Baja Doodlebug ID.

So I bought a Baja doodlebug from CL for my son the other day. I wanted to get some replacement parts that are a little messed up like the throttle cable and the throttle return spring. It looks like it's stock but it runs great with my boy on it. He can even climb hills with it. Anyway, I wanted to verify with somebody the right year/model of it before I ordered the parts I need. I'm pretty sure it's a standard DB30. It has a 97CC engine. The serial number has some stuff blocking only the first letter I think on the front handlebars but the rest is UAHYG10781036765. I attached a pic too. Thanks!
