There's stupid trust me, that stupid I'm not sure. Had a guy from north philly call me about a 70cc Chinese quad I was selling from when I had a blast on it. He asked if himself a 6 foot 6 inch 340 pound self could ride it. I just laughed and said no. Then I had a guy travel 2 hours to look at a blaster. He showed up and found out it was a 2 stroke! Wow who didn't know a blaster was a 2 stroke! He wanted a four stroke so right back on the road.
