There's a kid at my school trying to sell a dirtbike. He says it runs but idle really high. He doesn't know how to fix it. So I might buy it for $110. Can't really go wrong at that price. But the thing is he doesn't know what it is. All he knows is that it's an 80cc Suzuki. He doesn't know the year, he THINKS it's a 4 speed but it might be 5. He is pretty sure it is a 4 stroke. So my question is, does such a thing exist? I'm going to look at it tomorrow. He's some rich kid so I doubt it's in bad condition because he was probably too scared to ever ride it fast or hard.
