    Hoping someone can help a couple of rookie mechanics.
    I have a Interceptor VF500R that I can't get running....seams to be a
    fuel issue.
    We have replaced the fuel pump, the fuel on/off switch, and have
    bypassed the fuel relay switch. It still wouldn't start.
    If we unplug the fuel line from the gas tank and drop it into a can of
    gas....bike starts right up. What, besides the fuel on/off switch
    (which has already been replaced) could cause the bike not to start?
    There is a hose (smaller than the fuel line) that runs from the on/off
    switch. Seams to be some type of vacuum line. What is it's purpose
    and what does it run to ?

    Any help would be appreciated.

    It is a vacuum line and it controls the fuel valve on the tank. It
    should connect from the fuel valve to a nipple on one of the carbs or
    somewhere on the intake tract. I don't know where it is on your bike
    but I am reasonally sure it is there. Check the carbs nearest to the
    fuel valve. Hope this solves your problem, let me know.

    You can test the vacuum operation by applying vacuum to the line while
    the bike is off, and the fuel hose is set to drain into a can. If
    applying vacuum starts the flow, and if flow ceases when you release the
    vacuum, everything's working right. If not, they you either rebuild or
    replace the petcock (they're usually simple and cheap to rebuild). For
    sure check out the sabmag site (sabmag.org) for more info on these sorts
    of V-4 hondas.

    Thanks for the info !! I have another question.....

    I have taken the petcock to a bike shop to be tested....it tested out
    ok....so I don't think that is the problem.
    Is there anything else that could affect the vacuum ?
