What could be wrong with my CPI GTR 50?

Hi,

I have a CPI GTR 50 built in 2004.

Speedometer says 6000 km mileage

(2-stroke, Euro 2, Minarelli lying/horizontal)

The scooter has probably been sitting for several years. It currently has a license plate from 2009. I wouldn't be surprised if it's only been driven sporadically since then, let alone started.

Overnight, out of the blue, he started making the following noises:

When I turn it off, I hear a metallic ringing sound, which alerted me to the clutch.

I then opened the Vario housing and found the following:

Additionally, the scooter vibrates heavily when idling. This led me to the crankshaft.

What do you think? Is this engine failure? A crankshaft failure? Or "just" the clutch?
