Hi Mayf,
Looks like a Demon carb casting and float bowls to me... has anyone fit
one of those in a Tiger?
There are only four injectors, and if they're using a progressive
linkage they can (should) run on only two injectors until you get over
half throttle. Then they're also PWM'ing the fuel pump, and the
injectors will only do their rated flow at the rated fuel pressure, so
they can dial the injector flow proportionally to the intake manifold
pressure by reducing the fuel pump's duty cycle as well as the injector
duty cycle.
