I would recommend to change out the once you recieve your moped. The it comes with is a Torch A7TC, Brand name is unknown chinese crap. I've searched all over the damn place and it's hard item to get ahold of.
People around here would say change out the engine & trans oil (gear). I prefer to break in my moped first and change it at the suggested 186 miles. At 186 miles use Valvoline Durablend. Synthetic Blend Motor Oil 10w40 or 20w50. I prefer 20w50! Synthetic Blend Gear Oil 80w90. They also have Synthetic Blend Grease if your don't feel comfortable with the chinese crap they used. Here are some pics:
