I've only had this bike for about six months. I ride it I get the chance. I'm nothome alot to ride, stupid army with it not letting me ride my baby. Anyways it cranks and cranks and I get an occasional fireball outta the tailpipe. I'm not a bike genious by anymeans. I can take things apart but I don't want to go too far without having some ideas. Any fresh perspectives would be great. Thank you. I'm sure some of you already answered a question or two like this one but I haven't located one like mine yet.
