1. An electronic fuel injection body, comprising:
a throttle body having an upper inlet and a lower outlet, said throttle body configured to mount to an internal combustion engine;
a first bore of a first size extending between said inlet and said outlet and a second bore of a second size extending between said inlet and said outlet, said first size and said second size being different sizes, wherein one of said first bore or said second bore is a primary bore and the other of said first bore or said second bore being a secondary bore;
at least one first fuel injector disposed at least partially within said throttle body and adjacent to said first bore;
at least one second fuel injector disposed at least partially within said throttle body and adjacent to said second bore;
each of said first bore and said second bore having a respective fuel distribution ring which receives fuel from one of said first or second fuel injectors, each said fuel distribution ring having a plurality of fuel apertures which provide fuel into said first bore or said second bore for mixing with an airflow;
each of said fuel injectors extending into said throttle body horizontally;
a throttle valve disposed within each of said first and second bores;
a first throttle lever extending through of said first bore and a second throttle lever extending through said second bore, each of said throttle levers having one of said throttle valve, each of said throttle lever rotating to control a position of each respective said throttle valve, and further wherein said first throttle lever and said second throttle lever open said respective throttle valves at different rates;
a first fuel component cover disposed on said throttle body and having at least one fuel passageway therein which is in fluid communication with an exposed portion of said at least one first fuel injector;
a second fuel component cover disposed on said throttle body and having at least one second fuel passageway therein which is in fluid communication with an exposed portion of said at least one second fuel injector.
