new to 50 stunt

[Tattooty]

so i;m buying my first 50 today. picked up a 2006 50 stunt. i've never owned one and i don't know much about the maintenance. i'm sure it's not that difficult but i have a couple of newbie questions. do they use regular gas? or do i have to do a mix? what kind of oil do i use? how often do you have to do maintenance such as oil changes and whatever else? like i said total newb to owning a 50. thanks for the help guys
