need help with yamaha zinger 4 stalling

[shanksRX-1]

I've got a little zinger 4 that I picked up for my son. It runs great and looks like brand new but when you try to stop it it stalls and the only way to start it is to lift the rear tires so they can spin. I believe it should have an automatic clutch and it should be able to be stopped and still run. Any ideas what I need to do to fix this?? maybe low oil in the base?? Im not sure the base oil plug dosn't have a dipstick on it so I can't check the level...

Thanks....

you might have to take the clutch apart as it sounds like the friction plates/material is stuck so it will not release. had this happen on a couple of old motorcycles we bought. un-stuck them, topped up the oil and a couple of them are still running to this day.
