already in 3rd right after I had just shifted from 2nd.Does the noise persist when the vehicle isn't trying to move?

Yes the bike behaves as if the engine is taking extra load the oil is good no debris in the oil at all and the noice sounds exactly like if a belt has gone bad on a car and it starts screeching that’s the exact same sound it makesI'm assuming whether the clutch is held in has no impact.
Does it behave as though the engine is facing extra load when the noise ensues?
Oil levels are normal? Any debris in the oil?
Do you have an audio recording of the noise? I can understand not wanting to run it again, but perhaps you can locate a similar recording; or mention a similar noise that we could all relate to.
