Most people make the manifolds too flat. Modern bike carbs are usually designed to run at 45 deg or more.
so what will work better? for throttle bodies.
1. manifold as above,injectors pointing at the opposite side of the manifold and at 90 deg to the head,so the air has to flow around that 90 deg
or
2, standard st170 injector manifold,with the injector pointing at the back of the valves,inlet manifold at 45deg to the head,air flow pointing at the back of the valves.
