Instead of selling my Riva Powerbomb I have been considering just buying another to use for a dual carb setup but am not sure if it will work. I know that OEM carbs are not allways the same and should not be mixed and matched even when the same size/design is used. My question, if anybody knows, can I purchase another powerbomb and run it side by side with mine and be sure that they are internally the same? My carb is silver where most I have seen are black, not sure if that makes a difference. I plan on calling Riva today but have to wait till they are open, any input is welcome.
