Its been a long time since I built Moby, and the last "build" was more of a kit slap, so I wanted to do it right this time. the Motor is built from the ground up, DOS cases, Doppler crank, Le Partie CDI, 70cc Airsal, some sweet vario from Argentina I got from DOS (which requires a pull start, not pictured). So ya let me tell you they are as frustrating as I remember, but I really enjoyed it, its not to fast, maybe 45, but it rips, and eats hills, I really really love this bike!
