JIS Screwdrivers:

mt1) Almost every screw on these bikes are "JIS" design screws, JIS standing for Japanese Industrial Standards, and both the depth and design on the phillips-head "slot" is different than typical US slots. In a nutshell, JIS screws (which can be easily identified by the small punched single "dot" on the screw head, in-between two of the screw slots) have both deeper and "squarer" slots and thus can hold more torque than their rest-of-the-world counterparts. They also require a JIS screwdriver to take full advantage of, and to prevent rounding out the slots as typical phillips screwdrivers will do. The more "rounded" edges of a standard phillips-drive screwdriver cannot exert as much torque on the screw head (by design, actually) and will "cam-out" of the slots, taking some of the slot material with it.....and then you have what is affectionately known as a !!#&$!?**#! stripped out screw head!

So it might be a good idea to also invest in a set of quality JIS screwdrivers; trust me, they make a difference (and yes, they can be used on standard phillips-drive screws, too).

We offer these tools in three different quality grades and styles to meet your particular needs:

* Standard-Grade screwdrivers are a low-cost alternative that do a fine job in light-duty use.
* Mechanics-grade screwdrivers are a heavy-duty design and is recommended for the typical home mechanic or shop.
* Impact-grade screwdrivers feature a hardened “head” and an internal cam-drive that rotates the shaft about 12-degrees when struck by a hammer -----similar to the operation of an impact driver, but in a much more useful form. These drivers look, feel, and operate just like a mechanic-grade screwdriver above, but can also be given a sturdy “whack!” to help persuade frozen fasteners to give up their grip. Highly recommended when working on the carbs (the upper and lower rack bracket screws are a beast to remove without an impact driver ) or in any number of other situations when working on seized or rusted fasteners.

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:

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.

c9) Hitachi & Mikuni carbs THREAD CHASER AND CLEAN-UP TAPS. The soft aluminum bodies of the carbs can take a severe beating over the years, especially as it concerns their threaded holes. Steel is harder than aluminum, so you know what's going to distort, deform, or strip first...the threaded bore holes. The following professional quality tool-steel metric cutting taps will allow you to either "clean-up" or re-thread distorted or stripped threads in all metals, soft (aluminum) to hard (steel). THE TINY VERY FINE THREADS OF THE IDLE MIXTURE SCREW PORT ARE ESPECIALLY PRONE TO DAMAGE AND SHOULD BE "CLEANED" UP WITH A PASS OF A THREADING TAP.


NOTE: THE FOLLOWING TOOL KITS 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.

HCP28194 Aftermarket carb body THREAD CHASER BASIC TAPS SET. This basic set of 6 taps contains all of the different sizes for the most commonly needed threaded holes on all Hitachi and Mikuni carb bodies. Almost all threaded will exhibit some type of thread wear (distortion) or minor injury that should be repaired, especially to the smaller, more “fragile” threads on the mixture screw bores, the fuel and are jets threads, the bowl, hat, and bracket mounting holes, etc. Running thread taps thru all of these threaded holes in the carb bodies will not only make the re-assembly process easier, smoother, and more secure, but there is a certain satisfaction and surety that comes with having like-new threads that can only be described as “machinist porn” (those of you that know, will know what I mean!). Correct size taps will do the upper and lower rack bracket holes, the float bowl attachment holes, the float bowl drain screw holes, the carb hat attachment holes, the Mikuni float valve seat bracket hole, Mikuni main jet needle retainer plate holes (inside the vacuum piston), all air jet and fuel jet holes, enrichment plunger lifter bracket holes, and throttle shaft butterfly valve mounting holes. Comes with a can of cutting fluid and a t-handle tap holder tool. Note that unlike the complete taps set below (HCP28121), the taps for the Hitachi float valve seat and the choke plunger seat bores (on all Hitachi and Mikuni models) are not included in this set (those larger taps are what add significantly to the cost of the complete taps set). NOTE: due to the reality that you may use these tools only once, it is suggested that you use the tool rental option for this tap set. However, under the rental option, if you use the taps for actual thread tapping (cutting brand new threads in a newly drilled hole), then the return option is not allowed!
$ 89.95

HCP28121 Aftermarket carb body THREAD CHASER COMPLETE TAPS SET. This complete set of 9 taps contains all of the different sizes of threads found on all Hitachi and Mikuni carb bodies. Almost all threaded will exhibit some type of thread wear (distortion) or minor injury that should be repaired, especially to the smaller, more “fragile” threads on the mixture screw bores, the fuel and are jets threads, etc. Running thread taps thru all of the threaded holes in the carb bodies will not only make the re-assembly process easier, smoother, and more secure, but there is a certain satisfaction and surety that comes with having like-new threads that can only be described as “machinist porn” (those of you that know, will know what I mean!). Correct size taps will do the upper and lower rack bracket holes, the float bowl attachment holes, the float bowl drain screw holes, the carb hat attachment holes, the choke plunger seat holes, the Mikuni float valve seat bracket hole, the Hitachi float valve seat hole, Mikuni main jet needle retainer plate holes (inside the vacuum piston), all air jet and fuel jet holes, enrichment plunger lifter bracket holes, and throttle shaft butterfly valve mounting holes. Comes with a can of cutting fluid and a t-handle tap holder tool. NOTE: due to the expense of this kit, and the reality that you may use these tools only once, it is suggested that you use the tool rental option for this tap set. However, under the rental option, if you use the taps for actual thread tapping (cutting brand new threads in a newly drilled hole), then the return option is not allowed!

HCP2398 Aftermarket THREAD CHASER AND CLEAN-UP TAP, made from a high-speed uncoated steel. For use on all Mikuni idle mixture screw ports, and all Hitachi idle mixture screw ports with models using ultra-fine threaded idle mixture screws. NOTE: these threaded holes almost always need cleaning or re-tapping. Be careful when using these taps to make sure that you are cleaning and/or re-cutting the original threads, rather than any crossed/stripped threads that may be present. And beware the tiny needle tip hole at the bottom of the screw. Finally, note that the flat o-ring land (at the bottom of the screw hole) must not be damaged or gouged.......make sure that you do not run the tap in deep enough to damage that smooth land.

c9a) Hitachi & Mikuni carbs THREAD CHASER DIES. Unlike the thread taps listed above, these thread DIES are used to clean, restore, and repair threads on the threaded fasteners (screws, bolts, studs, etc.). These tools help restore that like-new feel to used bolts, and straighten and restore threads to allow for proper torque settings to be achieved and maintained. Unlike standard round dies, these dies 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 use, important to do, and when you’re done you’ll be glad you took the time to do the job properly! NOTE: these dies are not used to cut new threads, only to renew threads on non-hardened fasteners! Always lubricate the tool (or fastener) with a light oil or grease when using.

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. Oil-based lubricant penetrates down into spaces of one-millionth of an inch to handle the most reluctant seizures. Actually dissolves the rust and corrosion that causes the seizure; lubricates and displaces moisture to prevent rust re-formation. 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.

Carb Refinishing Tools:

Well, since you're going to spend the time and a lot of effort to make your carbs perform properly, why not also take them to "the final frontier"? Yes, performance is more important than appearance, but achieving a polished, "like-new" finish on your carb bodies is mostly just a labor of love, and time......rather than money.

Our special miniature POLISHING BRUSHES allow you to bring back the brilliant luster to the aluminum alloy carb bodies and bowls that makes them look showroom-fresh. Fitting into a standard high-speed dremel tool, these stiff bristle wire brushes not only remove the corrosion, discoloration, and oxidation that is typical of 30-year old carbs, but also leaves a smooth, sealed luster beauty that gives a truly professional touch to you restoration efforts.

These brushes can be used "as is", or, when combined with our coarse or fine-grit POLISHING POWDERS, makes the job that much easier and quicker. NOTE: in any case, plan on spending about 1-hour per carb to achieve a fully polished appearance.....it's tedious, but enjoyable, as you can easily see the progress as you go. ALSO.......perform the polishing procedure only after you have cleaned the carbs internally (via carb dip or other procedures), as many chemicals will react and dis-color the carb bodies!

As a final measure, we recommend spraying your newly polished bodies with our BULLETPROOF HIGH-GLOSS, 2-STAGE, FAST-DRYING CLEAR-COAT.....it's fuel resistant and non-yellowing, and will allow your labors of love to retain their beauty for many years to come.


HCP16662 Aftermarket miniature POLISHING BRUSH, 1/8" shank stainless steel bristle wire high-speed brush quickly removes corrosion and surface imperfections without displacing metal. Depending on how badly the carbs are tarnished, figure on using 2 brushes per carb body. NOTE: always wear eye protection when using these brushes, as they will tend to "shed" bristle fragments as they are used. Each:
$ 4.95

HCP16662SET8 Aftermarket miniature POLISHING BRUSHES, set of 8:
$ 32.95


HCP11198 Aftermarket BULLETPROOF HIGH-GLOSS, 2-STAGE, FAST-DRYING CLEAR-COAT WITH HARDENER. Requires 2-hours drying time to handle, and requiring just 18-24 days to fully cure. Once fully cured this clear-coat is chemical, oil, and fuel resistant, making it ideal for use on gas tanks, carbs, etc. NOTE: this clear coat is not rated for high-heat applications on engines, brake calipers, or brake rotors. 12-ounce spray can. 1 can will do a full set of carbs.
