I really wish you had not built this. When I first saw the bike, my thoughts immediately turned to building a "special" with a big bore single in place of the original anemic twin motor. Since I read your build thread, my spare titled 360 frame is whispering to me..."build it, you know you want one"! Last night I dreamed about a XR600 powered street bike...you've ruined my life! LOL! It is a very nice bike, nice design and execution. I bet it is a hoot to ride. Anyone have a spare XR600 motor?
