CLUTCH/TRANSMISSION/DRIVETRAIN:

--Drive Chain & Sprockets


DRIVETRAIN:

Okay, once your clutch and transmission is performing admirably, now you've got to get that power out of the engine and to the rear wheel.

XJ550, FJ600, and XJ600 models used the tried-and-true reliable chain drive system for such power transmission, while all XJ650-up models used a newly developed, smoother and more maintenance-free shaft drive system. .....well, except for this one:

http://www.xjbikes.com/forums/threads/the-ultimate-chain-drive-xj-bike-that-does-exist.48461/

No matter which bike you have, we've got the repair and maintenance parts you'll need for miles and miles of trouble-free operation.


XJ550, 1984-85 FJ600, and 1992-98 XJ600 Seca II CHAIN DRIVE PARTS:

All of these models used the time-tested style of a chain-driven power transmission system. While certainly reliable and keeping with the traditional of Yamaha quality, chains by their nature will both wear, stretch, and need periodic cleaning, lubrication, maintenance, and eventual replacement of the drive chain and both drive sprockets:

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

Our line of original and top-quality aftermarket items will keep your chain-gang of components in-line, doin' time, and humming right along for years to come.


As a general rule of thumb, you can expect original drive chains and sprockets to last about 10-15,000 miles, a little more or less depending on your driving style (heavy on the throttle, or trying to pull wheelies dramatically lessens the chain life) and riding conditions (wet weather or dirty/dusty conditions will also reduce chain life) and the maintenance schedule observed (no cleaning and re-oiling of the chain or periodic tension and alignment adjustments means also you'll be replacing parts fairly quickly!).

Chain technology has changed and evolved greatly since the 1980's, and chains can now be had in three basic types----and each in a mind-numbing different grades or versions----any of which can add to the durability and service life of the chain, while also being available at different price points. We've tried to take the mystery and "salesmanship" out of drive chains for you, and have pared down our selection to what we believe is the best price-to-performance ratio on the market today.

Your original chain is what is now known as a STANDARD CHAIN, and it has no additional rings or seals to help extend the life of the pins and rollers. A good basic chain such these will last about as long as an original chain, somewhere between 10,000 to 15,000 miles.

The first step upwards in "performance" chain is an O-RING CHAIN, which uses rubber o-rings to seal off the pins from the chain side plates. Since it's the PINS that stretch and wear (and not the rollers, as is commonly assumed), anything that can be done to prevent wear to the pins is a Good Thing.......and an o-ring which seals off the pin from where it enters the roller, thus keeping dirt and grit out while helping to retain lubrication in.......greatly improves the life of the chain. O-Ring style chains can generally be expected to last about 30% longer than a standard type chain, but..........with the introduction a few years ago of the X-ring style chains, there is no longer any meaningful price-to-performance difference between O-ring and X-ring style chains. Bottom line: the very small difference in price between an o-ring chain and an x-ring chain isn't worth the cost savings, in terms of the much greater strength and longevity of the x-ring style chains. Thus we do not offer any o-ring style chains!

The top-of-the-line style chain is an X-RING CHAIN, which is really an enhanced version of the o-ring type chain. X-rings are merely o-rings that feature two or more additional sealing "faces" molded into the rubber surface of the ring, thus giving more contact and thus more lubrication sealing points for the rubber ring----which means, in the case of drive chains, more dirt and grit being sealed OUT, and more lubrication "pooling" points to hold the lube IN. X-Ring style chains cost a bit more, but you can normally expect an additional 25-40% chain life over an o-ring style chain.

And once again----the life expectancy of any type of chain will be dramatically reduced by failing to lubricate often enough (once every two weeks is recommended for regularly driven bikes) or in a proper manner (clean first, then lubricate the from both sides at the bottom of the rear sprocket) or with a proper high-quality lubricant (such as the PJ1 chain lubes that we offer).

And of course, it should go without saying, but here goes anyway!: the quickest way to wear out a chain is to use it with worn or mis-aligned sprockets. You should ALWAYS replace your sprockets (both of them, front and rear) when you replace the chain. And you should follow the proper alignment, tightening, and adjustment procedures and schedules in your service manual in order to realize the maximum chain life.


Now, all of the above has to do with the LIFE EXPECTANCY OF THE CHAIN.....and nothing to do with the STRENGTH of the chain. Regardless of which style chain construction is used, chain strength is always expressed as the "tensile rating" of a chain. which is really a measure of how much shear strength the pins have. It's a measure of how much weight a chain can hold before it shears, and it's expressed as pounds of dead weight. For an XJ550 or FJ600 engine, anything above 7,000 pounds of tensile strength is more than adequate for even a high-performance, enthusiastically driven street bike.

All of the chains that we offer are pre-stressed for maximum performance, and pre-stretched for the longest life and ease of maintenance.

Finally, to replace your drive chain you will need to obtain a chain breaker and riveter tool; not cheap but a necessary evil. And although many chains are offered with either a rivet or clip type of master link, we've always found that the rivet style performs better and more reliably than a clip style, so that is what we offer whenever there is a choice of style available.

So, there you have it. We're going to start at the beginning (at the front output shaft drive sprocket) and work our way back. Enjoy the ride!


Chain wear specifications are as follows: check the amount of FREE PLAY in your chain by placing the transmission in neutral, and the bike on the centerstand. Push up on the bottom run of chain, midway in-between the front and rear sprockets. The allowable amount of free-play is 35-40mm, and if more or less is observed, the chain need adjustment (via the puller mechanism) or replacement if no further adjustment is possible. NOTE: user experience shows that setting the free-play to 40mm~45mm (instead of the factory-recommended 35-40mm slack) will allow the chain to hold its adjustment longer, with no negative effects on chain or sprocket wear.

With the bike still up on the centerstand, check for excessive chain wear by pulling the chain AWAY from the rear sprocket, at the 3-o'clock position of the sprocket. If more than 1/2 of a sprocket tooth can be uncovered, then the chain needs to be adjusted (via the puller mechanism), or replaced if adjustment limits have been reached.

A good visual representation of this procedure can be seen at:

http://xjbikes.com/forums/index.php?threads/28367

Failure to properly adjust the chain results in "fish-hooked" sprockets, adding additional expense and efforts to your maintenance:

Please refer to a factory service or aftermarket workshop manual for further inspection, lubrication, and chain drive system maintenance procedures and techniques.



Front Output Sprocket and Hardware:

Original cast alloy steel or aftermarket upgraded hardened steel aftermarket front drive sprockets should be replaced every time a new chain is installed.

The original front drive sprocket used on all 1982 XJ400 (4G), 33M, and 35J models), 1982 XS400 (DOHC models), 1982-83 XS400 Maxim and Seca models, XJ550, 1984-85 FJ600, 1986-88 FZ600, and 1986-90 YX600 Radian models is a 16-tooth, alloy-steel gear. Upgraded gears are normally made from a higher quality grade of steel, case hardened, hard-chromed and hand-finished for a more durable and uniform fit and function.

Additionally, 15- and 17-tooth gears are also available. A 17-tooth front gear will give you slightly less acceleration (about 5% less), but will, in theory, allow for an increase in your top speed, and also decrease your engine rpm's at any given cruising speed. However, if most of your riding is on the highway, or if top-speed is a great concern of yours, then changing your drive sprocket to a 17-tooth version may be a worthy upgrade for you. Conversely, a 15-tooth front gear is a great way to increase the kick of your engine, although it will turn your ride into a buzz-box at freeway speeds! Please also see the longer discussion of gear ratios under the "rear sprocket" section further below.

NOTE: the raised “hub” or “ring” around the shaft hole in the sprocket faces the engine,

Drive Chains:

NOTE: New drive chains are normally very tight when newly installed, but will loosen after a few miles of use as the high pressure, factory injected grease in the rollers works itself into the chain. Please check and adjust as necessary your newly installed drive chain after the first 100 miles of use. NOTE: user experience shows that setting the free-play to 40mm~45mm (instead of the factory-recommended 35-40mm slack) will allow the chain to hold its adjustment longer, with no negative effects on chain or sprocket wear.

Install drive chains with the rear axle adjusted all the way forward, and with the chain adjusters fully loosened and the bike off center stand. The use of a chain puller (HCP9689) may be required to get the master link in place.

Worn, stretched, or "fish-hooked" sprocket teeth can cause extreme fitting difficulties.

Rear Wheel Sprocket, Adjusters, and Hardware:

Original alloy steel or aftermarket upgraded rear wheel sprockets should be replaced every time a new chain is installed.


The World's Fastest XJ, a/k/a Gear Ratio Analysis:

A 44-tooth gear was originally used on 1984-85 XJ600 Euro, 1989-90 XJ600 Euro, 1986-88 FZ600 Euro, and 1986-87 YX600 Radian models.

The original rear wheel sprocket is either a 45-tooth, alloy-steel gear is the original size for all XJ550 Maxim, 1982-83 XJ550 Seca, 1984-85 FJ600, 1982 XJ400, 1986-88 XJ600 Euro, and 1989-90 YX600 Radian models.

A 46-tooth gear was originally used on 1981 XJ550 Seca, 1986-88 FZ600, and XJ400 (4G0, 33M, and 35J) models.

A 48-tooth gear was used on all 1992-98 XJ600 Seca II models.

Aftermarket gears are available in a variety of different tooth-count versions, and are made from a higher quality grade of steel, case hardened, hard-chromed and hand-finished for a more durable and uniform fit and function.

A rear gear with a higher tooth count than stock will give will give quicker acceleration (but may limit top speed), while a rear gear with a lower tooth count than stock results in lower engine rpm's for any given speed, and may allow a higher top speed (if the engine is powerful enough to actually achieve it at max rpm's), but will reduce acceleration.

For a quick performance comparison, here is a chart of the various combinations of drive ratios available using any combination of either a 15-, 16-, or 17-tooth front sprocket along with either a 44-, 45-, or 46-tooth rear sprocket on XJ550 and FJ600 models:

15 front and 46 rear = 3.0667-to-1 ratio (fastest acceleration)
15 front and 45 rear = 3.0000-to-1 ratio
15 front and 44 rear = 2.9333-to-1 ratio
16 front and 46 rear = 2.8750-to-1 ratio (stock 1981 XJ550 Seca)
16 front and 45 rear = 2.8125-to-1 ratio (stock 1982-3 XJ550 Seca and all XJ550 Maxims)
16 front and 44 rear = 2.7500-to-1 ratio
17 front and 46 rear = 2.7059-to-1 ratio
17 front and 45 rear = 2.6471-to-1 ratio
17 front and 44 rear = 2.5822-to-1 ratio (highest top speed)

Note that the 16/46 (2.8750 ratio) combination was stock for the 1981 XJ550 Seca only, while all other XJ550 models used the slightly "slower" 16/45 (2.8125 ratio) combination for a more overall "balanced" performance (but please note that direct comparisons of gear ratios are not the entire "story", as transmission gear ratios and wheel/tire sizes also affect the final performance, but the above figures are provided just for basic comparison purposes).

Also, XJ550 Seca owners can reduce their RPM's by about 300 rpm's (at highway speed) if you use a 4.00 x 18 rear tire (Dunlop and Avon still offer this size) instead of the stock 110/90 - 18 tire.

NOTE: there is a lack of clarity as to whether original sprockets featured a black or bright finish. Some original advertisements and factory brochures showed a silver rear sprocket on the 1981 XJ550 Seca models, and a black rear sprocket on the 1982-83 XJ550 Seca models, while other reference materials and original owners report ALL models coming from the factory with a silver sprocket (it should be noted that there is no seeming controversy regarding the XJ550 Maxim models; all years of these bikes had a silver sprocket). However, there is no doubt that Yamaha supplied replacement rear drive sprockets in a black color, and thus many bikes you see running around with black sprockets may have a factory replacement (rather than the showroom version) sprocket on it.

DRIVE CHAIN TOOLS:

Rust Removal 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. After use, it is recommend that the de-rusted parts be immediately painted (or similar) or coated with fogging oil, lubricant, or other surface finish to prevent flash surface-rusting of the newly cleaned parts. Each:
$ 19.95



Super-Penetrant Fluids:

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.

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.

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.

Drive Chain Lubricants:

As mentioned previously, the best way to maximize the life of your drive chain is via proper and frequent lubrication. PJ1 CHAIN LUBES are generally regarded as one of the finest brand to use, what with their special formulations that are designed specifically for standard versus O- or X-ring type chains, both providing protection against moisture and rust while also providing superior lubrication.

The factory recommends a complete chain inspection, removal, cleaning, and lubrication procedure be performed every 2,000 miles. Please refer to a factory service or aftermarket workshop manual for complete chain inspection, removal, lubrication, and chain drive system maintenance procedures and techniques.

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.
