Default Noise from primary

Any idea’s what would cause the noise and the damage to outer primary cover (see attached)
bearings look ok/nothing visible.
could not move the shaft after pulling clutch hub.
anyone?

Year and model of your motorcycle would be useful.

Do not see any damage to the primary.

Look at the 1/4 moon cut where you see the orange peaking out.

Make sure that you get the key firmly seated in the keyway on the mainshaft or you will split the flange in the clutch hub.

It`s hard to get an idea of what is pictured when the camera is one inch away.

Model and year?

Is that a copper washer?

If the bike is an 1988 or earlier, that copper washer is the thrust washer for the pinion gear.
