Ya,,,, that wouldn't be good. It would prob take you a hour to pick up the peices[X(] I got this thing braking 50MPH with that pipe on it. I have the carb just perfect. My friend is a cop and clocked it at 50.2 MPH. Talk about crazy fast. The gearing isn't stock eather. I had to up it when I put the pipe on. It would just sit and spin, if you will. Way to much power. The funny thing is it is just a 23cc. I couldn't even think of how bad a 30cc would be.
