    Fuel injection is all basically Sequential unless you run TBI. It just means they are opened in sequence with the ignition and the right timing. Throttle body fuel injection just dumps in the fuel into the manifold and the valves that are open at that time will just inhale the fuel/air mixture as the piston moves down..

    So...to answer your question...yes they are SFI

    Talking another question...

    Thanks for the reply..

    next question..

    What size are the throttle bodies on the 1300r? i know you can change the injector size (not quite as straight forward as that i know) but what is the max CC's per Cyl (on a big bore engine)recommended before the throttle bodies are to small?

    thanks

    Actually with multiport FI there is sequential and batch.

    Most modern system will start batch firing if they lose one of their reference signals. (eg. cam position)

    With the 1300, who knows, but I am sure WFO knows all of the in's and out's of it.
