    EXHAUST SYSTEM OVERVIEW:

    As with many other systems on these bikes, the Yamaha XJ-series of exhaust systems are a mini marvel-to-behold, well thought out and engineered......so please do keep this in mind when considering aftermarket "performance" exhaust systems.

    Let's start with the headpipes: many of them are actually of a double-wall design......an inner tube (that carries that gas) and an outer tube that can stay relatively cooler and thus maintains its chromed appearance much better and longer (this is why the chrome doesn't turn "blue"quickly, as it does with aftermarket, single-wall header pipes) . Additionally, they are tuned in their internal (gas-carrying) pipe diameter to match the flow characteristics needed for their intended use.....thus, for example, even though the headpipes for an XJ650RJ Seca can physically be installed onto an XJ700 engine, the inner pipe diameters do differ, and thus the swap may cause more harm than good, as it messes up with the balance of airflow thru the engine.

    Pipe diameter helps determines (among other things) both the volume of exhaust gas that can be carried away, and, equally as important, the speed at which those gases will flow thru the pipe. All other things being equal, a bigger diameter pipe --- while surely capable of flowing more gas volume --- will also slow down the progress of gas thru that pipe......which, in the world of exhaust gas flow --- and its important effects on intake gas flow (how well each cylinder can be scavenged of its burnt exhaust gases and allow for a full and complete incoming fuel/air charge) --- is a mighty important consideration.

    http://www.gomog.com/allmorgan/exhaustbackpressure.html


    By the way......although we've touched on some of the reasons above.....in regards to "swapping" headpipes between models, our best advice is: don't. Besides the whole "gas capacity and velocity" issues discussed above, there also the issue of fit: although the headpipes between a 550 and a 750 (for example) may look the same, and may actually bolt onto the cylinders heads, both their length and their unique bend angles ---- needed to follow the frame and mate up with the exhaust collector ---- will likely be different.


    Next: the collector. Although these weren't used on the XJ650 Maxim and XJ1100 models --- those bikes use a crossover pipe to perform the same function --- the collector box performs a few not-so-obvious but very important functions, and does it in a very admirable manner. First, of course, it provides a transition between the headpipes and the mufflers. Second, it keeps the decibel levels down to a reasonable volume. And finally....and very important for overall engine performance.....it provides a method of assisting that all-important "gas velocity" by providing a sufficient volume of space for "warehousing" (temporarily) the exhaust gas volume, while also providing (via its unique design) the ability to assist in providing maximal exhaust gas flow.

    If you've ever looked carefully at your heavy (and probably-rusty) collector, you'll notice that it is designed ("split") in such a way so that cylinders 1 & 4 (the outer two) "share" a certain internal cavity space, while cylinders 2 & 3 "share" the rest of it. This is important because of the firing order of your engine: 1-2-4-3

    If cylinders #1 and 2 --- which fire sequentially (and, thus need to exhaust their spent gases sequentially) ---- were to share the same exhaust cavity, then their (sequential) exhaust gas flows would be "spaced" too close to each other (in time) and would see vastly different back-pressures (cylinder 2, which fires after cylinder 1, would see more back-pressure than cylinder 1, which emptied itself into a, well, into an "empty" exhaust collector).

    To put it another way, cylinder #2 sees a lot more back-pressure than cylinder #1, because the gas pulse from #1 doesn't have much time to exit the system before the pulse from #2 is trying to squeeze itself in the same pipe. Notice that cylinders #3 and 4 have a similar situation.

    The same thought goes for the other two cylinders (# 2 and 3). Notice how even the aftermarket "dual" exhaust systems suffer from the above problem, since they are really two separate system, one system being for cylinders #1 and 2 (left side) and the other being for #3 and 4. Notice how it's the "sequential" problem.....since cylinders 1 and 2 fire (and exhaust themselves) sequentially, and since those gases vent into one common chamber, that cylinder #2 is going to see more backpressure than cylinder #1 will......and same for #3 and 4.

    This un-balanced situation....with different cylinders seeing different exhaust system back-pressures......can (and does) result in different amounts of burnt gas scavenging from the differing cylinders, which is not the way to get an engine to make the most amount of power.


    Aftermarket 4-into-1 systems overcome this "differential scavenging" situation by re-introducing, somewhat, a "collector".......where the fours pipes come together into a common chamber, just before the muffler. This collector allows the system to maintain some amount of equalized back-pressure (and thus burnt gas scavenging), while the particular placement of the four headpipes, as they come into the collector, allows a little bit of "pull-thru" between each cylinder, helping to reduce overall system back-pressure levels, while still maintaining a somewhat equal amount of back-pressure to each cylinder.

    Or, maybe, aftermarket systems do no such thing:

    http://www.motorcycleproject.com/text/exhausts2.html


    Of course, the final piece of the puzzle is the mufflers, which are primarily decorative pieces....they look nice, stylish to the lines of the bike, contribute almost no back pressure to the system, and provide a nice throaty (but not too loud or droning or buzzing) sound output.


    So just remember that the real heavy-lifting in the exhaust system is actually done by the headpipes and the unique, well-designed (but often overlooked) collector box.



    EXHAUST HEADPIPES:

    Exhaust Pipe Wrap:

    So, if you're headpipes are all rusty and crusty and basically socially unacceptable to be seen out in public with, but you don't want to string for the expense of new, used, or re-chromed replacement pipes, well then there's always the handy RACER'S EXHAUST WRAP TAPE. Tough, durable, fiberglass cloth wrap withstands heat up to 2000-F, and also looks great on those "old-skool" resto projects.

    These wraps come in either 1" or 2" wide versions, in both a jet-black or a tan (off-white) color. Well, you'll have to measure the diameter of your header pipes to tell for sure! But with the "typical" diameter of 1-1/2", and with a wrap technique that overlaps about 1/2", you'll need about 25' of roll length of the 2" wide wrap to do four header pipes, and slightly more when using the skinnier 1" wide wrap material.

    Of course, the 1" wide wrap will allow you to create a tighter, more closely-spaced wrap appearance, while the 2" wide material gives you those big, wide-open-spaces look..........

    To finish up your wrap, you'll need some stainless steel WRAP BAND-TIES" to terminate each end of the wrap.....so two of those per header pipe, total of 8 per bike.

    NOTE: since the wrap is made from specially constructed version of fiberglass, it is ever-so-strongly recommended that you wear our fabric or rubber work gloves, a long sleeve shirt and long pants, and eye protection when installing this wrap.....or you'll be itching for days!!

    Exhaust Pipe Polish:

    Well, suppose your exhaust pipes aren't rusty and cruddy, but they've turned blue or otherwise dis-colored? Well, the world-famous "blue-away" CHROME POLISH is what you'll need, as its specially formulated to remove the bluish haze from chromed and stainless steel. NOTE: our experience shows if the chrome has been discolored beyond "blue" to an almost black-ish - grey color, then this product (nor any other that we know of) will remove such discoloration.

    It is recommended that our metal sealer HCP10640 be applied after polishing to protect and seal the finish.



    HCP8236 Aftermarket Blue-Away CHROME POLISH, comes in a 2.5 ounce tube, a little bit goes a long way! NOTE: this product can only be shipped via ground transportation and cannot be shipped outside of the continental USA.
    $ 16.00

    HCP10641 Aftermarket metal POLISH and SEALER, comes in a 3.5 ounce tube. While this product is also a polish----like the Blue-Away above---it is not specially formulated to remove the high-temp "bluing" that occurs. However, it does leave a hard, corrosion-resistant finish on aluminum, chromed, and stainless steel (and is very well suited for use as a polish on those materials), we also recommend it merely for its protective qualities when using the HCP8236 polish on exhaust systems.

    HCP2611 OEM exhaust header pipes COLLECTOR BOX, 4 header pipes come in, two muffler connector pipes go out. Comes complete with the outer side chrome covers, for all XJ750 Seca models.

    EXHAUST SYSTEM GASKETS:

    Exhaust system joints and their gaskets take a pounding, get old and compressed, and then leak.....and sometimes, those leaks can sound exactly like the sound that an engine makes when it's on the verge of self-destruction!

    To check for exhaust leaks, take a small stick, pencil, etc. and scotch tape a small section of toilet tissue to it, so you have a "flag" of sorts. Then hold it up around each exhaust joint, and if there's a leak, the flag will blow wildly around, letting you know about the source of the leak and the dreadful sound that you've been hearing........

    NOTE: all of the gaskets listed in this section are verified to only fit stock, factory original exhaust systems only! We have no knowledge or experience with any of these items fitting any aftermarket exhaust systems.

    All factory exhaust system components use sleeve gaskets at every exhaust joint (header-to-collector, collector-to-muffler can). Most of the gaskets are different sizes for different engines, as different engines used different sized header pipes, collector boxes, and of course mufflers (and by "size" we mean the outer diameter of the junction point, not the just the shape or style of the item).


    Exhaust System Interchange: generally, no, you can't, as the different components will not interchange, mainly due to:

    a) header pipes: the length, bend angle, and how far back/at what angle the pipes enter the collector box. Header pipes generally follow the lines of the front of the frame of the bike, and are designed to plug into the collector box at a certain angle.

    b) collector boxes are designed to accept and then exit into the mufflers at a certain angle and point, and two collectors boxes that may be the same length may have differing angles of entry and exit designed for different bikes.

    c) muffler cans..........besides differing inlet tube diameters, some mufflers are "kinked" or bent about 6-8" behind where they exit the collector box, whereas others are straight as an arrow, designed so that they can follow the lines of the bike correctly. Other models (XJ650, XJ1100) do away with the collector box entirely, and the muffler is integrated into the "collector" that accepts the header pipe outlets.

    On other models, the mounting point for hanging the muffler will differ in placement even upon mufflers which might otherwise "fit" and interchange properly.



    Cylinder Head Exhaust Port Gaskets:

    a9) OEM and aftermarket cylinder head EXHAUST PORT RING GASKET....these thin "doughnut" ring gasket between the cylinder head and the exhaust header pipe. A very common source of leaks. You should ALWAYS replace these gaskets whenever you remove your exhaust header(s). Aftermarket versions fit and seal just like the originals.

    A good visual on the procedure involved to remove and replace these gaskets can be seen at:

    http://xjbikes.com/forums/index.php?threads/29356


    NOTE: it may be necessary to use 2 of the exhaust port gaskets (instead of 1) per port when using aftermarket exhaust systems (MAC, Kerker, etc.) to achieve a leak-proof fit, and it is recommended that the OEM gaskets be used for such applications.

    HCP24266G Aftermarket exhaust system TURBO WASTEGATE OUTLET-to-RIGHT MUFFLER JOINT PIPE INLET GASKET. The round gasket is made of an aramid graphite material and does not feature the original metal “fire ring” around the central hole as original. Aramid graphite is a strong, high-temp material and is a good, less-expensive substitute material to use for this application, as this right side portion of the exhaust system is only active during pressure pops when the wastegate is activated (to bleed off excess pressures). Of course, if you’re redlining in every gear and/or have a modified wastegate - boost controller system that regularly is going to run up to really high system pressures, then we recommend the original metal style gasket (HCP24266M) above to prevent blowing out this graphite gasket (this graphite material is not nearly as resistant to high pressures as the original style metal gasket is) Use 1 per engine on all XJ650 Turbo models. Each:
    $ 11.95

    EXHAUST:

    --Hardware.


    EXHAUST SYSTEM HARDWARE:

    eh5) Original and aftermarket EXHAUST SYSTEM HARDWARE perfectly replaces the stripped, damaged, rusted or missing originals. It is always a great idea to replace these hardware items whenever you have your system apart. And as usual, ALWAYS use anti-seize compound on the threads of any exhaust system fastener during assembly!

    Exhaust system hardware is listed below BY MODEL. Within each model listing, the hardware products list starts at the "beginning" of the exhaust system---meaning where the header pipes attach to the cylinder head exhaust port----and then proceed from there, more-or-less in the following order (some models vary slightly in their layout and orientation):

    * the cylinder head THREADED STUDS, their special FLANGED NUTS, and the large finned, cast aluminum RING NUT---which of course really isn't a nut at all! By the way, I can't stress just how great an idea it is to replace the flange nuts whenever you remove your originals, for whatever reason.

    * the header pipe exhaust gas analysis test port BOLT and its WASHER.

    * the joint where the header pipe outlet fits into the collector box inlet. On most models, the pinch clamp at this joint is permanently attached to the collector box inlet, and the only replaceable items are the pinch clamp BOLT and WASHER. The XJ1100 models are the only ones that use a replaceable PINCH CLAMP.

    Please note that we do offer replacement, chrome-plated single-bolt PINCH CLAMPS that can be used to replace damaged or rusty originals on most other models; however, since the original pinch clamps are spot-welded onto the collector inlet pipes, you will have to carefully cut away or break the spot weld in order to replace them. The replacement clamps will fit and seal like the originals, but do not have the outer edge flanges as original clamps did (but this will not affect their ability to seal properly). Each replacement pinch clamp come complete with a bolt, washer, and nut.

    * the collector box attaching hardware needed to secure the collector box---and by design, to also support the weight of almost the entire exhaust system----to the frame. Varies by model, but usually consists of a Bolt that goes through the collector box, which is then insulated by a rubber INSULATOR, and which attaches via a COLLAR to a "u"-shaped metal BRACKET. This Bracket is then attached to the bike frame via two BOLTS and WASHERS.

    It should be noted that worn insulators (dampers) in this part of your exhaust system can lead to excessive vibration (buzzing) in the system, and it is recommended that you periodically inspect them for integrity and the mounting hardware in this critical area for security and correct tightness.

    Also, note that XJ650 Maxim and Midnight Maxim models, as well as XJ1100 models, do not use a "collector box" and thus there is no associated exhaust system-to-frame mounting hardware, brackets, etc. on those models.

    * the joint where the collector box outlet (or equivalent) fits into the muffler inlet stub pipe. On most models, the PINCH CLAMP at this joint is permanently attached to the muffler inlet stub pipe, and the only replaceable items are the pinch clamp BOLT and WASHER. XJ1100 models are the only ones that use replaceable PINCH CLAMPS, in addition to the fasteners.

    Please note that we do offer replacement, chrome-plated single-bolt PINCH CLAMPS that can be used to replace damaged or rusty originals on most other models; however, since the original pinch clamps are spot-welded onto the collector outlet (or muffler inlet) pipes, you will have to carefully cut away or break the spot weld in order to replace them. The replacement clamps will fit and seal like the originals, but do not have the outer edge flanges as original clamps did (but this will not affect their ability to seal properly). Each replacement pinch clamp come complete with a bolt, washer, and nut.

    * finally, our tour ends at the muffler bracket-to-footrest bracket (or frame) mounting BOLT, WASHER, and NUTS, as well as the rubber BUMPER that is mounted on the left muffler can to cushion against the centerstand while it is in the "up" position.


    NOTE: the torque specification is 7.5 foot-pounds for the exhaust header pipe-to-cylinder head stud flange nut.

    NOTE: for all XJ550 and XJ650 models, the HCP577 exhaust header pipe Ring Nut is a bright, semi-polished natural aluminum, while the HCP578 Ring Nut is black-plated. Since both ring nuts share all the same critical dimensions, the black HCP578 ring nut can be used in place of the natural-finish HCP577 ring nut on all engines for a more aggressive appearance.

    NOTE: all of the hardware listed in this section are verified to only fit stock, factory original exhaust systems only! We have no knowledge or experience with any of these items fitting any aftermarket exhaust systems.


    NOTE: if the threaded holes in the exhaust system clamps or pipes have minor damage or rust damage, they can usually be easily salvaged with a thread-chaser/tap:

    TURBOCHARGERS:

    If your turbo isn't happy, then nobody's happy. Given the stress and operating conditions that these little puffers operate within, it's a wonder that they last as long as they do.

    We stock freshly rebuilt stock Mitsubishi TC03A original turbo units, available as both stock and performance-upgraded versions that allows you a simple, bolt-on solution to your turbo woes.

    NOTES:

    - all rebuilt turbocharger units are sold on a trade-in basis, with a refundable core charge fee applied (which will be fully refunded upon the return of a stock, factory, complete, un-damaged turbo unit). Rebuilt turbo units carry a 1-year (from date of purchase) warranty against defects in workmanship and materials only, subject to inspection and analysis of any failed unit.

    - these rebuilds are for "street" bikes, and not for drag or road-race use. Performance-upgrade units feature a slightly larger, more efficient compressor wheel, and/or a ceramic-coated turbine housing (the retention of as much exhaust heat as possible is the key to extracting more efficiency from your turbo).

    - all units should be used with the factory wastegate-control vacuum actuator. For even greater control and performance enhancement, use the HCP17910 or HCP17911 BOOST CONTROLLER module.....it's easy to install, tune, and tailor to your unique riding conditions and style!

    - a great review of some of the operating characteristics and problems inherent to the Yamaha XJ650 Turbo bikes can be reviewed at:

    http://www.turbomotorcycles.org/TMIOA/TechHelp_Yamaha.html


    A common problem with the turbo units on this bike is the small pressure relief valve situated at the front of the engine, just off to the left side of the oil filter element boss (on the crankcase). This spring-loaded "ball bearing" check valve is supposed to prevent oil supply to the turbocharger when the engine is off. If this check valve fails into the "always off" position (eliminating or reducing oil supply to the turbo), you'll burn up the turbo bearings mighty quick (like within a minute or two of operation). If the check valve fails in the "always open" position, it will allow a continual supply of oil to the turbo (even when the engine is off) and can result in a significant puddle of oil under the turbo unit (failure of the copper crush washers at the turbo oil supply inlet pipe can also cause this issue, but typically this type of failure will result in only small drops of oil under the turbo, whether then engine is running or not).

    If these situations are detected, the pressure relief valve must be serviced (no replacement is available) and be internally cleaned out of gunk, grime, crud, crap, and what-not. It's kind of a bear to get to, and may require exhaust system removal, but it is an important part of regular turbo system maintenance:

    Stock Rebuilt Turbocharger:

    These units will provide the same level of performance and boost as the factory-equipped turbo unit, whether used in the stock 1982 configuration or with the 1983 version with the "Power-Up" boost enhancement kit. Note that neither the EXHAUST MANIFOLD nor the wastegate VACUUM ACTUATOR UNIT are not included with any of the turbocharger units and should be ordered separate if needed.

    HCP17822 Rebuilt OEM TURBOCHARGER. Stock rebuild perfectly replaces your worn out or leaking original unit. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
    $ 795.00 + refundable $ 300.00 core charge.

    HCP18165 Rebuilt OEM TURBOCHARGER. Enhanced stock rebuild perfectly replaces your worn out or leaking original unit. On this version, the turbine (exhaust) housing has been ceramic-coated to help retain as much heat as possible, thus increasing the turbo efficiency, reducing lag times and creating full boost at a lowered rpm. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
    $ discontinued



    Upgraded Rebuilt Turbocharger:

    These units will provide an increased level of performance and boost as compared to the factory-equipped turbo unit, whether used in the stock 1982 configuration or with the 1983 version with the "Power-Up" kit. A slightly larger, more efficient compressor wheel results in less turbo lag, and quicker spool-up, resulting in more boost at any given rpm's up to the maximum pressure.

    It is strongly recommended that the aftermarket BOOST CONTROLLER module be used in conjunction with either of these upgraded turbochargers to allow the ultimate in performance. Your carb fuel circuits will almost always need to be enriched by 2-4 jet sizes over stock.

    Note that neither the EXHAUST MANIFOLD nor the wastegate VACUUM ACTUATOR UNIT are not included with any of the turbocharger units and should be ordered separate if needed.


    HCP17823 Rebuilt OEM UPGRADED TURBOCHARGER. Performance rebuild perfectly replaces your worn out or leaking original unit. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.
    $ 995.00 + refundable $ 300.00 core charge.

    HCP17913 Rebuilt OEM UPGRADED TURBOCHARGER. Enhanced performance rebuild perfectly replaces your worn out or leaking original unit. On this version, the turbine (exhaust) housing has been ceramic-coated to help retain as much heat as possible, thus increasing the turbo efficiency, reducing lag times and creating full boost at a lowered rpm. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.

    Upgraded Stock Exhaust Manifold:

    As we mentioned before, one of the key ways to boost the efficiency (and thus performance) of your turbo is to capture and retain the heat energy in the exhaust system............after all, that's the whole point of a turbocharger, to take the "wasted heat" content of the exhaust gas stream and make it do something useful (turn a turbine wheel which can then be used to compress the intake flow thru the carbs and into the cylinders). Thus you want to "capture and retain" as much of that exhaust system heat as is possible.

    These ceramic-coated EXHAUST COLLECTOR MANIFOLDS are the perfect way to accomplish this heat retention. These are original factory manifolds that have been inspected, cleaned, and then ceramic-coated with a durable, satin-grey finish.

    NOTE: all upgraded exhaust manifolds are sold on a trade-in basis, with a refundable core charge fee applied (which will be fully refunded upon the return of a stock, factory, complete, un-damaged exhaust manifold).


    HCP17915 Rebuilt OEM CERAMIC-COATED EXHAUST MANIFOLD. Enhanced performance stock exhaust manifold which has been ceramic-coated to help retain as much heat as possible, thus increasing the turbo efficiency, reducing lag times and creating full boost at a lowered rpm. NOTE: a refundable core charge will be applied to this part, and requires the delivery to us of an original stock, complete, un-damaged turbo unit.

    TURBOCHARGER REPAIR AND SERVICE PARTS:

    Well, there's nothing like a little tiny huffer to make an engine scream, and Yamaha was one of the first and most successful at that game with the introduction of their XJ650 Turbo Seca model in 1982. And not wanting to rest on their past achievements, for 1983 they upgraded the turbo system to allow the creation of 12 psi of boost pressure (up from 7 psi on the 1982 models), and even offered a Power-Up Kit package to all 1982 owners to upgrade their turbo system to the higher boost pressure created by the more powerful 1983 models.

    We've got the proper TURBO REBUILD PARTS needed to replace or repair the various turbocharger components. Please note that the oil supply and oil scavenge line parts are located in other sections of the catalog.

    NOTE: it is imperative that the turbo wheel/shaft assembly be re-balanced after a rebuild or catastrophic turbocharger failure may occur!



    Turbocharger Rebuild Kits:

    tc1) Aftermarket turbocharger REBUILD KITS contain all the necessary parts to properly rebuild an original turbo to stock specifications. NOTE: turbine and compressor wheels, housings, and some other components are not available. Only the standard replaceable "wear" parts are included in the rebuild kits.

    Turbochargers are hardy little items, but do require periodic rebuilds. The shafts and vanes must be balanced as a unit. If you are unable to perform this service, we suggest that you have the turbo rebuild by a shop experienced in performing such work or purchase one of our fully rebuilt turbo units.


    HCP24159 Aftermarket TURBO BASIC REBUILD KIT contains all of the typical "wear" items that will be needed to refresh a factory turbocharger. Includes the pistons rings (2), shaft bearing/oil valve, thrust bearing, thrust collar, seal plate, seal plate o-ring, compressor housing o-ring, shaft locknut, and the oil line gasket.

    TURBO OIL SYSTEM:

    The oil pressure and return lines for the turbocharger endure an amazing amount of heat, and as such, are likely to suffer from deterioration and failure. The turbo unit uses a "floating" bearing design that allows the impeller to spin up to----get this!----220,000 rpm's, and it's life depend entirely upon its bearing getting enough oil to properly "float". This requires adequate volume and pressure of oil......so leaks anywhere in this system are frowned upon in a very critical manner. Below is a selection of the proper O-RINGS, GASKETS, and HARDWARE pieces necessary to insure all is well with these crucial lines.

    The parts list below starts at the "beginning" of the oil flow, at the oil filter housing, and works its way through until the end, where the return line terminates at the scavenge pump.

    $ 24.95

    HCP24266G Aftermarket exhaust system TURBO WASTEGATE OUTLET-to-RIGHT MUFFLER JOINT PIPE INLET GASKET. The round gasket is made of an aramid graphite material and does not feature the original metal “fire ring” around the central hole as original. Aramid graphite is a strong, high-temp material and is a good, less-expensive substitute material to use for this application, as this right side portion of the exhaust system is only active during pressure pops when the wastegate is activated (to bleed off excess pressures). Of course, if you’re redlining in every gear and/or have a modified wastegate - boost controller system that regularly is going to run up to really high system pressures, then we recommend the original metal style gasket (HCP24266M) above to prevent blowing out this graphite gasket (this graphite material is not nearly as resistant to high pressures as the original style metal gasket is) Use 1 per engine on all XJ650 Turbo models. Each:

    Turbocharger Vacuum Boost Controller:

    Get the maximum control and power out of your turbo system with the use of an easy-to-install, compact BOOST CONTROLLER MODULE. About the size of a pack of cigarettes (about 2-1/2" long x 3/4" thick), these "dial-a-boost" units manage the opening rate and timing of the wastegate operation, thus allowing you to tune the boost response of your system to operating and environmental condition.

    Here is some good information about the Yamaha turbo system, including the pop-off valve settings, the factory "power-up" kit, and using an aftermarket boost controller:

    http://www.xjbikes.com/forums/threads/turbo-seca-dyno-results.35049/page-2


    NOTE: the use of a wide-band O2 sensor is recommended when tuning for maximum power output of any turbo system, but especially with the use of a boost controller.

    EXHAUST SYSTEM TOOLS:

    NOTE: SOME OF THE FOLLOWING TOOLS ARE AVAILABLE FOR RENTAL!!: some tools are a one-time or infrequent use tool, so it may be more economical for you to rent them from us, rather than to purchase outright. Please see the “rental” section within the THE TOOLBOX section of our catalog at:

    http://xjbikes.com/forums/index.php?threads/xj-parts-catalog-section-p-the-toolbox.44630

    and review the availability and procedures in the TOOL RENTAL section.


    Prevent any of the above situations from happening to you by using one of our anti-seize products when installing your new bolts!


    it54) Aftermarket broken stud EXTRACTOR TOOL KIT. Common problem: you snap or shear off the head of a fastener, now what do you do? Prevent these situations from happening to you by using one of our anti-seize products when installing new bolts or studs!


    HCP10302 Aftermarket 6mm BROKEN STUD EXTRACTOR......this is the correct size for both the exhaust headpipe studs and the intake manifold bolts in the cylinder head, which are the most common fasteners that you'll need to use these extractor tools on. You simply pound this extractor onto the stud, and then use an open-end wrench to twist it out. As long as you have a bit of the broken stud remaining outside of the cylinder head threaded hole (in other words, the fastener has not broken off "flush"), then this tool is what's going to save your day. Similar in concept to a "ez-out", but these tools have their "biting" surfaces on the inside of a socket-type housing, so that the hardened steel ridges bite into the stud and allow you to extract it. Also works great on screw or bolt heads that have had the drive slot ruined or the bolt head rounded off.
    $ 69.95

    HCP26979 Aftermarket complete STUD EXTRACTOR and INSTALLATION TOOLS SET. Complete set of 3 different size tools, these are an upgraded version of the “two locking nuts” method of stud extraction or installation, and their small size allows them to work easily in cramped spaces. Note that this type of tool requires that you have decent threads on the end of the stud: www.youtube.com/watch?v=NNH7u87dhng This set has the proper sized tools to install and remove exhaust manifold studs, cylinder head and cylinder jug studs, the long cylinder head-to-crankcase studs (all models except XJ700-X and XJ750-X engines), broken intake manifold bolts and many other threaded studs (or headless bolts) on the engine and drivetrain. Contains one each M6 x 1.00 pitch, M8 x 1.25 pitch, and a M10 x 1.25 pitch tool.
    $ 29.95

    HCP10301 Aftermarket complete STUD EXTRACTOR TOOLS SET. Complete set of 4 different size extractors, and these can be used with ratchet wrenches for ease of removal. These are “roller clutch” type removers that use internally locking rollers to grip and turn the stud. This type tool will damage the threads as part of the removal process, and although it’s possible to use them on broken threads (the smooth shank portion of the stud, even if that is all that is present i.e. the stud or bolt has snapped off and all that remains is the unthreaded portion), they don’t always work all that well on smooth surfaces…..but this also means that the can also be used on dowel pins and some guide collars. Note that these stud removers are much larger is physical size that the HCP26979 tools, which may present problems in restricted areas: www.youtube.com/watch?v=aE5VnScjRcI This set has the proper sized tools to remove exhaust manifold studs, broken intake manifold bolts, cylinder head and cylinder jug studs, the long cylinder head-to-crankcase studs (all models except XJ700-X and XJ750-X engines), and most other threaded studs (or headless bolts) on the engine and drivetrain. Contains one each of a 6mm and 8mm extractors (which can be used with 3/8" drive ratchets) and one each of a 10mm and 12mm extractors (which can be used with 1/2" drive ratchets). You simply pound the extractor onto the stud, and then use an appropriate sized ratchet wrench to twist it out. Comes in a molded storage case.

    c9a) THREAD CHASER TAPS and DIES. Over time, rust and it seizure effects can cause fastener threads to become pitted and result in sloppy fits and un-reliable torque readings……besides making assembly and dis-assembly a pain in the tailpipe and risky. Out line of THREAD CHASING TAPS (for threaded holes) and CHASER DIES (fot the bolt or screw fasteners) are used to clean, restore, and repair threads on the such items. These tools help restore that like-new feel to used fasteners and their accepting holes, and will straighten and restore threads to allow for proper torque settings to be achieved and maintained.

    Taps can be manipulated with a proper sized wrench on the square shank of the tap, or for more secure result, use our HCP28170 TAP HANDLE, featuring offset handles and fully adjustable head for all m3-m12 size taps. This is the proper way to hold a tap or extractor to insure that the force is directed straight down and doesn’t “wobble” as you are cutting, reaming, or extracting. Much better than using pliers or vise-grips to hold the tool……..

    And unlike standard round dies, ours feature cutting teeth within a standard “hex-nut” shape, so you can use a wrench or socket to hold the die and turn it over the fastener. Just like cleaning / chasing threaded holes with a tap, this task is easy to do, and when you’re done you’ll be glad you took the time to do the job properly!

    Always lubricate the tap or die tool (or fastener) with a light oil or grease during use, or use one of our specialty THREAD CUTTING FLUIDS listed further below.

    The following professional quality tool-steel metric cutting taps and dies will allow you to either "clean-up" or re-thread distorted or stripped threads in all metals, soft (aluminum) to hard (steel), and are a great addition to your toolbox.

    EXHAUST SYSTEM CHEMICALS:

    Assembly Chemicals:

    xx1) Fastener ANTI-SEIZE PASTE. Yeah, it's smelly and makes a silvery mess on your fingers, but this stuff is a life-saver for any true wrencher, because it prevents problems down the road. Use it on any metal fastener that does not require a "loctite" thread-locker material to be used. This means on just about every fastener that is carb, engine case, or suspension-related! (except for carb upper and lower rack-mount screws and butterfly valve screws, which do require the use of a thread-lock fluid). If you think that it might, sometime, in the future, need to come off: use anti-seize compound! NOTE: the "base" metal material used in the different anti-seize pastes below do not determine what type of fastener to use such pastes on; it merely signifies what base material is used to create the anti-seize paste. You can use any "based" anti-seize paste on any type of fastener and metal.

    NOTE: the use of anti-seize compounds will result in a TORQUE-MULTIPLYING EFFECT……..the result of a reduction in friction between the threaded contact points……and thus fasteners treated with anti-seize compound should have their torque values reduced by at least 10-15% when installed into steel material, and up to 25% into aluminum materials or other “soft” metals” (such as spark plugs into cylinder heads, or almost any other type of fastener into the engine) …… note that this rule applies only to service manual torque specifications on fasteners that are not indicated to be treated with anti-seize fluid by the factory …. if the factory manual specifies the use of an anti-seize coating, then the specified torque value for that fitting already takes into account the “reduced torque” necessary.

    Super-Penetrant Fluids and Lubricants:

    Sometimes, the toughest part of working on a vehicle is battling the effects of time: seized fasteners, caused by rust, corrosion, and other factors, turns what should be a 5-minute effort into a 50-minute (or more) chore, complete with rounded-off, ruined, or snapped fasteners, e-z outs, heli-coil inserts, and more.........and that's just not right.

    While the proper use of our various Anti-Seize products will prevent these nightmares from occurring in the future, you're stuck in the here-and-now, and the best way to handle these obstacles is to have the proper tools at the stand-by; and in the case of fastener seizure, the proper "tool" is a can or two of our SUPER PENETRATING LUBRICANTS at the ready; a couple of squirts, a little bit of time-----perhaps some heat for those really nasty situations----and you're on your way again, hopefully not too much worse for the experience.....

    Great for use on all fasteners, fork tube cap bolts, intake and exhaust manifolds bolts, studs, and nuts, lock cylinder tumblers, or anywhere an un-cooperative fastener can be found. Can even be used to help un-seize frozen engines!

    Be aware that these products are not your typical, garden-variety, run-of-the-mill "retail" type products; these are designed an used as industrial- and military-strength products, meaning they have special formulations that include a dollop more of the "good stuff" within them to solve the toughest seizure problems imaginable (the "good stuff" ingredients cost more, and it is those compounds that are left out of or reduced in concentration in "retail" level consumer products).

    NOTE: the following product(s) can only be shipped via ground transport (which thus eliminates the postal Priority Mail, postal Express Mail, or private carrier Expedited levels of service for this item) and cannot (and will not----don't even ask!) be shipped outside of the continental USA. Additionally, there may be a per-package weight or quantity restriction, and thus multiple-unit orders of this product may have to be shipped in separate packages and will incur additional shipping charges.


    HCP10331 Aftermarket standard-duty PENETRATING LUBRICANT, in a generous 16-ounce aerosol can.

This product is what we use and recommend for freeing stuck fork tube cap bolts and other such challenging fasteners.
    $ 24.95

    HCP11974 Aftermarket super-duty PENETRATING LUBRICANT, in a generous 13-ounce aerosol can. Same as our standard-duty formula above, but also includes graphite to not only enhance and speed up the penetrant action, but also gets down into the pores of the metal for the greatest possible lubrication possible. The cat's-meow of penetrating fluids, can even be used to un-seize frozen engines or as an engine assembly lube! This fluid is also a great choice for use as a drive cable lubricant.
    $ 26.95

    HCP10333 Aftermarket extreme-duty PENETRATING LUBRICANT, in a generous 16-ounce aerosol can. Same as our standard-duty formula above, but also includes liquid silicone to enhance and speed up the penetrant action. This product is also an exceptional choice for use as a control-cable lubricant.

    Rust Removal and Prevention Fluids:

    rr4) Concentrated RUST REMOVER magically dissolves rust on all iron-based metals. Spray or wipe directly onto rusty parts, or immerse the items in a container full of this solution (diluted), let it work, then rinse off. Highly concentrated, easy to use, leaves the metal surfaces grease-free and ready for further processing or finishing. GREAT FOR DE-RUSTING THE INSIDE OF GAS TANKS!

    NOTE: the following product(s) can only be shipped via ground transport (which thus eliminates the postal Priority Mail, postal Express Mail, or private carrier Expedited levels of service for this item) and cannot (and will not----don't even ask!) be shipped outside of the continental USA. Additionally, there may be a per-package weight or quantity restriction, and thus multiple-unit orders of this product may have to be shipped in separate packages and will incur additional shipping charges.


    HCP12358 Aftermarket RUST DESTROYER FLUID, in a 16-ounce plastic bottle. Best to transfer into an old windex spray bottle (etc.) and use with a spray nozzle.

Each:
    $ 19.95


    Here are a few other good ways to de-rust metal products:

    - soak iron (steel) parts in heated vinegar (doesn’t matter what kind) overnight, then rinse with clean water. and finally spray with fogging oil (or similar) to prevent rust from re-forming.
