One of these day's I'm going to "upgrade" from my 1980s cast Yamaha 19's to some 21's. I still think old drum brake dirt bike fronts are the easiest answer. Just take the brake drum out and drill the backside for your spindle and drive pattern, no adapters, welding, gap-bed lathe or milling machine, etc needed, and if you do need to do some machining, you can take the hub out and do it on a normal sized machine.
