WHITE BROTHERS E-SERIES MANUALHONDA XR600R (‘85-’87, ‘91-’98) & XR650L(‘93-’98)INTROThank you for purchasing White Brothers revolutionary E-Series exhaust system. A system so uniquely advanced, thatwe have patented the shape and technology. Through years of being the leader in four stroke performance products, wehave come to know what you want: increased performance, innovative design, easy installation, technical support, andmost importantly, value for the dollar. The new E-Series is the cumulation of all these criteria, and much more.Not only is the new E-Series exhaust systems available for most popular Offroad bikes and 4 wheelers, but also forSportbikes, Harley-Davidsons, Cruiser, Snowmobiles, and even Automotive applications! Give us a call for specific applications.Unlike many other exhaust system manufactures, all E-Series exhaust systems are developed exclusively on the WB inhouseDynojet dyno. After development for maximum horsepower and torque, they are painstakingly fitted to perfectionfor easy, no hassle installation. Then, and only then, are they test ridden under the most extreme conditions, by some ofthe most fearsome test riders on the planet. These are the same riders that thrash the OEM test bikes for the majormagazines. We do this to determine if dyno performance and track performance are perfectly matched. Bottom line,you get products that have been thoroughly put to the test.The overall design of the system from a styling standpoint was extremely important to us. The E-Series silencer body,discs, and end cap, being an ELLIPTICAL SHAPE, give a much improved fit to the motorcycle. Even the end cap, thatactually has no exhaust outlet hole in it, was thoroughly thought-out to give you an esthetic appeal. The entire unit providesbetter clearance, more aerodynamic shape, better flow, and most importantly, more horsepower than conventional exhaustsystems.Another innovative feature is that we use stainless steel, aluminum, carbon fiber, and/or titanium componentsthrough-out. Our stainless steel is 304 series; virtually impervious to rust or corrosion, and you never have to worry aboutplating or paint flaking off. Our aluminum silencer bodies are made from 6063 extrusion. Our aluminum specific fitmounting brackets are manufactured by the extrusion process, then CNC’d to perfection. Our carbon fiber silencer bodiesare built to standards unheard of previously (but that’s our secret) and in a four twill pattern. Our titanium head pipes arefrom commercially pure stock normally reserved for the aircraft industry. Only the finest, most exotic materials for such arevolutionary new product are being utilized.


FREQUENTLY ASKED QUESTIONSQUESTION: Why doesn’t the end cap have a holeANSWER: The end cap has no hole because the exhaust exits through a precise gap in the E-Series diffuser discs.The E-Series Discs create a suction that extracts spent exhaust gases from the pipe thuscreating a cleaner, hotter burn on the next compression stroke. In addition, exiting theexhaust through the discs, and not an open hole, enables the E-Series to be a U.S.F..S.approved spark arrestor.QUESTION: Can I run a open end cap?ANSWER: Yes, but you will actually lose horsepower and torque. For example, on the Yamaha YZ400F, theE-Series loses over 2 horsepower on the dyno with the end cap & discs removed! You will also lose theability to adjust powerband, sound levels and jetting; as well, the system will no longer be a U.S.F..S.approved spark arrestor. If you choose to run an open end cap, simply remove the blank disc and boltthe end cap back on.QUESTION: Do I have to run the E-Series Discs?ANSWER: Yes, but only if you want maximum horsepower, maximum adjustability, and a U.S.F..S.approved spark arrestor.QUESTION: What is the minimum/maximum number of E-Series Discs I can run?ANSWER: The minimum number of Discs you should use is 4. This will still be flowing the equivalent of astraight through one inch hole, normally still much more than an OEM system. The maximum numberdepends on the diameter of the core. In most cases, this will be somewhere between 18 & 28. Most systemsutilizing a 2” core will make maximum horsepower with 7 to 12 E-Series Discs. It is very importantto remember that more Discs do not necessarily mean more horsepower. Every engine/exhaust systemhas its “sweet spot”. See your individual dyno chart for the best combination to begin with.QUESTION: Do I need to re-jet?ANSWER: No. The E-Series is designed to work with stock jetting, while increasing horsepower. If maximumhorsepower via additional modifications such as aftermarket air filters, pistons, cams etc is your desire,rejetting may be required. Refer to the tuning guide for additional information or contact ourCarburetion or R&D departments for assistance.HOW THE E-SERIES DIFFUSER DISCS WORK WITH YOUR ENGINEAs a 4 stroke engine enters the exhaust phase, the piston moves upward, and the exhaust valve opens as spent gasesflow into the exhaust pipe making room for fresh fuel. There is however a quantity of unburned gases that remain in thecombustion chamber. It is at this instant, when both intake valves and exhaust valves open, that a properly designedexhaust system can help scavenge as much of the residual gas as possible. The more efficient the scavenging, the lessdiluted the incoming fuel-air mixture will be.As the exhaust valves open, a shock wave is generated which travels down the pipe. When it reaches the end of thepipe, negative pulse is reflected in the reverse direction. If the length of pipe is adjusted so that the suction wave arrivesback at the exhaust valve just before it closes, a vacuum is created, allowing the cylinder to be charged with a purer mixture.The inertia in one moving exhaust packet assists the flow of the next charge. A purer mixture can now enter eachcylinder, resulting in stronger explosions and more power.Essentially, this type of tuning produces an increase in power over a relatively small RPM range. The suction wave producedis a combination of high energy and short duration. A wider powerband can be created with the use of a diffuser.There are two types of diffusers on motorcycles; Conical and Radial. A Conical diffuser is commonly called a megaphone(or S-Bend/Tail pipe in some cases). A radial diffuser is the E-Series Disc. Basically, a diffuser creates suction waves witha lower energy peak and longer duration. A simple way of understanding the process is thinking of a diffuser as creatinga continual series of suction waves, providing effective cylinder scavenging over a much wider RPM range.So how does a megaphone differ from the E-Series Discs? They both cause a suction. They both create diffusion aswell as static & dynamic pressure. They both work on the “Bernoulli Equation” affect, relating total flow of energy beingmade up of two components (static & dynamic pressure) and is a constant. In other words, the total power or energystored in the flow is the same at every point. As one component changes, the other changes the opposite amount to keepthe total the same. So as the flow area decreases, the velocity must increase (and vice/versa). A carburetor “venturi” is agood example. At the throat of the venturi, the area is smaller and the velocity is greater than at the inlet or outlet.Consequently, the static pressure at the throat is lower and creates a suction. When a megaphone is added to a straightpipe, the final exit velocity where the exhaust enters the atmosphere is reduced because the exit flow area is now larger. Inthe megaphone inlet, where velocity is greater, static pressure must be lower than at the exit. Since the exit pressure isatmospheric, the static pressure at the inlet is below atmospheric. Below atmospheric pressure means that there is now asuction at the end of the straight pipe when the megaphone is added. The E-Series Diffuser Discs create the same effectas a megaphone, with the added benefit of being easily and readily tunable, as well as dispersing the sound level over abroader area. Like changing megaphone lengths and diameters, the E-Series Discs allow you to adjust for Power, Sound,and Jetting levels, only now you can do it in minutes.1


GENERAL TUNING GUIDEUnless otherwise noted, it is highly recommended that you do not change the jetting after bolting on your new E-Seriesuntil you first try it with the standard and/or existing jetting, or the jetting that is noted in the instructions for your specificmodel. The E-Series Discs are designed to maximize flow without necessarily adding fuel (changing jetting). So manyelements affect jetting such as altitude, weather conditions, engine and/or carburetor condition and cam timing etc. Evendifferent riders will affect this. For instance, a novice who rides at lower throttle settings may notice more changes withthe pilot and/or needle circuit. A professional using maximum throttle may not notice changes as much on the pilotand/or needle circuit, but will only be concerned with how it carburates on the main jet. Again, first bolt on the systemand try it before making any changes.Bolt the system on with the number of E-Series Discs supplied in the kit, then go out and ride it. Note the power andhow it carburates compared to stock exhaust system. We have many cases where actually using less discs, increased thehorsepower significantly. Your individual dyno chart for your model will show you the best overall combination to use.All things being equal and in good working condition, a lean condition will be noted as a hesitation, increased temperature,loss of power and(or) back firing/popping on deceleration. A rich condition will be sluggish performance, blacksmoke, fouled spark plugs and(or) increased fuel consumption. Altering the number of E-Series Discs can improve andsolve most of these conditions. When you understand how they work in conjunction with each other, tuning becomes avery simple procedure.In the simplest form, increasing or decreasing the number of E-Series Discs basically increases and decreases the sizeof the outlet hole. Adding Discs increases the outlet hole size. Subtracting Discs decreases the outlet hole size. In mostcases, 4 Discs will equal the flow of a stock exhaust system. Equally, 28 Discs is the maximum number of Discs (providedthe silencer core is large enough to handle this amount of flow). The core size will also affect the number of Discs you areable to fully utilize. The chart below will provide you an example of how the Discs relate to flow/core size. You can notethe core size in your particular E-Series by removing the End Cap/Disc assembly and measuring across the O.D.of the perforatedcore. Most E-Series come with a 2.0” round or 2.25” elliptical core.Number ofDiscsCubic Inches ofFlow(size of hole/or corestraight through)481216182428.961.361.661.922.032.352.54By adding E-Series Discs, you are increasing the outlet area and thereby increasing: the powerband for more top-endpower, the sound level and leaning out the carburetion. By subtracting E-Series Discs, you are decreasing: the outlet areaand thereby decreasing the powerband for more bottom end or torque, the sound level and enriching the carburetion.Remember, using more or less E-Series Discs does not necessarily equate to an increase or decrease in horsepower.Every engine has its “sweet spot”. And of course every person has their preferred powerband preference. Your new E-Seriessystem has been supplied with enough Discs for an optimum overall powerband response, sound level, and stock jetting.Additional Discs are available to provide you an even broader choice of tunability.While it is difficult to determine without a dyno and EGA machine, the exact power increase and/or jetting for eachmachine , the dyno graph and jetting specifications provided within this manual will give you a good base. Please contactour Carburetion and/or R&D departments with any questions you may have. All you need do is tell us what it is doing ornot doing. We can then tell you what to do to correct it. Above all, do not be afraid to experiment with the Discs. Your newE-Series is fully tuneable. Adding and/or removing Discs can and does make a huge difference!2


CARBURETOR CIRCUITS & THROTTLE POSITIONSWhile tuning and/or diagnosing any glitches in your powerband that may arise, the following will provide you with a basicunderstanding of which circuits are affected during a particular throttle position. In most cases, adjusting the number of E-Series Discs will improve and/or fix most circuit problems. In case additional adjustments are required, this section will helpyou locate and solve the problem. It is important to remember that adjusting carburetion should only be attempted on anengine in good running condition that is thoroughly up to operating temperature. Do not make adjustments all at once, andmost importantly, do not make adjustments until first trying the exhaust system with the existing jetting. Then trying to adjustby varying the number of E-Series Discs. Find the affected throttle position (circuit) and work on that area only. Doing one stepat a time will ensure optimum performance and smooth efficient operation.Pilot Jet - Up to 1/4 throttle - Controls fuel flow through the idle circuit - Mixture is adjusted by means of the mixture screw -There are two types of mixture screws - Fuel Screws and Air Screws ]- A Fuel Screw, as the name implies, meters fuel - A Fuel Screw will be located on the engine side of the throttle valve, usuallyon the bottom of the carb - Turn in to lean mixture - Turn out to richen mixture - The engine should have a smooth, steadyidle with the screw between 1/4 and 3-1/2 turns out from fully bottomed (gently!) - If the engine requires more than threeturns out, the pilot jet may be too lean - If it requires less than 1/4 turn, it may be too rich.- An Air Screw meters air - An Air Screw will be located on the air cleaner side of the throttle valve, usually on the right or leftside - Turn in to richen mixture - Turn out to lean mixture - The engine should have a smooth, steady idle with the screwbetween 1/2 and 2-1/2 turns out from fully bottomed - If the engine requires more than 2-1/2 turns out, the pilot jet may betoo rich - If it requires less than 1/2 turn, it may be too lean.Symptoms and/or adjustment - With the idle at approximately 1000 rpm, turn the air screw mixture in slowly until the idleslows or becomes erratic, then begin turning the screw back out until it again becomes erratic. Count the number of turns inbetween the two positions. Set the position of the air screw between these two conditions, which should also be your smoothestidle . Finally, adjust the idle screw if necessary to approximately 1000 rpm again.Jet Needle - from 1/8th to 3/4” throttle - Controls fuel flow through needle jet - Raising or lowering the clip location on thegrooves, richens or leans fuel flow, as well as determines at what throttle position the tapered part of the needle is to be raisedout of the needle jet - Raising the needle (lowering the clip) richens the mixture - Lowering the needle (raising the clip) leansthe mixture.Symptoms and/or adjustment - Accelerate to 1/2 to 3/4 throttle, preferably in top gear. If acceleration seems weak, soft orflat, or the engine responds slow when the throttle is quicklyopened, the mixture is too lean. Lower the needle clip one positionto raise the needle. Conversely, if acceleration is crisp and strong,but hesitates or shutters as the throttle is closed from 3/4 to 1/2, themixture is too rich. Raise the clip one position to lower the needle.The optimum setting will be crisp acceleration, with no load up(rich) as the throttle is backed off.Main Jet - from 3/4 to full throttle - Controls fuel flow as the jetneedle is lifted far enough out of the needle jet. Until this point(throttle position), the main jet has no effect on mixture strength. Alarger # jet richens the mixture - A smaller # jet leans the mixture.Symptoms and/or adjustment - The main jet is the last jet youdeal with and by far the easiest to diagnose. You will only change themain jet if a problem exists at 3/4 to full throttle. Any other problemsin the carburetion are not affected by the main jet. The two easiestways to find the optimum setting are:1) Set-up an area approximately 50 to 100 yards long. Havesomeone time you through this area. As you pass the entry, open thethrottle fully (on the main jet circuit) and motor through this area.Essentially, the jet size that provides the least amount of time to runthrough this, is the correct main jet.2) Starting with a fresh set of spark plugs that have been run forat least a few miles to gain some color to them, run the engine(under a load) for approximately a minute or so at 3/4 to full throttle.Then, in a safe area, pull in the clutch, hit the kill switch, andleave the throttle in its wide open position; all at the same time andcoast to a stop. Then remove the spark plug and inspect its condition/color.The porcelain should be a reasonably clean color/condition,light gray to brown is good. If the plug is black and/or sooty,the main jet is too rich (big) and you should go down in size to asmaller number. If the plug is white, with no apparent change incolor from brand new, and the engine appears to be running hotterthan normal, it may be lean (small). You need to go up in size to alarger number.3

Place a small amount of the 1cc tube of high temp lube (provided) onto the threads of the 6 socket headcap screws (provided). Install the entire assembly onto the core/silencer base and snug the screws down.Tighten securely in cross pattern with the 4mm hex key wrench (provided). When tightened securely, thediscs provide a spring back affect, similar to a lock washer. Do not over tighten. Check periodically.When adding or removing discs, always be sure to use asmall amount of high temp lube on the screws toensure that the threads will not gall or seize.Correct direction of discsPATENT PENDING6


MAINTAINANCETo clean the aluminum and/or stainless steel components, simply use soap & water. For blemishes and/or discoloration,simply use a fine scotch-brite pad to touch up these areas.For Carbon Fiber components, again use soap and water to clean. A light coating of a good automotive wax will helpdirt/mud slide off easier the next time around.After washing, towel off the system and start your engine and warm thoroughly to operating temperature to remove allcondensation and/or water.The silencer packing cartridge is an exclusive blend of synthetics and steel from White Brothers. It will provide youwith long life and easy maintenance. To repack the silencer, simply remove the button head screws securing the diffuserdisc base (where the discs sit) and the entire assembly will slide out. Then simply inspect the condition of the packingmaterial and determine if a new cartridge is needed. If the material is worn out, simply order a new cartridge (WB # 06-930) and install per the instructions supplied. Insert the entire assembly back into the silencer shell and you are done. It’snever been simpler to repack a silencer!For maximum sound intenuation and long life of your silencer shell, we highly recommend that you check the packingmaterial in aluminum silencers at a minimum of 2 month intervals. For carbon fiber silencers, check at 1 month intervals.Though the carbon shell is extremely strong and durable, extreme heat caused by a dissipated packing cartridge cancause it to be damaged.Keep in mind that the life of your silencer packing can vary greatly by your riding conditions and engine state-of-tune.Check often at first. This will then provide you a gauge for future maintenance intervals.LIMITED WARRANTYWhite Brothers warrants its E-Series aluminum silencers and stainless steel megaphones/s-bends/headpipes for a period of one year against workmanship and material failure from dateof purchase and to the original owner. Carbon fiber silencers and titanium headpipes are limited to a period of ninety days.Under the terms of said warranty, White Brothers will repair or replace the defective component at their discretion.

    Dumb White Brothers E Series Spark Arrestor Question!

    Does anyone have an exploded view of the White Brothers E Series Exhaust?

    I'm attempting to get my newly acquired 400ex to be quieter for the trails. I received a box of goodies with the quad and in there is a spark arrestor that is oval shaped like the end of my exhaust. Do I just take off the endcap and add the spark arrestor? Is there a gasket of some sort? Will this help quiet it down (its extremely loud right now and the end is open)?
    I've also ordered the quiet core insert . . will this go on along with the spark arrestor or in replace of?

    Thanks

    is the spark arrestor just like a flat plate with holes drilled around the perimeter or is it like a cone screen type?

    if it's just the flat plate style, take all the screws out and put it right behind the end cap and put the screws back in.

    actually with just the plate style in it it's pretty quiet. if it's that style put it in and see what you think.

    i would say the quiet core would replace the plate style.

    I had the e series and the silencer or w/e is a seriers or rings that direct the exhaust out the sides and the last 1 there is a block off plate.

    Yep, just a flat plate with screw holes. I assume the exhaust escapes through the rings/discs then, correct?

    Alright, got it on and it sounds 100 times better. I think once the quiet core gets here I'll be good to go.

    Also when you get the quiet core, remember that it goes infront of the discs.

    Yea thats how i run mine, its pretty quiet. u probably could run with just the quiet core but i never tried it tho.. Now that i think about it i just might try it.

    Remember from the pipe its: Q/c--discs--flat end cap--tip...
