Weber never made a 52mm but the 48mm will work fine. Stick with F7 etubes, 200 air correctors, 150 mains, 55 bypass, 65/120 idle/holders, 37mm-40mm chokes if you are looking for street use. These are starting points--jetting anyway, but should get you there. Remember you will have better throttle response with the smaller choke (37mm) than with larger ones. Trade off between performance and streetability.
