If you can't talk the parents into taking these things away outright,
you can limit their power. Many years ago (early 1970s) Mitsubishi was
importing mopeds. They were making too much horsepower to be legal for
unlicenced use. A friend came up with a very simple fix:

He made an aluminum plug that fit tightly in the exhaust pipe, and
drilled a 1/4" hole in it. Surprisingly, the engines ran fine, the
mixture was fine and the power was limited just enough.

You'll probably want a much smaller hole - zero sounds like a good
size.
