I have a nice set of 2001 Yamaha R1 motorcycle throttle bodies for sale. They are all complete with the injectors, wiring, etc. The throttle side has blades (40mm) and the inlet side has slides (43mm).
I had picked them up to do a Megasquirt fuel injection setup on a BMW M10 4 cyl. engine. I think I'd rather stick with the carb version for this one.
If you were considering an ITB type project with MS(megasquirt), this would be a great way to go.
