    I installed a Keihin CV on my knucklehead and it runs great, just won't
    start unless I pour gas into the carburetor. After pouring the gas in it
    starts right up with one or two kicks. Once it is started and warmed up
    it runs and idles flawlessly.

    Any ideas?

    Does that CV have an accelerator pump ? If not , get one that does . Had a
    pump-less one on my '88 Sportster , only way to start it in really cold
    weather <below 35 deg or so ...> was to pull a plug and dribble some gas in

    Pull the air filter and twist the throttle . If you do not see a stream of
    gas coming from near the inlet the pump is not working properly . Try a
    "twist kick<while holding the throttle wide open> with the ignition off for
    a prime if you do see that stream of gas . Next kick with throttle closed
    and ig on ...

    There is absolutely no gas going in via the accelerator pump. Do you
    know how to go about fixing it?

    Is this a Keihin CVK? The obvious thing to check would be that the
    enricher circuit ("choke") is connected and working. And just a tip on
    testing instead of "pouring gas" into a carb (especially a side draft like
    your CV(K) is to use a propane torch as the source of fuel (UNLIT OF
    COURSE)......clean and efficient....also a good way to see whether your carb
    is lean or rich.
