XJ900 MODELS FORK TUBE PARTS:
NOTE: items marked below in red are the parts typically needed when doing a basic fork system rebuild.
A good visual review of the procedures needed for rebuilding these forks can be seen at:
http://xjbikes.com/forums/index.php?threads/4067
Note that this link shows the guts on the later XJ900 models fork systems (without the anti-dive system), but is pretty much the same as on the earlier versions with the anti-dive system.
The secret workings of the anti-dive units can be seen at:
https://www.xjbikes.com/forums/threads/xj900rk-anti-dive-stripdown-how-to-with-pics.44997
And these incredible 3-D renderings of the inner workings of a forking system gives a great visualization of the internal components (it is based on the 1982-83 XJ650 Maxim forks):
http://xjbikes.com/forums/index.php?threads/29616
NOTE: XJ750 Police (37H models) used the XJ650 Turbo master cylinder with XJ650 Turbo/XJ750 Maxim/Midnight Maxim calipers, XJ650 Turbo rotors, and XJ900 style forks with anti-dive.
FORK TUBE REBUILD KITS:
We now offer both a BASIC FORK REBUILD KIT and PERFORMANCE FOR TUBE REBUILD KITS so that you can get all the typically-needed rebuild parts under one simple part number. Each kit is specifically assembled and correct for your particular model bike.

$ 5.95
Inner Tube Fork Springs:
NOTE: the following springs are correct for the XJ900RK and RL models, XJ750RL (44X Canadian and 45T Australian models), and will also fit the XJ900 N, FN, and F model fork tubes, but we do not have the information for the non anti-dive forks in regards to spring spacers or oil fluid capacities required. Original non anti-dive fork springs (XJ900N, FN, and F models) are 5mm shorter than anti-dive springs (XJ900RK and RL), so it is safe to assume that a 5mm (or greater) spacer may be needed, and the oil level adjusted to achieve a 168mm height.
HCP9439 Aftermarket front suspension COIL SPRINGS, one pair does both forks. For all XJ900RK, XJ900RL, XJ750RL, XJ1100, and all XS1100 models. No spring spacer is needed when using these springs on the XJ900RK and RL models. NOTE: due to the difference in size of this spring versus stock springs, you will need to use approximately 31 cc's less fork oil (for a total of 255cc's per tube on the RK and RL models, and 276cc on all other XJ900 models) when installing these springs, or adjust to a 164mm oil level. NOTE: springs should be installed with the tighter (more-closely spaced together) coils towards the top of the fork tube.

NOTE: the order of installation for the above washers is as follows (and only applies to bikes with anti-dive front fork systems, i.e. the XJ750RL, XJ750P (37H model), and XJ900RK and RL models):
Order of assembly of 1984 XJ750RL, XJ750P (37H model, and XJ900RK/RL Seca oil lock valve assembly components onto damper rod:
NOTE: the Yamaha factory service manual has an incorrect written description and an incorrect image showing the assembly order of the “oil lock valve” components onto the damper rod, showing the two wave washers being adjacent to each other. The correct assembly sequence --- as shown below --- is for the wave washers to be separated by the flat shim washer:

Lower Tube Anti-Dive Unit Parts:
The front fork ANTI-DIVE SYSTEM on these models are almost always in need of a complete, thorough cleaning and rebuild. While many people claim that the anti-dive system is a "useless" feature, the real reason may be that the system is so internally fouled and seized that it simply is not operating, at all!
Anti-dive control units are divided into an "upper" (or "top") section, which is the brake plunger assembly....this upper section is where the brake hose, from the brake caliper, attaches. The brake fluid BLEEDER VALVE is located in this upper section, as well as the brake plunger piston unit. The O-RING on the plunger and on the screw-in piston head should be replaced during a rebuild procedure, as well as a thorough cleaning and polishing of the piston bore. The removal of the piston head requires the use of a special reverse-hex tool, part HCP16049.
The "lower" (or "main") section of the anti-dive unit is the larger damper piston assembly (which is bolted to the fork tube), and which contains the damper actuating piston and spring. Under hard braking, the brake fluid pressure forces the brake plunger (in the top "brake plunger assembly" section) to push down on the damper piston and its spring, restricting the flow of fork oil in the fork tubes, thus "stiffening" the fork system temporarily----and reducing the amount of front end "dive" during hard braking. The O-RING on the plunger should be replaced during a rebuild procedure, as well as a thorough cleaning and polishing of the piston bore. And the housing-to-fork tube O-RINGS should also be renewed.
Here's a good view of the components of the lower damper piston assembly on the XJ750-D, XJ750P Police (37H model), and XJ900RK and RL models anti-dive unit can be seen at:

NOTE: to dis-assemble the brake plunger assembly piston for cleaning and replacement of the o-rings, you will need this special tool to extract the threaded plug from the housing:
HCP16049 Aftermarket fork anti-dive brake plunger assembly REVERSE HEX SOCKET TOOL. This tool allows the easy removal and installation of the "inverted/reversed" hex-drive plug used on the top of the anti-dive units on all XJ750-D, XJ750P (37H model), XJ900RK, and XJ900RL models.
$ 19.95
NOTE: if you want to disable your anti-dive system, you will need to remove the hose from the caliper to the anti-dive unit (and replace the caliper end double-depth union bolt with the single-depth union bolt used at the anti-dive unit end of the hose) and block-off the anti-dive fluid port with this plug:
HCP12991 Aftermarket brake system fluid port BLOCK-OFF PLUG, correct size hex-drive set-screw is used to replace a brake hose union bolt when not in use. Use 1 per anti-dive unit.

Silver-painted covers come with mounting screws and a pre-load adjuster bolt which allows you to apply a small amount of pre-load (“pressure”) to the lower plunger and create a custom compression/rebound effect to your forks. Sold in a matched LH/RH set. Silver finish is correct for XJ900RK and RL models, but will also work on XJ750-D and XJ750P (37H models) systems.

Anti-Dive Rebuild Kits:
No need to guess what parts you're going to need......our complete ANTI-DIVE REBUILD KITS take all the guesswork out by supplying you with all of the parts necessary. Kits contain all of the rubber and plastic seals, boots, o-rings, circlips, washers, standard bleeder screws, drain screws, and hardware need to do a complete and thorough rebuild of these units. Experience how your anti-dive units should actually perform by rebuilding them correctly! NOTE: the adjuster screws (HCP23505) are not included in these rebuild kits and should be ordered separately (see listings below) if they need replacement.
The most difficult part of the rebuild process is is the installation of the thin "wavy" wire clip, which require simultaneously compress the main spring and getting the wavy clip into its retaining groove. Here's a helpful link on this issue:

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.

Assembly Fluids and Lubricants:
Anti-Seize Paste:
xx1) Fastener ANTI-SEIZE PASTE. Yeah, it's smelly and makes a slippery 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 "base-metal" 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.

xx2) The next most important tool: fastener THREAD LOCKER FLUIDS. Use on any fastener that you don't normally ever remove, to make sure that it stays that way. Comes in a variety of formulas, each one designed for a specific use as explained below. NOTE: the damper rod retaining bolt (in the very bottom of the fork tube lower leg, screwing up into the bottom of the damper rod) requires the use of the HCP1267 / HCP27756 medium-strength or the HCP1268 high-strength thread-locking fluid. Yamaha recommend the high-strength fluid, but we’ve found that the medium-strength fluid works as well and makes future dis-assembly a bit easier.

FORK OIL:
Unlike motor oil or gear oil, fork oil's major purpose is not lubrication.....rather, it acts as part of the suspension system, providing both damping and rebound control functions. The different "weight" or viscosity of fork oils allows you to modify the ride and handling characteristics of your bike in a fairly simple way.
And yes, it IS a lubricant also!
Although many people----including, unbelievably, Yamaha itself----recommends the use of engine motor oil as a substitute for fork oil, this is not a very good idea. Engine oils (or any multi-viscosity oil) uses additives and detergents that, while wonderful in for their intended purposes inside an engine block, tranny case, or rear drive unit, are not such a good idea inside forks. Forks operate at a much lower temperature and temperature RANGE than engine and drivetrains do, and thus do not need all those additives. And fork oil also tends to contain higher percentages of molybdenum disulfide and anti-foaming agents than engine or gear oil, both of which are very important to proper fork operation.
As a small example.......most motor oils are of a multi-viscosity nature (such as 10W30) which change their viscosity in relation to their temperature (thin when cool, thicker as they warm). A very necessary and useful feature for an engine, where you do not want your oil thinning out as the engine warms up. Not such a good idea for your suspension----unless for some reason you WANT your handling characteristics to change (get stiffer) as the forks heat up!
Proper fork oil levels and scheduled change intervals are important for fork performance and fork part longevity.....water contamination, as well as particulate wear will accumulate in fork oil, and since there is no oil filtering mechanism within your forks, the only way to get the grit and gunk out (before it chews up your oil seals and slider bearings!) is to change your fork fluid regularly. Yamaha recommends a fork fluid change every 10,000 miles or 24 months (all models except XJ700's), or every 16,000 miles or 24 months (all XJ700 and XJ750-X models). If you just bought a used bike, we recommend you do a fluid change as soon as possible, because just like other routine maintenance tasks (besides engine oil changes), this is one that has very likely been ignored for the last 10-12 years!
HINT: there’s a puddle of fluid under your wheel, in the area of the brake caliper. Unless the source of the leak is fully obvious, how can you tell if it’s brake fluid of fork oil? Try to mix a few drops of water into the fluid; fork oil (or engine/gear oil) won’t mix and the water will “ball up”; brake fluid will integrate with water and absorb the water.

1982-84 XJ1100 Maxim and Midnight Maxim: 210cc or 7.10 fluid ounces. 10W fork oil. Fork oil level is specified as 210mm (8.27") below the top of the tube without the spring installed, forks fully collapsed.
IMPORTANT NOTE: the above fork oil VOLUMES are for use only when using the stock fork springs. The use of aftermarket performance front fork coil springs will change those volumes, since aftermarket springs are thicker than stock----and thus displace more oil. Using the stock oil fluid VOLUME with aftermarket fork springs is a sure way to OVERFILL your forks, with the very real possibility of blowing out fork seals.
Unlike with your engine oil, where a bit too much or too little oil volume in the crankcase is not really a significant concern, with fork oil, too much or too little can cause real problems (too much oil can result in blown oil seals and a stiff, harsh ride, while too little oil volume results in excessive foaming, a soft mushy ride with possible bottoming, and erratic fork performance and lots of front end "dive" upon braking).
A better way to determine the amount of fork oil that is needed and necessary is via the measurement of the fork oil LEVEL within the tubes.....sort of like measuring the oil level with a dipstick. Yamaha does not specify this level for all models; and in any case, if using aftermarket springs, the factory oil level recommendation is not always useful. The maximum oil level should be 5-1/2" (140mm) below the top of the inner fork tube, measured with all internal fork tube components installed EXCEPT FOR THE SPRINGS, and with the inner fork tube fully collapsed into the lower (outer) tube.
In order to be as accurate as possible, we recommend the use of a suitable measuring device, such as the HCP1728 oil level syringe listed further below.
And finally, the fork oil viscosity can be changed from the factory recommendations to give a softer or firmer ride.......the lower the viscosity, the thinner the oil, and the softer the ride (i.e. 5W oil is thinner than 10W which is thinner than 20W, etc.) In this regard, you would certainly be correct in thinking of fork oil as a suspension "tuning tool"! Note that a thicker oil viscosity will have much more effect on the fork "rebound" characteristics than it will on the fork compression dampening function.

ffo3) Red Line Oil products line of SYNTHETIC FORK OILS are some of the best, highest-performance fork oils developed specifically for this purpose. They provide exceptional shear lubrication, are highly resistant to any viscosity changes, and provide excellent seal lubrication as well as very high anti-foaming properties. All of these oils are completely compatible with each other, which means that different weights can safely be mixed with each other to create "custom-weights" of fork oil for the utmost in suspension tuning flexibility. NOTE: oils, if mixed for a different viscosity, should be done in a large enough batch to provide enough oil for both front forks. You do NOT want to be running different oil viscosity's in the left and right fork tubes!
Also, do not mix different brands, styles, or types of oils........you can only safely mix forks oils together from one manufacturer!

Fork Tube Oil Level Gauges:
HCP1728 Fork tube oil fluid level measurement GAUGE AND SYRINGE. This handy tool makes the measurement of the fork oil level easy and accurate. NOTE: the proper amount of fork oil is determined via the measurement of the fork oil LEVEL (distance below the very top of the inner tube) rather than a volume AMOUNT of oil specification. Too little oil will make the ride mushy, while too much oil makes the ride harsh (and can blow out the oil seals!)

ffl4) Aftermarket fork oil measurement GRADUATED CYLINDERS. The best way to measure the precise amount of fork oil fluid is via the use of these lab-quality measurement cylinders. Available in either transparent (clear) or translucent (cloudy) durable plastic construction, they all have easy-to-read scale numerals (milliliters) and feature a "non-wetting" inner surface coating that prevents the concave "meniscus" from forming at the top of the fluid, thus insuring a much more accurate level reading. Large bases insure stability while large spouts make "the pour" easy and prevent messy drips. Very useful device to have for front fork oil changes.
