Fuel Pump Question

Discussion in 'Australian Motorcycles' started by Andrew McKenna, Sep 22, 2010.

  1. The son who now owns my old Z750 popped round to say hello. We chatted,
    he left, and on the way home he ran out of petrol. I rescued him, and
    after he got home he noticed that there was a high-pitched squeal coming
    from the fuel pump.

    The shop says the fuel pump bearings are lubricated by fuel passing
    through, and if you starve the pump of fuel, you stuff it, and you need
    a new one. I read somewhere that you should avoid running out of fuel on
    a fuel-injected bike, and I guess this is one of the reasons.

    The question is: can he still ride the bike for the 4 weeks it's going
    to take to get a new fuel pump, despite the squeal, or is the pump now
    likely to break into tiny fragments at a moment's notice?



    Look, look: a post entirely about motorcycles!

    It will run for months if my experiences with bimmers are a guide
    then just stop behind the black stump when run low again
    I replaced mine with a 4100.00 foulcan pump as the near identical
    bimmer pump was $400.00 coming with some gortex to mount it , guess what
    I said to that

    My SV ran with a whistling fuel pump for a little while, although, being the
    paranoid person I am, every trip was a nightmare.

    Dat's ok. I just thought you meant a pump from a 4.1 Falcon!

    I think he did.
    BM pumps are fairly generic; I doubt Jap owners would be so lucky.
    Best thing is to have a trawl through Kwakka forums and groups; it's
    very unlikely you're the first in the world with the problem.

  10. I have grown used to Atec-isms over the years, but that one has me
    completely baffled. Can you please explain?

    I took it as a Murphy's-law-ish "it will fail when you're furthest from
    help" but it could also have been a reference to black -> charcoal ->
    charcoal-cannister or maybe even some sort of stumpy stopper-shaped
    sex-device up the back end.
    It's probabably safest to just pick one and move along.

    ever been to the black stump ?
    great place to break down or hole the sump in your car or have a fuel
    pump fishizzel out

    do you need matchsticks ?

  13. Ah. [Lightbulb]. You're not telling me to stop behind the black stump,
    it's the bloody fuel pump that stops. Apologies for being thick.

    yup, check the Kawa forums

    most Suzuki pumps are Mitsubishi.. dunno about Kawa

    is it a in tank unit? if not there are that many aftermarket units,
    Facet make very good ones that can be retro fitted, Facet is a major
    supplier to the aircraft industry

    the KTM950 stock pump is well know for shitting itself, well the
    contacts do (its a Mitsubishi not a KTM) and the common fix is a Facet
    worth $60 USD

    If there is a mod or a cheap way out, it will be on a Kawa forum

    Kawasaki for some reason seem to be less willing to do running model
    improvements than the other Japanese manufacturers and they have keep
    some models in the line up for a very long time.

    I suspect that gives people more time and a better chance to come up
    with 'cheap ways out' or around problems, hence the greater prevalence
    of such solutions on the net.

  17. V-Strom uses a Mitsubish pump. Available at motor factors for 1/10th the price
    of a suzuki one.
