    I'm looking for carb rebuild kits for my '81 xj550
    I found them at old bike barn for $19.95 a pop. Once you add shipping though I'm looking at like $90-100 bucks for the whole job. Does anybody know where to find them cheaper? Or better yet, is it even necessary to rebuild if i do a good cleaning instead?

    Kits vary a good deal in content. Chacal on this site has every part you could need at reasonable prices and shipping rates and he turns orders fast. Just PM him with your needs.

    You can do a good clean without a kit as long as all your seals and o rings are in good shape. I did mine twice then just rebuilt replacing everything. Huge difference when I did but everyone had different needs.

    Here they are, along with a few other items you might need:


    MIKUNI CARB REBUILD PARTS:


    NOTE: Mikuni carbs were originally used on all Yamaha XJ550 models (BS28 series carbs), all XJ650 Turbo models (BS30 series carbs), all XJ700-X and XJ750-X models (BS33 series carbs), XJ900RK model (BS35 series carbs), and XJ1100 models (BS34 series carbs). All other XJ models from this era (XJ650 non-Turbo models, XJ700 non-"X" models, and all XJ750 non-X models) used Hitachi carbs.

    NOTE: "OEM" refers to an original Yamaha factory part, whereas "Replacement" or "Aftermarket" refers to a part not made by Yamaha or one of their original suppliers. NOTE THAT AN "OEM" PART may be made by Yamaha's original supplier, even though such part is no longer serviced through the Yamaha factory parts system.


    j1) XJ models Mikuni BS28/30/33/34/35 USED PARTS.....jets, bowls, bodies, diaphrams/slides, floats, brackets, screws, etc. I have multiple used sets of carbs that I can part out for the items that you need, let me know what specific parts you're looking for.



    MIKUNI THROTTLE SHAFT REBUILD PARTS:



    MIKUNI THROTTLE SHAFT SEALS:


    aaa) OEM and aftermarket Mikuni carb THROTTLE SHAFT V-SEALS (sometimes called an "O-Ring", but it's not!)...these are the seals on the outside of the carb body that the throttle shaft passes through. Uses 2 per carb, BUT......without taking the carbs apart from the rack, the only ones you can replace are the outer seals on the #1 and the #4 carbs. Unlike the QR-series "o-rings" that many people recommend using---AND WHICH DO NOT FIT PROPERLY---these "V-Seals" do have the correct O.D., I.D., and thickness to fit both the throttle shaft and the carb shaft seal bore recess correctly. Used on all XJ550, XJ650 Turbo, XJ700-X, XJ750-X, XJ900RK, and XJ1100 models.

    $ 25.00


    COMMENTARY: These seals are a VERY common source of vacuum leaks into the carbs, making tuning (synch, colortune, etc.) somewhere between very difficult and next-to-impossible. And here's the dirty little secret that no one really talks about:

    If you read through these boards often and enough---or any other websites or lists devoted to these XJ bikes----you'll find a common theme in regards to these bikes, and it goes something like this:

    "My bike doesn't run right."

    And 9 times out of 10, it's due to a carb problem. And to make matters worse, these bikes don't just use one carb, they use four, which means that the synchronization of the four carbs to each other is critical in order for them to perform properly.

    And 95% of the problems with the carbs is this: they are dirty (more like filthy!) inside due to age, and these seals are worn out. But to replace these seals (and also to properly get the insides of the carbs absolutely, positively, ZESTFULLY! clean), you're gonna have to pull the carb rack apart. Although that task is not mechanically difficult....nor does it take any special tools to do it.....the re-assembly process will MERCILESSLY PUNISH the careless or impatient mechanic or hobbyist. A tremendous attention to detail and organization is needed before you begin to take these carbs apart, so that you will have all the proper notes, drawings, sketches, etc. to put humpty-dumpty back together again, properly.

    Since most people lack those skills or discipline, you will find most of the experienced experts on the various boards and forums telling you to NOT take the carbs apart, and to forego the proper cleaning and parts replacement steps needed.

    I'm not trying to tell you to do, or not to do the task properly yourself; all I can tell you is what my own personal experience is. If you have the proper tools, time, and organizational skills and the PATIENCE to do the job right, breaking a rack apart and doing the job properly isn't that difficult. If you don't, it's a nightmare.

    And the other dirty little secret is this: before you can synch and tune your carbs properly, you MUST check and adjust your valve clearances (replace worn valve shims), or all the synching and colortuning in the world isn't going to give you optimal results.

    Sorry to be the bearer of such bad news, but as always, the truth will set you free (or at least solve most of your tuning and performance issues!).

    Luckily, all of the parts and special tools needed to perform a proper tune up ARE available. I guess we should appreciate the little things in life more than we usually do........



    bbb) Aftermarket Mikuni carb Throttle Shaft Seal PLASTIC SHIM WASHER...these washers go directly "outside" of the throttle shaft seals listed above. Same notes as listed above about the seals (regarding the ease of replacement) also applies to these shims. NOTE: these shims do NOT "wear out" like the seals do; you only need to replace them if your shim washers are broken or missing. Used on all XJ550, XJ650 Turbo, XJ700-X, XJ750-X, XJ900RK, and XJ1100 models.

    $ 2.00

    $ 3.75

    HCP39CSET8 Aftermarket Mikuni throttle shaft seal SHIM WASHERS, eight shims:
    $ 14.00





    MIKUNI THROTTLE SHAFT HARDWARE:

    ts5) Aftermarket Mikuni throttle shaft BUTTERFLY VALVE MOUNTING SCREW. Each round butterfly "valve" is held to the steel throttle shaft via two tiny phillips head screws. The throttle shaft has self-locking threads which makes the removal of these screws an absolute chore and usually results in a buggered phillips head slot. These replacement screws come in a variety of materials and drive styles. Use 2 per carb, 8 per entire carb rack. Used on all XJ550, XJ650 Turbo, XJ700-X, XJ750-X, XJ900RK, and XJ1100 models.

    NOTE: these screws are an absolute BEAST to remove, and it is very easy to destroy the screw heads as well as the throttle shaft threads while trying to remove them---if proper precautions are not taken. You will want to review the information in this forum thread before attempting removal:

    http://www.xjbikes.com/Forums/viewtopic ... html#66348


    For all of the above reasons, our recommendation is to use the allen-head (hex drive) style screws (HCP7120 or HCP7346 below) to make future removal easier. ALSO, since it is not really feasible to peen or stake the screws once installed (as Mikuni originally did---they must have had a special fixture to perform this task), it is strongly recommended that you use some type of semi-permanent thread-locking fluid (such as our HCP1266 or HCP1267 thread locker fluids) when installing these screws.....as the last thing you want to have happen is having these screws back out during engine operation.....as that would be a sad, sad day for you and your engine!

    MIKUNI IDLE MIXTURE SCREW PARTS:


    NOTE: idle mixture screws are also referred to as "pilot mixture screws" or "pilot screws".

    If you've never delved into the guts of your carburetor idle mixture screw port, it can sometimes be confusing. Here's the playbook for this critical area:

    If we were looking at a cut-away of the carb body/idle mixture screw bore, the order of parts, from bottom to top, would be:

    a) HCP895 o-ring
    b) HCP896 spring seat washer
    c) HCP6574 tension spring
    d) the idle mixture screw
    e) the metal anti-tamper cap.

    What is mostly confusing is the order of the o-ring versus the spring seat washer....which goes in the hole first? The answer is that the HCP895 O-ring does. The HCP896 washer primarily acts as the lower "seat" for the HCP6574 tension spring, while also keeping the o-ring firmly and securely in place.



    ims3) OEM Mikuni IDLE MIXTURE SCREW SET is correct for all original XJ550, XJ650 Turbo, XJ700-X, XJ750-X, and XJ900 carbs.

    Each complete set contains one brass slot-headed idle mixture adjustment Screw, the mixture screw Spring, the spring Washer, and the sealing O-Ring. NOTE: the tension spring contained in this kit is not the correct length for the XJ650 Turbo, XJ900RK, or XJ1100 models, but will work.

    HCP3745 OEM Mikuni IDLE MIXTURE SCREW SET....contains the brass idle mixture screw, spring, spring washer, and the o-ring. Each:

    $ 17.95




    MIKUNI IDLE SPEED SCREW PARTS:

    Not to be confused with the idle MIXTURE screw listed above, the IDLE SPEED SCREW is the large knurled-head screw that lives dead center, at the bottom of the carb rack, in-between the #2 and #3 cars, and pointing straight back. This screw is used to adjust the idle speed of the engine, and has no effect on the idle mixture nor the carb (engine) "synch" settings!


    HCP5161 OEM idle speed ADJUSTMENT SCREW AND SPRING SET, fits all XJ550, XJ650 Turbo, XJ700-X, XJ750-X, and XJ900RK models.
    $ 22.95


    HCP9848 Aftermarket Mikuni idle speed screw rubber GROMMET, fits into the lower carb rack bracket opening where the idle speed screw enters the bracket. This replacement grommet is quite a bit larger than the stock grommet, but fits and works properly. Use a little bit of silicone grease on the screw's shaft where it passes through this grommet and it will be silky-smooth in operation. Fits all XJ550, XJ650 Turbo, XJ700-X, XJ750-X, and XJ900RK models
    $ 1.95


    HCP4024 Aftermarket Mikuni carb idle speed screw WASHER, not an original part, but if you use a set of these thin flat plastic shimming washers in-between the spring and the screw, and between the spring and the bracket (in other words, on either end of the spring), it greatly reduces the friction between the two and makes the idle screw silky-smooth to adjust! Fits all XJ550, XJ650 Turbo, XJ700-X, XJ750-X, XJ900RK, and XJ1100 models Each:
    $ 0.75




    MIKUNI CARB STARTER-ENRICHMENT CIRCUIT-CHOKE SYSTEM PARTS:

    The starter (choke) circuit is prone to a number of problems, from clogged passages in the starter jet (down int he bowl) to worn or fractured plunger valves and their related hardware. We've got some of those hard-to-find parts to properly restore your system.

    The starter circuit PLUNGER VALVES are the solid brass needle-tip valve that actually shuts off or opens the enrichment circuit. Worn tips or fractured heads renders these valves useless. These valves are SPRING-loaded, and retained in the starter valve port in the carb body by a threaded, hollow-center brass SEAT, which is then surrounded by a small rubber DUST CAP. In addition, XJ650 Turbo models used a rubber O-RING to provide an air-tight seal at the cover-to-carb body mating surface.


    HCP5197 OEM Mikuni brass PLUNGER VALVE, fits all XJ550 models, each:
    $ 16.25

    HCP9933 OEM Mikuni brass PLUNGER VALVE, fits all XJ650 Turbo, XJ700-X, and XJ750-X models, each:

    $ 1.50

    HCP9846SET4 Aftermarket starter circuit plunger seat O-RINGS, correct for the XJ650 Turbo models (o-rings were only used in this area on Turbo carbs), set of 4:
    $ 5.00



    HCP9335 OEM Mikuni brass plunger valve threaded brass seat DUST CAP, fits all XJ550, XJ650 Turbo, XJ700-X, and XJ750-X models, each:
    $ 6.95



    HCP9895 OEM Mikuni brass PLUNGER VALVE SET, contains the brass plunger Valve, the Spring, the threaded brass Seat, and the rubber seat Cap. Fits all XJ650 Turbo, XJ700-X, and XJ750-X models. NOTE: the threaded brass seat that comes with this set is not correct and will not fit the XJ650 Turbo models. Each:
    $ 44.95



    MIKUNI FUEL AND AIR JETS:


    MIKUNI MAIN FUEL JETS:


    ee) OEM and aftermarket Mikuni brass MAIN FUEL JETS, sizes as follows, fits all XJ550, XJ650 Turbo, all XJ700-X and XJ750-X, XJ900RK, and XJ1100 models.

    NOTE: stock Mikuni XJ series carbs used the following original main fuel jet sizes:

    #100 1985 all XJ700-X models
    #102.5 XJ900RK US & Canada
    XJ550L (1984) on cylinders #3 and #4
    #105 1986 all XJ700-X models and all XJ750-X
    XJ550L (1984) on cylinders #1 and #2
    #107.5 XJ900 1983-84 except USA or Canada
    #112.5 XJ550 all models and XJ1100
    #127.5 XJ650 Turbo carbs for cylinders #1 and #4**
    #132.5 XJ650 Turbo carbs for cylinders #2 and #3**

    **NOTE: there is conflicting information between original and re-printed service manuals and the factory parts manuals concerning the size of the main jets for the XJ650 Turbo models. We have tried to provide the most accurate information available to us above. Some manuals call for the use of #125 main fuel jets on the #1 and #4 carbs, some call for the use of #130 main fuel jets on the #1 and #4 carb, and a #135 main fuel jet on the #2 and #3 carbs. What we believe to be correct is the #127.5/#132.5 combination of jet sizes as listed above.

    All the other sizes are for "tuning" or re-jetting purposes when changing intakes or exhaust systems.

    MIKUNI MAIN AIR JETS:

    Alas, the Mikuni BSxx series carbs used on XJ models---unlike their cousins the Hitachi HSCxx series carbs---did not have replaceable main jets. The main air jets on these models are in the carb throat, facing the airbox, and are a small, brass pressed-in tube that is non replaceable, and which we suggest you do NOT try to modify by drilling or enlarging.

    And just in case anyone is wondering, here are the sizes of these non-removable main air jets in the various models:

    #45: XJ900RK
    #70: XJ550 all models and XJ650 Turbo models.
    #120: XJ700-X all models and XJ750-X all models*
    #140: XJ1100 models*

    NOTE: we believe that the #120 and #140 sizes listed in the service manuals (from where the above information was gathered) may be incorrect, as these are gigantic sizes for main air jets. But since you can't replace them anyway, I suppose that it doesn't really matter........

    WHAT ABOUT RE-JETTING FOR PODS, ETC?:

    It's a question we get asked often and unfortunately, one that we cannot answer honestly about your specific bike besides with "it depends".

    Which is a nice way of saying "you're about to enter the seventh circle of hell......."!

    Carb jet tuning required by aftermarket modifications is somewhat of a black art, part science, part skill, part luck. It depends on the current state of tune of your engine, your altitude, the mix of aftermarket parts on your bike, etc........a lot of variables.

    The best advice we can offer is: Just Say No. Don't do it! Leave everything stock!

    But, since most people---with good reason, I might add---don't always listen to our well-intentioned advice, then the next best recommendation we can offer is: "if you want more power get a bigger bike!".

    And since that doesn't cut it with many owners, either, for the remaining stalwarts out there who insist on "experimenting" with aftermarket intake and exhaust systems, here's the best information that we've come across to give you some GUIDANCE, which you should take as just that, and not as ANSWERS, because it isn't!



    MAIN FUEL JET SIZE CHANGES NEEDED PER TYPICAL MODIFICATION:


    Typical Exhaust Changes:

    +2 main fuel jet size for custom 4-into-2 exhaust

    or

    +4 main fuel jet sizes for 4-into-1 exhaust

    or

    +4 main jet sizes for no muffler (open headers)


    Typical Intake Changes:

    +2 main fuel jet sizes for single K&N filter (inside a stock airbox)

    or

    +2 main fuel jet size for drilling holes in the airbox with stock filter

    or

    +4 main fuel jet sizes for individual pod filters (no airbox)



    Additional changes:

    - Add up all the main fuel jet size increases and subtract 2 sizes.

    - Decrease main fuel jet size by 2 sizes per every 2000' above sea level.

    - Under a mis-match condition, such as when using pod filters with a 100% stock exhaust, or 4-into-1 header with stock filter and air box, then subtract 2 main fuel jet sizes.


    PILOT FUEL JET SIZES CHANGES NEEDED PER TYPICAL MODIFICATION:

    Pilot fuel jet size changes are related only to the change in main fuel jet sizes according to the main fuel jet size formula described above. Note that this pilot fuel jet rule is for the main fuel jet size change BEFORE any main fuel jet altitude compensation is factored in:

    Increase the pilot fuel jet size +1 for every +3 main fuel jet size increases.

    Additional changes:

    - Decrease pilot fuel jet size by 1 for every 6000' above sea level.



    PRECAUTIONS:

    - Make sure your carbs are in perfect working order before making jet changes....meaning fully cleaned internally and rebuilt, operating properly in their stock configuration, proper sized air jets and needles, etc.

    - Check plug color often and adjust as needed, 2 main fuel jet sizes at a time and 1 pilot fuel jet size at a time. Bright white plug insulators are a sign of an overly lean fuel mixture condition and WILL cause damage to your engine over time, up to and including engine seizure!

    - Synch the carbs after each jet change.

    - Make sure the floats are set correctly

    - Seriously consider purchasing a Colortune Plug Tuning kit.

    - You may find it necessary to make changes to the size or shimming of the main jet needle. There are no guidelines on what or how to do these changes, this is true trial-and-error tuning!



    EXAMPLE:

    A 1982 XJ550RJ Seca using an aftermarket Supertrapp 4-into-1 exhaust and a single K&N air filter in the stock, unmodified airbox. Bike is primarily operated at an altitude of 2600 feet above sea level.

    XJ550 Seca Stock Mikuni BS28-series Carb Jetting:

    #112.5 Main Fuel Jet
    #35 Pilot Fuel Jet
    #70 Main Air Jet
    #170 Pilot Air Jet
    4GZ11 Needle


    MAIN FUEL JET SIZE CALCULATIONS:

    Changes made:

    Exhaust:
    4 into 1 with Supertrapp = +4 Sizes Main Fuel Jet

    Intake:
    K&N Pod Filters = +4 sizes Main Fuel Jet
    ----------------------------
    Equals: +8 main fuel jet sizes above baseline
    Subtract: -2 main fuel jet size per formula above
    ----------------------------
    Equals: +6 main fuel jet sizes due to modifications, thus:

    Stock main fuel jet size is: #112.5
    + 6 additional sizes
    = a #118.5 main fuel jet size
    ---------------------------
    Subtract: -2 main fuel jet sizes for Altitude of 2500' Average

    = #118.5 calculated from above
    -2 jet sizes for altitude adjustment

    = a #116.5 main fuel jet size.


    PILOT FUEL JET SIZE CALCULATIONS:

    The formula is: +1 pilot jet size increase for every +3 main jet sizes increased.

    Stock pilot fuel jet size is: #35
    + 2 additional jet sizes (since we went up +6 main fuel jet sizes before the altitude compensation was factored in):

    = a #37 pilot fuel jet size.

    Note that no altitude compensation is needed on the pilot fuel jet since our elevation is less than 6000' a-s-l.


    ------------------------------

    RESULT:

    A #116.5 Main Fuel Jet and #37 Pilot Fuel Jet is A GOOD STARTING POINT.

    ******************************************************

    Note that the above calculations do NOT take into account any possible changes in the sizes of the air jets nor the main needle size, which are additional variables and opportunities for tuning excellence (or frustration!).

    For further insights and understanding, the Holy Grail (meaning: the whole miserable, un-varnished truth of what a real chore carb tuning is going to be, written by people who actually know what they're talking about, rather than by people who are trying to sell you something) can be found at:

    www.factorypro.com

    and then click on the "Product Support/Technical Support" link at the top of the page, then on the "Motorcycle Tuning Tech" link, and then the "CV Carb Tuning" link........and then read, weep, study, and do....if you still dare to! As you will soon realize, it's takes quite a bit of effort to properly tune a carb to its optimal performance----another reason why we don't suggest using pods!




    MIKUNI MAIN JET NEEDLES:

    mjw1) Aftermarket Mikuni main jet needle TUNING WASHERS, these precision ground 18-8 stainless steel shim washers are used to raise the main jet needle height slightly, in order to allow performance tuning modifications when the stock intake or exhaust system has been modified. Tuning washers fit on top of the plastic needle cap and underneath the needle cap clip. Each washer is .025mm thick, and multiple washers can be used to provide the proper tuning desired. Fits all XJ550, 650 Turbo, XJ700-X, XJ750-X, XJ900RK, and XJ1100 models.

    MIKUNI MAIN JET NOZZLE OR EMULSION TUBE:

    Called by a variety of names, the main fuel jet tube is technically known as the MAIN NOZZLE, although they also go by the name of "power valves", "emulsion tubes", or some choice four-letter words whie you are trying to remove them from their bore hole in the carb body! These 2-3" long tubes have a series of very precise, very small holes that actually pass the fuel from the main fuel jet around the jet needle, and are what provide the final, precise metering of the fuel mixture through the main jet.

    Commonly clogged and dirty-filthy beyond belief, they are easy to damage while removing them or during the cleaner process. If the holes are enlarged, or the threads in the jet end damaged, these nozzles should be replaced, or your bike will never run properly.

    Okay, everyone asks, so here goes: should you use the OEM Yamaha or the aftermarket bowl gaskets? Well, the OEM Yamaha gaskets look and feel more substantial, and have a somewhat waxy coating to them, which is there for a reason I suppose---probably has to do with the longevity of the gasket when the float bowls are being removed and replaced quite often. HOWEVER, I've used both the OEM and the replacement bowl gaskets on my own bikes and carb sets and have never had either style leak. I make more money selling the aftermarket gaskets, but for the small difference in price, if you're not on an ultra-tight budget, I'd use the OEM gaskets on my own personal bikes..........just my thoughts.

    ALSO: if you use any type of sealant on these gaskets, use it on the BOWL side of the gasket (something like Permatex Copper Spray-A-Gasket is a fine choice). On the carb body side of the gasket, use a light oil....like Marvel Mystery Oil or the like....and barely moisten the gasket surface. This will allow the new gasket to soften slightly and allows the gasket to form itself to the raised mounting ridge that is cast onto the carb body mating flange.....and also allows for an easy, no-stick removal of the float bowl in the future!




    MIKUNI CARB FLOATS AND FLOAT NEEDLE VALVES:

    fs4) Aftermarket Mikuni float valve NEEDLE ONLY...for those who wish to do an extreme-budget rebuild, you can buy the rubber-tipped float valve needle by itself (without its brass seat).

    For use on all XJ550 models, all XJ700-X and XJ750-X models, all XJ900RK models with the clipped-to-the-float style seat, and all XJ1100 models:

    kk) OEM and Aftermarket Mikuni FLOAT NEEDLE VALVE ASSEMBLY---contains the float needle with retainer clip (if used), float valve brass seat, the seat o-ring, and the seat filter screen.

    NOTE: XJ900RK models can use either a valve with a 2.0mm seat opening and which uses a non-clipped-to-the-float needle style, or they can use a valve with a larger 2.3mm seat opening and which uses a clipped-to-the-float style of needle. THE TWO STYLES ARE NOT INTERCHANGEABLE---you cannot use one style seat with the other style needle. You CAN, however, interchange the complete needle/seat units on all XJ900RK (Mikuni BS33 series) carbs. However, you should use all four of the same style in a complete set of carbs. Generally speaking, we've seen the non-clipped needle and seat style valves (with the 2.0mm valve seat orifice) used mostly on North American models, and the clipped needle and seat style valves (with the 2.3mm valve seat orifice) used on the non-North American models.

    bb3) HCP8540 Aftermarket carb diaphram rubber RnR FLUID. Dissolved and chlorinated paraffin wax is the best (and perhaps the only) way to safely bring some life back into stiff, worn rubber material... such as that found in those all-important carb piston diaphrams. Years of hard life inside of your carb take their toll, and whenever your carb is apart for service, and generous application of this product will help to clean, maintain, and restore the flexibility, while prolonging their usable service life. 10cc dripper bottle contains enough fluid to do about eight diaphrams. Simple to use, spread on, wait a few seconds, wipe off, repeat and you're done!

    MIKUNI CARB FUEL SUPPLY AND BOWL OVERFLOW T-FITTINGS, CONNECTOR TUBES, AND O-RINGS:


    mtz1) OEM Mikuni fuel inlet T-FITTING AND CONNECTOR SUPPLY TUBES. The swivelling plastic t-fitting is used as the intake port from the petcock and "splits" the fuel flow to the left and right sides of the carb banks, while the aluminum fuel connector pipes are used to connect the outer carbs to the center carbs for incoming fuel supply. The inlet T-fitting was plastic, and was equipped with built in anti-leak "ribs" where they enter the carb bodies, while the aluminum connector tubes use separate o-rings (listed further below) to provide a leak-proof connection into the carb bodies.

    HCP5166 OEM plastic fuel inlet T-FITTING, use 1 on all XJ550 models in-between the #2 and #3 carbs.
    $ 30.00

    HCP9865 OEM plastic fuel inlet T-FITTING, use 1 on all XJ550 models in-between the #2 and #3 carbs.
    $ 32.00




    HCP5165 OEM aluminum fuel SUPPLY TUBE, use 1 each on all XJ550 models in-between the #1/2 and the #3/4 carbs. Each:
    $ 22.50

    HCP5239 OEM aluminum fuel SUPPLY TUBE, use 1 each on all XJ650 Turbo and all XJ700-X models in-between the #1/2 and the #3/4 carbs, and 1 on XJ900RK models between the #2/3 carbs. Each:
    $ 21.95



    HCP9866 OEM fuel bowl vent/overflow plastic T-FITTING, use 1 each on all XJ700-X models in-between the #1/2 and #3/4 carbs.
    $ 17.95

    HCP9867 OEM fuel bowl vent/overflow plastic T-FITTING, use 1 each on all XJ900RK models in-between the #1/2 and #3/4 carbs.
    $ 17.95


    HCP9864 OEM fuel bowl vent/overflow aluminum CONNECTOR TUBE, use 1 each on all XJ650 Turbo models in-between the #2/3 carbs. Each:
    $ 19.95



    mmm1) OEM and aftermarket Mikuni fuel rail connector pipe O-RING.....all fours carbs share a common fuel supply, and this fuel supply is distributed to each carb via either plastic, brass or aluminum tubes and T-fittings that connects one carb to another. These tubes fits into a machined bores in the carb base, and the tubes are sealed in their bores with these rubber o-rings. Additionally, XJ650 Turbo and XJ700-X and XJ750-X models also used bowl vent connectors (plastic T-fittings) that also used o-rings. NOTE: original seals were "D-rings" rather than "O-rings", but are now serviced only as o-rings, but are the correct shape and firmness to provide a leak-proof fit. You will only be able to access these seals if you break the carbs out of their rack! (and if you do break the rack, you need to replace these seals).

    NOTE: on all Mikuni model carbs, the factory parts diagram show the use of a plastic, ribbed fuel inlet T-fitting that does NOT use any o-rings.....the molded in "ribs" are supposed to take the place of o-rings for sealing the t-fitting to the carb body. To be honest, like many of you have commented, I don't understand either how the ribs on the plastic fitting by themselves could have maintained an effective seal, but......I'm not fuel line engineer! You can always add an extra two o-rings to this t-fitting to provide a more secure connection.


    - Use 4 seals per fuel connector pipe in-between carbs 1&2 and 3&4, or a total of 8 seals per entire carb rack, for Mikuni carbs used on all XJ550 models. NOTE: the plastic fuel inlet "T" fitting does not use o-rings.

    - Use 4 seals per fuel connector pipe in-between carbs 1&2 and 3&4, and use 4 seals per bowl overflow connector pipes, for a total of 20 seals per entire carb rack, on the Mikuni carbs used on all XJ650 Turbo models. NOTE: the plastic fuel inlet "T" fitting does not use o-rings.

    - Use 4 seals per fuel connector pipe in-between carbs 1 & 2 and in-between 3 & 4, and use 2 seals on each bowl overflow "T" connector pipes, or a total of 12 seals per entire carb rack, for Mikuni carbs used on all XJ700-X and XJ750-X models. NOTE: the plastic fuel inlet "T" fitting does not use o-rings, and the bowl overflow plastic T-connectors actually use a slightly larger o-ring. However, these o-rings will fit the bowl-overflow T-fittings, although they will result in a slightly more loose fitting pipe in the carb bores. Since these bowl overflow T-connectors don't actually carry fluid---they normally just vent fuel vapors---the slightly looser fitment is not an issue.

    - In case you're wondering, XJ1100 models used two plastic T-fittings for fuel inlet supply, and those fittings do NOT use any o-rings. There are no bowl vent connector tubes on 1100's, so there are no o-rings used at all on 1100 models!

    Woah. OK, so i just began tearing into my carbs (repair manual in hand) and it looks like i have my work cut out for me. After sitting for several years I have a lot of stuck screws. Many of which are going to be mangled beyond recognition. I will have to get it all apart and then make a list of replacement parts. Looks like I'm not going to get off easy though.
    Thanks a bunch for the list Chacal. I will definitely be in touch.

    Hey Dawg, just give me a holler when you're ready. And trust me, doing a complete and thorough job is actually the true meaning of "getting off easy"!

    Hey Iron, I think you'll find that any set of carbs that have been setting around for a bit are going to be as your described. The 650 Turbo carbs are unique to that model, so they're kinda hard to find. Luckily, most of the replacable items ARE available, so it really comes down to complete dis-assembly and thorough cleaning of every last part......time consuming but not rocket science. You can even soda-blast the bodies to clean up the aluminum corrosion and make those bright and shiny-new looking. Other than that, the rest of it is straight rebuild parts and procedures.......

    Hey Iron, unfortunately, for the Turbo carbs there is no pre-assembled rebuild kit...........

    Iron,
    Check out A&J Cycle Salvage out of philadelphia. If you can't find a set of those carbs on eBay then A&J would be your next best bet. Just google them and go to thier site and email them what you need. Hope this was helpful.

    @chacal Are these parts still available, as I see the list is posted 12 years ago?
