Modern Vespa

Hi all, I'm back again with a new problem with my primavera.

All of the sudden, 2 days ago, what sounds to be coming from the rear, wheel a loud ticking interval. It makes the noise forward/backward, with engine on/off. It doesn't make the noise while stationary on the center stand.

Edit: please ignore the chanting noise in background. A school is just on the other side of the street ✌️

I appreciate all the help 🙏

No diagnose / solution until now…

When you move the scooter forward / backward, the only parts moving are the rear wheel, the gears in the final transmission and the clutch bell.
On the center stand or not should not make a difference. It will be the same parts that are moving.

But you state the noise is not there when on the center stand.
This could mean that when there is no load on the rear wheel, as on the center stand, the clicking noise is not there, but when there is load on the rear wheel, from the weight of the scooter, the noise is there.

Did you check if there is any play in the rear wheel when on the center stand?

You might check the FRONT wheel since it's not making the clicking sound on the center stand as it's not moving when on the stand. Or have someone else move the scooter around while You get lower down and try to focus in on what area of the bike it might be coming from, as a place to start.
