so my friend has a 50cc 2007 yamaha aerox. it's great, pretty much stock, but the variator keeps untightening. i don't know much about scooters, because i'm more used to mopeds and old bikes.

It's either missing a locking washer/split pin or you are supposed to use threadlock fluid.

I'd be more inclined to think it's the former because undoing a variator with threadlock on it would be a complete arse.

it doesn't have one. i think the kickstarter gear which grips the variator to start the engine doesn't go back, so it slowly untightens it. i don't really know what the problem is, i drive a chinese 4t which i bought brand new and haven't had any problems with, so i don't have much experience with scooters.

Well, here's a exploded diagram of your sons bike. Is anything missing?

BTW a one way clutch is exactly that, it only works one way.

Edit: If the kicjstart doesn't go back into position then theres something wrong with the spring or how it's located.

Once again, half a story....
