Let me attempt a translation into English:
_Two days before I broke my foot, I beat a lime green 1978 Puch MK2 2-speed ZA50 with only 800 miles on it. I beat it on a tiny slope hill, and the other moped rider started about five moped lengths away. I have a 1978 Sears Free Spirit, but it had low miles when I got it. I ran high RPM 2-stroke oil which actually made a hell of a difference, and my gear oil was a different choice. It's an E50, but holy shit does it go fast when you go long enough distances. How do I mess with the gearing?_
