Throttle limiter?

[Bobby-V]

I got a Gio Pocket Dirt Bike for my 6 year old son. It was delivered with almost everything (no front number plate mounting bracket). Other than that it went together easily (with loctite of course). Took a couple of pulls for the first start. After that it starts and idles beautifully. I was shocked at just how much power this thing has!!!!!

Having said that. Is there a throttle limiter on the bike? If not is there a way I can rig one up? Last thing I want is something that will harm my son's confidence in learning how to ride rather than build it up.

Any suggestions on oil as well? I used Lucas Oil high performance 2 stroke oil at 25:1 but again I am open to suggestions.

I will say this about the machine - she wants to go.
