Got a Derbi Senda 50cc 2013 moped which has a whining noise when I drive. I think the whining noise comes from either the transmission or the clutch. The sound does not seem to affect how the bike works, it shifts well, pulls well, works just fine. The sound comes when I drive the bike, but also makes it at standstill in neutral, and when my clutch is activated.
I want to sell this bike, because I already have others with more displacement. But I want to fix whatever is wrong so I can sell it.
Thanks for all your help! Sorry for writing this text so badly, but I am in a hurry.

Can eventually post a file with sound or something when I got time.

Noises are tricky. It's often hard to tell what's going on just by sound.

If it is a new sound that it didn't make before, there is likely something wearing or rubbing.

One way to know for sure is to visually inspect any suspect parts for wear.
