I am in the process of tearing down my sons xr 70 and rebuilding everything on it. I have never done anything like this before but so far it has been pretty fun. I had the frame and the hubs powdercoated, rebuilt the motor with a kit from tboltusa (awesome customer service btw), new bars, graphics, tires, grips, seat, springs from BBR and a few other things here and there. I will post pictures as I progress. It should be a lot of fun.
