I was going to have them welded when the welder does my runners...where can I get a factory flange at a good price? Trying to keep the price down because I'm just going to be turning around and selling these as soon as they are done. I'm only building them for the experience of it.

Also, those are the factory honda CAR injectors in the factory BIKE injector holes. That factory fuel rail even worked and upon research, the bike fuel rail pressure is 50psi which is plenty for the honda fuel system. I am going to have a custom fuel line built to run from the rail to a fuel pressure regulator. This would be a returnless system so it would have to be hooked up like a K series swap.
