My cousin just got this Doodlebug with a 110cc Lifan and 4speed running, and I got to ride it today and I must say, Im impressed as all heck! Though I think it needs a few tweaks, like a steering dampener since it gets sketchy over 40, but overall its a super fun ride. It's a mostly stock DB30 frame with custom mounts, CRF50 exhaust, 35t sprocket, and a shortened Buell Blast clutch setup. He might sell it or build it a bit more, what do you think something like this is worth?
