Thanks for the input. Much appreciated. I laced up the rear last night and only had one issue. The rear spoke kit for the 400F only has 9 'inner' spokes and 27 'outers.' The first try I put them on the brake side and eventually had problems. I flipped it over and started with them on the sprocket side and it laced up perfectly. Other than that, the rims seemed to work great with the stock hubs.
Going to powder coat with the frame, hubs, rims, triple tree and odds and sods. So excited. Rolling chassis is finally in sight.
