So I just purchased my third moped last week, and I'm thinking that it needs some help so it can keep up with the hobbit and the mobylette. I got this puch and I want to build it up so it is fast and reliable. What are some good cylinder kits? I see that 1977 has that 80cc jobber, but is that thing going to give me headaches? my padre has a machine shop so fitting it should be an issue. What about exhausts? I was thinking of using a little makuni flatslide i found in his shop... suggestions would be appreciated
