hi, I am 13years old and I live in Akadelphia, Arkansas in the united states. I recently traded a bike I built for a schwinn stingray chopper. I have ordered a 80cc engine kit and should be arriving on Monday. I have also found a manual to download off the Internet that tells you how to increase compression ratio And to prevent poblems and improve the kit. I'm thinking about buying some tires with good grip like the nitto series of tires and buying the "poo poo" pipe and the slanted head for it. so far it's a work in the making. I have also learned a lot of fixes to common problems with the kit and I will accept any questions from you.
