VALVECOVER, VALVE COVER GASKETS, AND HARDWARE:
cc) OEM and aftermarket VALVE COVERS, VALVE COVER GASKETS and CAM END-PLUG SEALS, all of the parts needed to restore the top end of your engine. Our refinished valvecovers are the perfect “topper” to a restored engine, and our high-quality molded rubber gaskets or fiber gaskets fix leaks and restore a like-new seal.
Fiber-paper gaskets are used on all '80-1 XJ650 models, '82 XJ650 Seca, all XJ650 Turbo models, and XJ1100 models. Owners of these models will also need to replace the half-circle shaped cam-end rubber plugs (HP1619SET2). All other models (using the molded rubber valvecover gasket) have cam-end plugs integral (molded into) the valve cover gasket itself, and thus do not need to be ordered separate from the valve cover gasket.
Molded rubber gaskets are used on all XJ550 models, '82-4 XJ650 Maxim, all XJ700-X and XJ750-X models, all XJ750 models, and the XJ900RK models.
NOTE: if you've never replaced your rubber valve cover gasket, you're in for treat!
These spongy, rubbery gaskets have a small molded-in protruding locating-alignment "tab" (along it's entire length!) that fits into a matching, machined-in recess in the valve cover. This design works great at preventing leaks; however, given the "wiggly" nature of this gasket, its rather long and complicated outline and length, and given the fact that these gaskets tend to run just a hair undersized in overall length (compared to the dimension of the valve cover), all this means that installation can be, well, a challenge. The locating tab in the gasket tries to wiggle its way out of its groove in the valve cover, especially around the corners and bends. Both the original and the reproduction gaskets exhibit this tendency, with the reproductions being slightly worse in this regards.
The solution is to use a very tacky gasket adhesive, such as out HCP17198 hi-tack adhesive to get the gasket to seat correctly onto the valve cover before attempting install (because of the limited spaces involved, it is hard to re-position the valve cover, with the gasket glued to the bottom, back onto the head without bumping it around a bit). Although I'm sure that some people can install the gasket/valve cover correctly without resorting to such measures, it sure makes life easier if you perform this "cheat". We won't tell anyone if you don't.......
NOTE1: do NOT use gasket sealant on the bottom of the valve cover gasket. There is no sealant used nor recommended between the valve cover gasket and the cylinder head itself. Adhesive is only used to retain and seal the gasket to the bottom of the valve cover! The bottom of the valve cover gaskets (and/or the top mating surface of the cylinder head) should be wiped with a thin film of our HCP1714, HCP28407, or HCP20861 silicone grease or motor oil to lubricate the bottom edge of the gasket before installation. The use of a RTV type of gasket sealant (such as our HCP3120 or HCP25092) is recommended for use on the half-round "cam end plugs" that fit into the half circle recess on the right side of the cylinder head.
By the way, it is recommended that you carefully inspect the half-circle cutouts on the cylinder head where these rubber plugs fit into…..some heads will have an extremely sharp edge where the “circle” transitions to the flat horizontal surface of the head (where the actual valvecover gasket lays). Any ultra-sharp edge or burrs in this area will cut into the gasket and result in a leak at that spot. It’s not a bad idea to very carefully use a very fine file to knock off any burrs or reduce a razor-sharp edge to something a little less…….and “a little less” is the key! You do not want to remove any significant amount of material ----- that will cause a leak, too! ----- but just enough to where it isn’t ultra-sharp, and especially any metal edge that protrudes above the horizontal plane of the rest of the flat valvecover gasket flat surface.
NOTE2: on all models using molded valvecover gaskets, Yamaha used a mid-shouldered bolt with a conical rubber "washer" above the shoulder to exert downward pressure onto the valve cover, thus insuring adequate force on the valve cover and onto the cover gasket to maintain a proper seal (and thereby preventing leaks).
Over time, these rubber washers harden, distort, and shrink, thus losing their "pushing" ability, thus allowing the valve cover to "loosen" its force on the gasket below. This is a major cause of oil leaks from around the valve cover area, and should be one of the first areas to check and replace if you discover small leaks from around the valve cover gasket. These washers are a "must-replace" item when replacing a molded valvecover gasket. The valve cover bolts themselves rarely wear out; only the rubber washers do. Be advised that removing and installing these washers onto the shoulder bolts can be tricky, but patience and effort and maybe some silicone grease (part HCP1714, HCP28407, or HCP20861) does wonders to make this task easier.
Trying to "tighten" the valvecover bolts too much (specified torque is 7.2 ft-lbs, which is not much at all) as a method of compensating for worn-out pressure washers is a sure way to strip the threads out of your cylinder head bolt holes, which is truly and completely the definition of "no fun at all"........
The replacement rubber pressure washers include the integral metal cup washer, as original, on all versions except for the XJ900's (which originally used a separate metal washer along with a rubber pressure washer).
A great visual guide to the entire valve clearance and thus the valvecover gasket and pressure washer replacement procedures can be reviewed at:

and
http://www.xjbikes.com/forums/threads/valve-clearance-exhaust-side.94158/#post-522959
Please take special note to the section describing the procedures used to replace the pressure washers on models that used them. Once some models, there is a difference in design and style between the “inner” and “outer” washers, and they do not interchange with each other. It is always best to replace these pressure washers as complete sets (i.e. for the entire valvecover).
Also, in case you're wondering, the models that use the allen-key drive bolts to retain the valvecover will find the correct size hex key is 5mm.....
If you want to refinish your valve cover, here's the way to get that "like-new" look again:

Valve Cover Gaskets Installation Supplies:
HCP3120 Aftermarket black GASKET MAKER, large family-sized 3.8 ounce squeeze tube. Enough to do about five thousand cam end plugs! I'm sure it works well in other applications. This is for use on the half-moon end plugs (HCP1619 for non-YICS applications) and the molded-in end plugs (part of the actual rubber gasket) on YICS engines. Do not use on the paper or rubber valvecover gasket itself! Each:
$ 11.95
HCP3120A Aftermarket black GASKET MAKER, smaller 1/2-ounce squeeze tube. Enough to do a few hundred cam end plugs! It's the smallest size offered. I'm sure it works well in other applications. This is for use on the half-moon end plugs (HCP1619 for non-YICS applications) and the molded-in end plugs (part of the actual rubber gasket) on YICS engines. Do not use on the paper or rubber valvecover gasket itself! Each:
$ 7.95
HCP25092 Aftermarket high-performance aviation-grade, black, non-hardening GASKET MAKER, 1.5 ounce squeeze tube. This special high-performance sealant is ideal for use on engine case covers as a “problem solver” material which will compensate for poor machining tolerances or the slight warpage that can occur over time on precision-fit pieces. A very thin film of this material is all that is needed! Each:
$ 8.95
HCP28407 Aftermarket o-ring, oil seal, and gasket installation pure SILICONE GREASE. This small 5-gram (1/6-oz) snap-open "pillow packet" is enough for a few small oil seals, dozens of o-rings, and the like. Each:
$ 4.95
HCP1714 Aftermarket o-ring, oil seal, and gasket installation pure SILICONE GREASE. This generous 14-gram (1/2-oz.) tub goes a long way, because just like Brylcreem, "just a little dab will do ya'!" Each:
$ 9.95
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.
HCP20861 Aftermarket industrial-strength SILICONE LUBE, in a large 16-ounce aerosol can. Concentrated silicone sprays on wet, and then dries to a super-slick, clear, non-greasy, non-staining finish. Resists moisture, stops squeeks, prevents binding on all types of surfaces (wood, metal, plastic, rubber, even fabrics). Won't wash away, protect against rust and corrosion, stable from -100 degrees up to 500-F. This fluid is also a great choice for use as installation lubricant for o-rings, oil seals, etc. (similar to our HCP1714 or HCP28407 silicone grease paste) or wherever petroleum-based lubricants are not recommended.

VALVE ADJUSTING SHIMS AND PADS:
Introduction:
The periodic checking and replacement of these valve clearance shims is one of the most over-looked of all the regularly scheduled maintenance tasks on these bikes.......and with predictably negative results.
The proper operating clearance of these shims (or, in the case of XJ700-X and XJ750-X engines, the Adjusting Pads) is necessary for both the maximum power output of your engine and the longevity of your camshaft and engine's life. Allow these clearances to get too small---which they will, over time---and you run the real risk of burning the valves (especially the exhaust valve) and that's just Not A Good Thing. An engine that runs poorly, stalls, or is very hard to start after it is fully warmed up, points to dangerously decreased valve clearances. Of course, if the shim clearances are too large, your engine will be down on compression and power throughout all rpm ranges.
And if the clearances vary from their specified ranges significantly in-between different cylinders, then it makes any attempt at engine synchronization---via the adjustment of the carb "synch screws"---meaningless and a sure way to reduce both the power output and the lifetime of your engine.
www.xjbikes.com/forums/threads/carb-sync-lession.129947/#post-658338
Yamaha had a difficult time determining what the proper shim-clearance checking interval should be, as their numbers are all over the board on this topic:
* every 5,000 miles on XJ550, 650, 750, and 1100 models.
* every 16,000 miles on XJ700 non-X models.
* every 26,000 miles on XJ700-X and XJ750-X models.
* every 8,000 miles on all XJ900RK models.
Checking the clearance between the shim and cam lobe is an important and should be a mandatory part of your regular engine tune-up and maintenance procedures. Valve clearances that are too loose or too tight results in poor engine performance, hard starting, and in the case of valves which are too "tight" (meaning the clearances are less than the specified clearances) can result in repaid and expensive engine damage.
So you should periodically perform a valve shim-to-cam lobe clearance measurement. IF the clearance is out of spec, then you will need to remove the currently installed shim (using the proper valve shim bucket retaining tool) in order to determine what size shim is currently installed, and then use the shim clearance charts in the service manual to calculate what size shim needs to be used to get clearance back into specification.
The entire shim clearance checking-and-adjusting procedure is not particularly difficult, but expect to spend a couple of quality hours (all air-cooled engines) or most of the day (water-cooled engines) to check the clearances, and a few more hours to replace any, if necessary. On all air-cooled XJ engines, you will need to use the special valve shim bucket retaining tool in order to be able to extract the shims, while on all engines you will need a special size, open-end wrench in order to be able to turn over the engine manually via the left side crankshaft flat-sided nut, as well as an appropriate-sized set of feeler gauges.
You should have access to an original factory or aftermarket workshop manual that describes the proper valve clearance specifications for your engine as well as the calculation "tables" that allow you determine what size shim needs to be substituted for an already existing sized shim (if and when the measured clearances are out of specification limits).
A great visual guide to the entire valve clearance and thus the valvecover gasket and pressure washer replacement procedures can be reviewed at:
http://www.xjbikes.com/forums/threads/bigfitzs-airhead-valve-adjustment-with-pics.116006/
and
http://www.xjbikes.com/forums/threads/valve-clearance-exhaust-side.94158/#post-522959
When you remove your valve cover, be sure to inspect the condition of the valve cover gasket and replace if necessary, as well as replacing the special valve cover bolt rubber "pressure washers" that actual impart the sealing pressure to the valve cover itself.
EXAMPLE: the intake clearance spec is .11mm - .15mm. Suppose you measure the clearance on the #1 intake valve to be .08mm-----in other words, the clearance is TOO SMALL by .03mm (and thus the valve will be "tight").
Now you need to remove the currently installed shim from its bucket (using that bucket retaining tool) and see what the thickness of that shim is, because the knowledge of what the current shim thickness is the only way that you are going to be able to determine what the thickness of the replacement shim needs to be.
So you pull out the currently installed shim and it's a 265 size (meaning 2.65mm thick). Since your CLEARANCE was measured to be .03mm too small, then you need a THINNER shim to replace the 2.65mm thick shim in order to "open up" the clearance back to spec.
Shims come in thickness intervals of .05mm, meaning 2.60mm, 2.65mm, 2.70mm, etc. So since your current shim is 2.65mm thick, and you need a .03mm thinner shim, then the next available smaller (thinner) size is a 2.60mm shim.....which is what you need to use for that valve.
Using a .05mm thinner shim will INCREASE the clearance gap from the .08mm measured to .13mm, which is within the .11-.15mm spec.
NOTE: The above is the method that Yamaha recommends. I, however, recommend one additional step. When you remove that original 2.65mm shim, you are ASSUMING that it is, indeed, 2.65mm thick. Maybe.......but maybe not. The truly proper procedure would be to measure the actual thickness of the "2.65mm" shim, in order to calculate the replacement size shim that is needed. The factory calculations ASSUME that a 2.65mm shim is actually 2.65mm thick.
Suppose the original "2.65mm" shim was actually only 2.61mm thick (due to wear, etc.)? Then replacing that "2.65mm" shim with a 2.60mm shim (as the factory procedure and calculation would suggest) will only gain you .01mm in additional clearance......meaning your clearance will go from .08mm to .09mm.........still out of spec!. What a bummer and waste of effort!
So, there it is. Make sure that your measurement devices and procedures are accurate. And whatever you calculate, make sure that after you replace the current shim with a new one, re-measure the clearance again (after a few engine revolutions to allow the parts to set-up properly) and make sure that the clearance is now correct.
VALVE SHIM CLEARANCE - ADJUSTMENT KITS:
vc42) Checking your valve shim clearances is the regular maintenance one task that should definitely not be overlooked….as the performance and long-term reliability of your engine is at stake. Proper valve clearances are a must in all air-cooled engine, especially on high-performance, critical-tolerance engines such as these Yamaha in-line fours.
We’ve put together complete sets of the vital pieces you’ll need to get started on this task with our VALVE CLEARANCE CHECK KITS which contain all the basic parts and pieces you’ll need to begin the process. Note that these kits do not include any valve shims…….as you will not know what size to purchase until after the clearance-checking procedure is completed.
So if this is your first “valve clearance rodeo”, then these kits contain all the gaskets, seals, and tools you’ll need to get the job done accurately, properly, and efficiently. Subsequent clearance checking intervals will generally only the require the replacement of a few shims, but you’ll already have all the tools and supplies needed to proceed forward at a moment’s notice!

z) OEM and aftermarket replacement VALVE CLEARANCE ADJUSTING SHIMS AND PADS.
NOTE: there has always been some discussion regarding the re-use of old valve shims. The factory advice and our advice is this: "DON'T". Valve shims and pads are designed to be "wear items", much like brake shoes or pads are.
The heat-treating on the valve shims extends only a small distance below the surface face of the shim, and normal wear will "eat through" this surface hardness and can then result in much more rapid wear of the shim.
And although you will be tempted to do so, do NOT use a magnetic pick-up tool to hold or extract a valve shim from its lifter bucket, as the hardened steel shims and buckets will become magnetized and will thus hold onto any circulating metal shavings in the oil, thus concentrating and accumulating those metal particles in a place that you do not want them to be-----and resulting in a "sandpaper" action against your camshaft lobes, which no longer even qualifies as "not a good thing", but goes directly into the Very Bad Thing category of expected outcomes for your engine!

Oh, and one last bit of advice to both the inexperienced and seasoned, as well----when it comes to remove the valve shims from their buckets, please block off the cam chain passage completely with a rag or paper towels in order to prevent a "popping shim" from migrating to a place that it doesn't belong (somewhere deep inside the bowels of your engine!):

USEFUL TIP: sometimes you’ll come across an engine that has “zero-clearance” or negative-clearance valves…..an outrageous sign of previous owner(s) neglect (and, by the way, a real smoking-gun which shows that level of neglect probably applies to everything on such a bike, so you’d better double-check every critical system on such a bike twice!). Since there will be no “clearance” that can be measured, then there is no way to calculate what size shim(s) that you’ll need to get such valves back into spec, without first replacing the currently-installed shim with a much thinner shim (thin enough so that at least some amount of clearance begins to occur). If you can’t find an already-installed shim (on any of the other valves) that are small enough to obtain some amount of clearance on the offending cylinder(s), then we recommend that you order a variety of “very thin” shims from the list below, so you’ll have at least one size that will allow a clearance to be measured…..and then your correct size replacement can be calculated accurately. Based on experience, we would consider the 2.00mm - 2.20mm shims to be “very thin” for most engines.
Aftermarket VALVE ADJUSTING SHIMS, available in all sizes 2.00 thru 3.10. These are correct 29mm diameter shims with 90-degree squared edges, and are NOT Suzuki shims. Fits all Yamaha XJ models EXCEPT XJ600 Seca II, XJ700-X, and XJ750-X water-cooled engines. Select from the part numbers below. Each:
$ 9.95
Shim kits: we don’t have any of the commonly advertised “shim kits” available, as there is no way in advance to know what size (and quantity of each size) shim(s) that you’ll need. Typical shim kits contain of a few shims of each size (2.00mm thru 3.10mm), and 99% of the shims needed are going to fall into the 2.40 thru 2.80 mm size…………so you’ll be spending money on a LOT of extra shims that you’ll never need. Remember, the absolute greatest quantity of shims you’ll need to do an entire engine is only 8 shims (most probably, of 2 or 3 different sizes), so 99.9% of the time, a “shim kit” ends up costing far more than just buying the proper individual shims that you’ll need (once you’ve gone thru the clearance-checking procedure and calculations).

These plastic shims are the same size as a metal shim, so they will fit into the bucket properly, and serve as an easy-to-remove "placeholder" for a metal shim after the original metal shim is removed (for determining the size). This allows the original metal shim to be made available for re-use in another position (if it's the correct thickness), or, the plastic shim can be installed and remain in place while you await the arrival of your correct-sized replacement metal shims. These "shims" have a small central hole which makes their removal much simpler than with metal shims; a small hook tool or even a puff of air from air blaster or air gun makes them pop out, which is much easier than trying to remove an oil-locked metal shim. Since it is common that multiple shims will need to be removed/replaced during a typical clearance-setting session, it is advisable to have a number of these shims on-hand to simply the overall process. NOTE: not for use in a running engine! For use in all XJ550, 1984-85 FJ600, XJ650, XJ700, XJ750, XJ900, and XJ1100 engines. Each:

Valve Clearance Feeler Gauge Sets:
v7) Aftermarket valve clearance FEELER GAUGES SETS. These dual offset-blade design with their 90-degree angled ends makes it easy to check the valve clearance on all XJ air-cooled motors. XJ700-X and XJ750-X (water-cooled) engines will require the use of much narrower feeler gauges to check the intake valve clearances on those models.
HCP1593 Aftermarket valve clearance FEELER GAUGES SET, combined .002"/.003" blades.
$ 7.95
HCP1594 Aftermarket valve clearance FEELER GAUGES SET, combined .004"/.005" blades.

HCP159345SET---set of all three gauges, 1 each of HCP1593, HCP1594, and HCP1595 gives you all of the most common sizes needed.
$ 22.95
We also carry traditional multi-blade feeler gauge sets. Which one should you order? Well, it depends on whether you like your readings to be based in standard-size DECIMAL or [/b]METRIC[/b] readings (both gauges have the corresponding sizes in their opposite equivalents, but the "round number" readings vary between the two sets). Since these are metric bikes, and the valve shim clearance charts and the shims are denominated in metric, we tend to prefer the metric gauges:
HCP6383 Aftermarket METRIC FEELER GAUGES SET. These gauges will work on all XJ engines including the XJ700-X and XJ750-X water-cooled models, which require narrower blade-tip feeler gauges to check the intake valve clearances on those models. Aftermarket 32-blade metric set has 95mm long blades, hardened and polished, with the thin, tapered ends needed to access the valves on these models. Marked in both metric and decimal equivalents, as listed below. NOTE: these feeler gauges will fit perfectly, although you will have to rotate the blade 90 degrees to the holder for some of the inner valves on X-models. Each:
$ 17.95
Comment: the inclusion of inch measurements AND the inclusion of smaller sizes makes this set ideal for all XJ-bikes and especially for X-models.
X-engines have valve clearances in a range from .004" - .012" (0.11 mm - .30 mm)
Metric (millimeter) sizes:
.03, .04, .05, .06, .07, .08, .09, .10, .13, .15, .18, .20, .23, .25, .28, .30, .33, .38, .40, .45, .50, .55, .60, .63, .65, .70, .75, .80, .85, .90, and 1.00mm

HCP3445 Aftermarket DECIMAL FEELER GAUGES SET. These gauges will work on all XJ engines EXCEPT XJ700-X and XJ750-X models, which require thinner feeler gauges to check the intake valves clearances on those models. Complete set of 3-1/4" long straight-blade feeler gauges combines all sizes from .0015" thru .035" (each blade is also marked in its metric equivalents, from .038mm thru .889mm) on a handy storage ring. Sizes on the blades are listed in both decimal and metric dimensions. Includes a 2-1/2" long ruler. Each:
$ 16.95
Non-"X" engines have valve clearances in a range from .004" - .008" (0.11 mm - .20 mm)
Metric (millimeter) sizes:

Valve Clearance Crankshaft Nut Wrench:
To rotate the engine during valve clearance checks, you'll need the use of a proper sized open-end wrench to engage the special flat-sided nut on the left end of the crankshaft. A box end wrench or socket is not going to work. This is an odd-sized and difficult-to-locate wrench at most hardware or big-box stores.
HCP9640 Aftermarket OPEN-END WRENCH, 6" forged steel "engineer's wrench" has only one opening, and smooth black finish. Fits all XJ engines.

Crankshaft End Cover Gasket:
ec2) OEM oil pump/crankshaft end cover ("YICS covers" on models so equipped) GASKET. A great idea to replace these if you remove the case covers. Although these gaskets don't seal any fluids, you don't really want grime and gunk and junk accumulating inside the covers.
OEM oil pump cover gaskets are made from a standard duty, graphite impregnated paper material. We recommend the use of the aftermarket hi-performance paper gaskets which are designed to slightly swell in the presence of petroleum products (fuel or oil), thus creating a super-tight, leak-proof flange seal.
HCP998 OEM oil pump covers or "YICS" covers standard duty paper GASKET. Originally used under the left side cover only, but many people like to install one under the right side cover also, and they will fit either side properly.

Valve Shim Retrieval Tool:
it34) Aftermarket TELESCOPING MAGNETIC TOOL, also known as a "parts retrieval" tool. Slim, small (1/2" diameter) permanent magnetic tip extends up to 30" to allow you to get into small, deep spots and grab any iron-based material. Also works great for checking steel to determine whether it's stainless or not (stainless steel is much less---or not at all---magnetic as compared to regular alloy steels). Features a special "power-cap" magnetic cover that prevents the magnet from attaching to unwanted surfaces. Can lift five pounds.

VALVETRAIN PARTS:
Valves, Valve Guides, Valve Springs, Keepers, and Hardware:
vt3) OEM and aftermarket cylinder head VALVES, SPRINGS, GUIDES, KEEPERS, and HARDWARE correctly replace burned, worn, broken, or damaged originals. When doing a complete engine rebuild or a cylinder head restoration, make sure you carefully inspect all parts and repair or replace components as necessary, in order to insure both proper cylinder compression and, in the case of the valve guides, to also insure no oil leaks or usage.
It is recommended that certain items, such as the valve spring keepers and the valve stem seals, ALWAYS be replaced if you have the valve dis-assembled for any reason.
Always carefully inspect the INNER valve springs, as they are more likely to fatigue or break than the outer springs, and because of their "hidden" position, it is much easier to overlook such damage. Weak or broken valve springs can and will eventually lead to catastrophic engine failure!
NOTE: always install valve springs so that the tighter-wound (more closely spaced together) coils are closest to the cylinder head.

Valve Face and Seat Reconditioning:
Typically known “lapping”, this is the most effective means of touching up slightly worn or burned valves and seats, to restore like-new performance at minimum expense, and should be done whenever the head is off for service. And even after a valve grinding, a light lapping may be desirable. Modern valve refacing and reseating methods bring sealing surfaces into nearly full contact. However, slight irregularities, caused by vibration of equipment over a long period, make a lapping step the best way to be certain of a perfect job.
The proper spinning-while-grinding action, and the periodic lifting of the valve off the seat, is necessary to allow the abrasive compound to reposition itself uniformly on the valve and seat. After a final cleaning of compound from the valve, we recommend a few turns with oil to lift the remaining compound from the pores of the metal and to allow more accurate clearance adjustments. A well-seated valve, guided centrally and given proper clearance, is almost certain to give long service.
Our valve lapping tools, compounds, and complete kit makes this process easy (well, okay, a little bit “easier”) and will allow you to achieve a professional result.

NOTE: THE FOLLOWING TOOL IS AVAILABLE FOR RENTAL!!: since this tool is a one-time or infrequent use tool, it may be more economical for you to rent it from us, rather than to purchase it 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.
HCP10181 Aftermarket valve SPRING COMPRESSOR TOOL SET, comes with 5 different size adapters to allow use on all XJ-series engines, including the Maxim-X type multi-valve engines. NOTE: although this screw-type compressor tool comes with five different-sized retainer disc "adapters", you may find that none of the specific adapter sizes fits your valve spring retainers "perfectly". However, you merely need to select the size adapter that most closely fits the retainer size on your engine (never bigger, always smaller than the O.D. of the retainer disc) and use that adapter carefully (so it does not "slip" or "walk off" the edge of the retainer disc as you are applying pressure, as you DO NOT under any circumstances want it to "walk-over" the edge of the retainer and then scar the lifter bucket bore!).
Although the OEM sized adapters fit the retainer discs "perfectly" (and therefore do not pose this "walking and potential scarring of the lifter bucket bore" threat), the huge difference in price between the OEM tools listed above and this complete, high-quality compressor tool set makes it worthy of purchasing, as long as you are careful in its use. Our experience shows that the 30mm adapter will fit the retainer discs very well (or exactly on some models) on the 550-1100 engines (except the 700-X and 750-X water-cooled models). The "X" motors will use the 19mm adapter; but it will not fit the retainer perfectly, but is the closest practical size.
Comes in a handy plastic storage case.

These medium-grit, flexible HONES are just what’s needed to apply a proper “clean-up” cross-hatch finish to a set of valve guides. Hundreds of balls of round coarse-grit oxide are attached to flexible twisted-wire shafts, which when chucked into a 3/8” or 1/2” chuck standard drill (or drill press) can be used to break the cylinder wall glaze and eliminate any high spots on the cylinder wall, creating a fresh surface finish that allows rings to seat properly, insuring the highest compression and lowest oil migration. These hones will not remove metal (and are not designed to do so). Proper use requires the application of honing oil and precise control of hone rotation and linear (in-and-out) speed of motion. Just a few passes is all that’s needed , and it’s remarkably easy to use ---- its self-centering action allows you to produce a beautiful and professional guide wall finish even for a first-time user!
The use of these hones will greatly increase the success of your engine rebuild, and should be considered a “must-have” tool if your are not having your guides actually bored and/or refinished by a machine shop.

HCP22924 Aftermarket camshaft journal NON-BEARING CAM CAP. On many engines, on the right side of the cam tunnel opening there is a non-bearing camshaft cap. Unlike all of the other cam caps, which actually hold the camshaft down to the head and actually have smooth bearing surfaces…… the only purpose for these non-bearing caps is to supply a threaded hole to accept the valvecover hold-down bolt. This same cap is used on both the intake and exhaust cams, and is on the right side of the cam tunnel opening. NOTE: on the left side of the cam tunnel opening, there is a very similar-looking cap (also with a valvecover bolt acceptance hole), but that cap is an actual bearing cap. This replacement non-bearing cap, although similar, cannot be used in place of that actual bearing cap. This non-bearing cap is easily cracked and broken if its valvecover bolt is over-tightened. And unlike the original cast aluminum cap, this cap is machined from a billet of high-strength T6061 aluminum and features a much stronger profile than the original cap. Fits all of the following engines on both the intake and exhaust camshafts: XJ550, 1984-85 FJ600, 1986-88 FZ600, 1986-90 YX600 Radian, 1984-91 XJ600 Euro, all 1982-83 XJ650 Maxim (YICS) engines, all XJ700 air-cooled, all XJ750 air-cooled, and all XJ900RK, RL, N/FN, and F engines. NOTE: XJ900 engines actually use 4 of these non-bearing caps, located on both sides of the cam chain tunnel. Each:

SOME TANTALIZING THOUGHTS: although we have not----and do not know of anyone who has---there may be opportunities for performance gains via cam-swapping between different models. Here is what we can say with surety:
a) XJ550 Maxim and Seca cams can be swapped between these engines (but not with any of the 650-up engines). The 550 Seca cams are "hotter", they have more lift, and probably also have increased duration and possibly overlap.
b) all XJ650 (except, perhaps, for the Turbo models), XJ700 non-X, and XJ750 model cams will interchange. Here's the lift variances between them:
Intake:
* 650 models (except Turbo): 8.50mm
* 700 non-X models: 8.80mm
* 1981-83 750 models: 8.80mm
* 1984 XJ750RL models: 8.80mm
Exhaust:
* 650 models (except Turbo): 7.80mm
* 700 non-X models: 8.30mm
* 1981-83 750 models: 7.80mm
* 1984 XJ750RL models: 8.30mm
Since the cam lift durations and overlap specifications are not available for all models, we can only (for now) guess what those differences are; however, it would be reasonable to speculate that the 700 non-X and XJ750RL cams are the "hottest" of the bunch, followed by the 1981-83 750 cams, and lowest on the totem pole would be the 650 non-Turbo cams.
Although camshaft design and swapping is a real black art, as not only are lift, durations, and overlap issues involved, there's also cam-timing considerations as well as the interaction between all those factors and cylinder size, air flow into and out of the cylinders, etc. to account for.
Please note that in order to correct (or enhance) other design parameters or issues, it is sometimes best to swap out ONLY the intake OR the exhaust cam (rather than both)......so much depends on the engine and bike in question, the intended usage, rpm power range desired, etc.
Like we said, a black art....... Remember, "hotness" in camshafts, just like beauty, is in the eye of the beholder, and it depends on whether your definition of "hot" is "low-end power", "all-around power", "high-end screamer", or some other variation of the above.
If anyone has any experience with cam swaps on these engines, please let us know what you did, and how it worked out!!
c) XJ700-X and XJ750-X cams do not interchange with any other XJ-series engines.
d) XJ900RK and RL cams----these we just don't know about. We BELIEVE (but cannot assure you) that they will interchange with all XJ650, XJ700 non-X, and XJ750 engines. If so, they are probably the "hottest" cams available.
e) XJ1100/XS1100 cams do not interchange with any other XJ-series engines.
Camshaft Chains:
dd) OEM and aftermarket CAMSHAFT CHAIN, high strength roller chains exactly replace your stretched or----hopefully not!----broken originals.
NOTE: all replacement cam chains are sold as an "endless chain", meaning it comes riveted together. In a situation where you have the engine all apart, it can be used as is, because you'll have side access to the gear on the crank. If you will be installing a new chain into an assembled engine, then you will have to break one of the links in order to "drop and drape" the chain over the crank gear.......and thus will also need a new master link in order to put the chain back together again.
And whenever you replace your camshaft drive chain, you should also take a good long look at the plastic cam chain guides, and consider the replacement of those items too.
NOTE: make absolutely sure that your cams and chain are clocked correctly to your crank, or your motor might easily become toast. Although there is no substitute for having a factory or aftermarket service manual in performing this procedure, here are the basic ideas involved:

Cam Chain Tensioners:
dd17) OEM camshaft CHAIN TENSIONER. These spring-loaded tensioners exert a steady pressure on the cam chain rear travel guide (front guide on the XJ1100 models), thus keeping proper tension on the camshaft chain......important for both optimal chain life and quiet valvetrain operation. By design, cam chains stretch over time and must have their tension adjusted, and these manual-adjusted tensioners (used on all XJ550 engines, all 1980-81 XJ650 Maxim and Midnight Maxim models, the 1982 XJ650RJ non-yics engines, and all XJ1100 engines) and automatic tensions (all others) are a critical component of your engine's longevity and performance.
The secret life of cam chain tensioners can be explored further at:
http://xjbikes.com/forums/index.php?threads/24597
Yamaha specifies that for the manual-tensioner models, the adjustment should be checked and adjusted (if necessary) every 5,000 miles. Automatic tensioners should never need checking, as they should adjust themselves, well, automatically!
Here's some tips on how to go about doing this adjustment properly:
http://xjbikes.com/forums/index.php?threads/23008
NOTE: the automatic cam chain tensioners used on the XJ650, XJ700 non-X, XJ750 non-X, and all XJ900 engines are completely interchangeable and can be used to replace the original manual cam chain tensioners that were used on the 1980-81 XJ650 Maxim, Midnight Maxim, and 1982 XJ650RJ Seca engines.

NOTE: This o-ring does not fit down into the cavity where the tensioner locking bolt goes into the body of the tensioner case; that cavity has a double-chamfer, and the HCP2173 washer (above) on the bolt stops against the locknut-threaded portion. When you tighten the adjuster bolt itself, that washer presses the o-ring against but not completely into the outer chamfer to seal it. Once this o-ring gets dried out and hard, it can be pressed all the way into the cavity and it stops doing its job and a thus a common source of oil leaking develops there.

Tensioner Case-to-Cylinders Seals and Gaskets:
All OEM gaskets are made from a standard duty, graphite impregnated paper material. We recommend the use of the aftermarket hi-performance paper gaskets which are designed to slightly swell in the presence of petroleum products (fuel or oil), thus creating a super-tight, leak-proof flange seal.
