Found on the 2005 Kawasaki ZX-6R and ZX-6RR. Also use two injectors per cylinder, on just after the butterfly and the other way upstream pointed straight at the throttlebody. I can post a pic of the injector setup if you want. BTW throttlebodies are 38mm IIRC.

 

injectors after butterfly= better response at low RPM

injectors before butterfly= better fuel atomization and more power in the upper RPM ranges

edit- switched them around, my bad.

I thought it was the other way around?

I.E. the injectors that are way before the butterfly and thus far from the intake port help high rpm power because the fuel is atomized better, but at low rpm the closer injectors (post-butterfly) give better throttle response and power...

 

I think you got it right as far as the before throttle plate(as far as airflow would be moving). Most likely a mistype by RPM. Too bad they're not ovaled width wise or they'd be perfect for our ports! These would make it even more difficult in adapting to a flange, now you'd have to crush one end for the ports and then perpendicular to that crush you'd have to crush again! lol
