    G'day
    I've taken apart a set of carbies for an FZR250R and have managed to destroy two of the emulsion tubes that live underneath the main jet in the jet block. I had a look online and had some greatly appreciated help from Adrian at Percy Jack Motorcycles in Marrickville but can't find any of these parts online. Does anyone have a set of these they'd be willing to part with? Or, does anyone know where I can find some online, or even a substitute? I'll add the exploded diagram of the carb, the part is labelled number 42, and its part number is 3LN-14148-20.
    Thanks, Tevita

    Was nice to meet you in person.

    @GreyImport got any spares to resurrect this 3LN7?

    Ive never had that tube out of the jet housing as I always presumed it was a press fit .... theres no "screw head" .... what you see is more like the other end ..... now all of my carbs here and parts are early model .... 3LN1 , so maybe it was another carby design change for the later bikes

    @Linkin does the pink bitch have those removable tubes?

    I don't know, never attempted to remove them on any that I have owned.

    3LN1 does have them but part number is a different prefix

    3HE-14148-00

    Both are NLA

    @gyro gearloose How did you successfully extract these from under the main jet? Thanks

    @Linkin ... Megazip are using the wrong schematic .... if you look at #34 on both , as much as the "drawings" are pretty shoddy , you can see the old and new style jet needle setup.

    I have that "original" 3LN1 parts book .... its of course a copy .... it came in a box of extras with one of the FZRs that came thru the Fizz Factory back in the glory days :cool:

    Edit:
    There u go ... came with the pink bitch :lolsign:

    Thanks for the help guys I appreciate it. I think I'll get my hands on some of the Zeal jet blocks and put the jets for mine in it and see how I go.
    Thanks, Tevita

    Looking at those emulsion tubes with the main jet still in the emulsion tube that have been extracted - it looks like the main jet is still screwed into the emulsion tube itself...

    Something is odd...
