I built an 66cc last spring...drove it all summer long...its been fun...probly put about 5000 miles on it this year...im starting building a few more for realistate agents...the hardest part of this is matching there colors...ex. a blue bike and blue engine paint dont always match these peoples buisness cards...i am a mechanic working currently as a desiel mechanic, but this is now my hobbie...fun,fun,fun...ride fast take chances...dont be a chicken
