Moped Army

don't think i'll upgrade the pipe. the stock expansion chamber is decent but not great. i only want to be able to do 70 on this bike. spending another 300 bucks on a pipe just isnt worth it to me right now. maybe in the future if i come into a large sum of money from a rich uncle.... maybe. or if motomatic wants to donate one... ha

besides i dont want to blow it up. if i keep the stock gearing, it'll be screaming at 14k rpms at 70. with new gearing i'd like to keep it at about 10k at 70mph.
