I can't go very long without screwing with something, which is why I cut my seatpost, seattube, brake mounts, bars, headtube and rawed the frame and fork one at a time... Of course I don't really need to, it's just fun and I enjoy riding a little more if I've just put my bike together for some reason. Just check all the bolts every once in a while, and if something breaks, get a new part.
