Dual Injection Throttle Bodies???

Post by cOoTeR » Fri Dec 15, 2017 1:26 pm


Can someone explain what the Dual Injection throttle bodies are that com on the H2 models (40mm on H2 SX, 50mm on the H2) and how they are different from the 44mm throttle bodies on the ZX14 that does not mention "Dual Injection"?

As far as I know most modern sport bikes come with two sets of Fuel Injectors. Is that what they are referring to when they say Dual Injection? Or is it something to do with the throttle bodies themselves?

They sound similar to the ZX-10R setup. THere is 1 set of injectors in the throttle bodies and 1 set on top of the manifold/airbox, aiming at the velocity stacks. Provides better fuel atomization. I know manufacturers have been doing this since at least the late 90s as my old 99 TL1000R had dual injectors and my ZX-10Rs had it as well.
