I am in the process of switching to spokes currently on my 77 750f. I am going to use 1976 cb750 hubs so I can keep the rear disc. I have ordered Sun rims and stainless steel spokes from Buchanans. I have the hubs but waiting on the rest of my parts to complete the switch. I will try to document anything unusual that comes up along the way, but I may wait until the weather completely changes to winter before I complete it.
