MULTI-RATE SPRINGS AND THE ARS SYSTEM Depending on the application dual–rate springs are fitted on the shocks. Dual-rate springs are just that– a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs collapse they produce a soft, or initial, rate. The spring set will maintain this initial rate until the short spring stops compressing. At that point, the spring rate “crosses over” to the stiffer, or final, rate. This multi-rate system allows a soft initial rate for comfort on small bumps, but has the capability of soaking up the big pot-holes and other off road hazards. ARS stands for Adjustable Rate Suspension. ARS is available on some dual-rate spring 4-wheel ATV shocks. ARS differs from spring preload. The ARS system allows the rider to increase or decrease the load-carrying capacity of the shocks by turning a lever. Depending on the application and spring set, the rider can increase the load capacity of the shocks up to 50 percent. The average preloader that makes a half-inch increase in preload will HONDA 450E/S MOUNTING & ARS ADJUSTMENT INSTRUCTIONS Continued on next page. #TRX450 – 5/28/99 #TRX450 – 5/28/99 Fig. 1. Front shock installation. Note that the shock body is at the top with the shaft pointing down. ARS shown is in the unloaded position. Fig. 2. Rear shock mounting with ARS. Position the lever so that it will not come in contact with any vehicle parts around it. The cup can be rotated to reposition the lever if necessary.
increase the capacity of the shocks to only about 5 to 10 percent. ARS allows the shocks to be correct for solo riding, but still handle the increased weight of an added load. ARS can also be employed to stiffen the rates for aggressive riding. The ARS system consists of an indexing lever and a stepped cup that contains the short spring of the dual- rate. The position of the lever in relation to the steps in the cup determines how long the spring set remains on the soft, or initial, spring rate. On most ARS applications, four positions can be selected from full stiff to full soft. Indexing is done in a matter of seconds by rotating the lever or the cup by hand. Indexing the cup to the lever is usually preferable to avoid interference. Adjustment of the ARS system should only be made while the vehicle is unloaded to reduce the load on the springs. NOTE: It is important to make sure that a step in the cup is positioned directly over the tang on the lever. This will prevent damage to the cup and/or lever that can be caused by making partial contact between the tang and a step. In addition, make sure that the lever will not contact any vehicle parts around it, as the suspension moves up. TUNING TIPS—The “softest” setting on the ARS does not mean that the ride will be the most comfortable at that setting. It means that this is the softest spring setting which would be employed on smooth trails or without a load. Excessive suspension bottoming caused by rough conditions or by the addition of a large load will cause a harsh ride when the shock is adjusted to this setting. To eliminate this bottoming, adjust the ARS to the stiffer positions for a more comfortable ride. Hence, sometimes “stiffer is softer.” NITROGEN PRESSURES IN EMULSION SHOCKS

Place jack under center on the ATV front end and lift until front wheels clear the ground. Be careful to support ATV properly so that it is secure, but so that the A-arms and shocks can droop to full extension. 2. Remove front wheels and shocks. 3. Using a shock spring compressor, compress the spring on the shock and remove the spring retaining ring.
CAUTION: The spring is installed under tension. Failure to use a shock spring compressor could cause loss of control of the spring, which could unload rapidly causing bodily injury. If you do not have a shock spring compressor you should acquire one or take it to a dealer or professional mechanic for installation of the stiffeners. 4. Remove the spring. 5. Insert the smaller front spring stiffener onto the shock with the lip of the spring stop, on the shock, mating into the recessed portion of the spring stiffener. 6. Slide the spring back onto the shock and it should rest on the lip of the spring stiffener.
7. Reattach the spring retaining ring. 8. Repeat steps for the opposite side. Once springs are complete reattach the top of the shock to the top shock mount on the ATV and the spring stiffener will be closest to the A-arm. 9. Take two of the “L” brackets and connect them to the bottom of the shock, the part that connects to the A-arms. 10. There is a top and bottom to the “L” bracket. See the diagram

PRELOAD ADJUSTMENT— On some Works shocks a threaded preload is standard. This allows the adjustment of the ride height of the motorcycle. The preload is changed by turning a threaded nut down towards the spring (higher ride height) or up away from the spring (lower ride height). The nut is a right-hand thread. CHECKING RIDE HEIGHT— 1. With the bike unloaded on the side stand and the shock fully extended, have an assistant measure from a point at the axle (center point) to a point on the frame, fender or bodywork directly above it. Record this measurement. 2. With the bike off the stand and the rider in the seat, bounce on the suspension and let the bike settle. Have the assistant measure from the same two points. Subtract the second measurement from the first.

The flange on the shock bushing must face toward the spacer. The valve should point toward the front of the bike Fig. 1 Top view of upper shock mount. The flange on the shock bushing must face toward the spacer. The valve should point toward the front of the bike 3. The amount of settle, or “sag” is a function of the wheel travel. It should only be between 1/4 and 1/3 of the total travel. 4. If the difference is less than the minimum, reduce the spring preload. Measure the distance again starting with Step 2. Adjust again if necessary. 5. If the difference is more than the maximum, increase the spring preload. Measure the distance again starting with Step 2. Adjust again if necessary. Note: If the ride height is too low, the shock will bottom unnecessarily, resulting in a harsh ride. If the ride height is too high, the shock will “top out” too easily when rebounding from a bump or under hard deceleration. NITROGEN PRESSURES IN EMULSION SHOCKS CAUTION: The pressure in these shocks cannot successfully be checked. Concerns with the gauge volume and the gas volume in the shock body create a situation where you cannot accurately determine what pressure was in the shock. In addition when the pressure is lowered (i.e. checking the pressure) the gas and some of the shock oil escapes into the gauge. It is possible to lose a large percentage of the shock oil by depressing the core of a charged shock to the atmosphere. Please note that in order to check the pressure, some of the gas must escape and fill the gauge assembly. The volume of the gas pocket is about half the size of your thumb, so a very small volume change results in a large pressure drop. Because the gauges’ volumes vary, it is not possible to deduce the actual pressure in the shock prior to attaching the gauge. Therefore it is imperative that any attempt to check pressure be accompanied by the capability of refilling the shock. In other words: If you don’t have a nitrogen source handy, don’t check the pressure! PRESSURIZING EMULSION SHOCKS The pressure setting for Works gas shocks is 250 p.s.i. of dry nitrogen. To pressurize a shock with some residual pressure in it, bring the gauge manifold up to 250 p.s.i. and depress the core with the T-handle. This will either equalize the pressure or refill the shock without transferring oil from the shock into the gauge assembly. The best gauges for this purpose screw on to the valve and incorporate a T-handled core depressor to isolate the shock from the gauge. This allows a leak-free separation once the desired pressure is reached. For simplified operation, an extra valve is provided for the filling apparatus, allowing pressure adjustment with the gauge in place. Works offers a suitable gauge and filling manifold. Most motorcycle shops that deal with dirt bikes can pressurize the shock

Installation: 1. Remove the fork springs according to the OEM Owner’s Manual. 2. Check/adjust fork oil level and weight according to OEM Specifications. Caution: Most inverted forks will not require the use of any shim washers or spacers. In cases where use is necessary with the twin chamber style fork, the shims must be placed at the bottom of the spring. Most conventional forks (non-inverted) will use shim washers or spacers at the top of the fork spring. 3. Install Factory Connection fork springs and refer to OEM Owner’s Manual for proper assembly procedures. 4. Be sure to double check all fasteners. Note: Most modern day forks require special tools for disassembly and assembly of the components. Examples : Showa 47/49mm Twin Chamber, KYB 48mm Twin Chamber, WP 07 SX Models/SXS Components. Installing fork springs is an intricate process that should be performed with extreme care by a qualified suspension technician. Failure to install the springs correctly could cause damage to one or more components of the fork. This damage, although not readily apparent, could lead to unexpected failure or rider injury. Factory Connection manufactures models specific fork springs. Installation of a Factory Connection spring not designed for your motorcycle may result in unexpected failure and rider injury. Please consult your Factory Connection spring dealer or call Factory Connection directly if you are unsure about a spring/or springs. 1. Factory Connection’s Limited Lifetime Warranty Factory Connection warrants, to the original retail purchaser (“consumer”) who retains ownership of the vehicle on which the suspension spring(s) (“products(s)”) was originally installed, all suspension springs for life against factory defects in material and workmanship (other than defects in finish) when used under normal use and operating conditions. 2. Your Remedy Upon verification of warranty coverage, Factory Connection at its option will replace defective or prematurely worn-out product (s), without charge, or refund the purchase price of the products(s). This is the Consumer’s sole and exclusive remedy for any loss or damage, however arising, due to a nonconformity or defect in the product(s). 3. Warranty Claim Procedure To make claim under this warranty, the consumer should contact the Factory Connection dealer or Factory Connection where the product(s) was purchased. Factory Connection reserves the right to test the returned product(s) to evaluate the nonconformity or possible defect.

1. Remove fork springs according to instructions contained in your shop manual. For maximum performance we highly recommend that the forks be thoroughly cleaned, inspected and new fork oil installed. Note: If your motorcycle comes equipped with two fork springs in each leg (long & short), remove and discard both springs and the flat washer between the springs. If a stock spacer exits, remove it. If there is a short spring on the damper rod, do not remove it! 2. Use the recommended fork oil viscosity as noted in your owners manual with the following exceptions: GL1100 20 weight, GL1200/1500 15 weight required. See fine tuning for more in- formation. Fork oil level/volume should be checked according to the steps outlined in your authorized shop manual. Measurement of your fork oil by level is the preferred method. However, some manuals only specify a volume measurement. Due to the design of a progressive wound fork spring it will displace more oil thus requiring a maximum oil level of 5.5″ (140mm). Caution: This is not a recommendation, it is only a precautionary statement. If your manual specifies an oil level higher than 5.5″ (140mm) set the oil level at 5.5″ (140mm). (Oil level is the distance from the top of the fork tube to the top of the oil with the fork completely collapsed and the fork spring removed see figure 1.) This measurement can be made by using either one of the Progressive Suspension Fork Oil Level Adjusters (FOL-1 or FOL-2). 3. Install your new fork springs into the forks. Mechanically, it makes no difference which way the springs are installed. Some manuals will state; install the spring with the close wound end towards the bottom. This is done because sometimes there will be less spring noise. The springs will perform exactly the same regardless of which direction they are placed. Check the spacer length requirement for your motorcycle in the enclosed supplement. If not listed, you must calculate the pre-load. What is pre-load? Pre-load is the distance the spring compresses when the fork cap is installed. You may or may not utilize a spacer to achieve proper pre-load. The spacer in itself is not “pre-load”. It just helps to achieve it. Why is pre-load important? It determines the proper ride height which in turn affects how the bike handles.

1. Support the motorcycle so the front wheel is off the ground. Next remove the front wheel and fender. Remove the fork cap nuts and loosen the lower triple clamp pinch bolts. Remove the front brake caliper. Some models have a tapered end to the fork tube. Extra effort will be required to remove the tube from the crown. Loosen the top fork cap 1 to 2 revolutions. Use a soft wood block or similar tool (that will not mark fork cap finish) and tap down with mallet to loosen fork tube from its tapered fit in top steering crown. Make sure fork pinch bolts are loose. To completely remove fork of this style, unscrew the fork cap entirely. 2. Slide both fork assemblies out of the triple clamps. Unscrew the top fork tube plugs. Remove the plugs and fork springs. CAUTION: Fork caps are under spring pressure and could cause serious injury. Drain the fork oil by turning the fork assemblys upside-down. 3. Next, bottom the fork tube into the fork leg. DO NOT extend the tube while you remove the allen bolt on the bottom of the fork leg. Turn the assembly upside-down and shake the damper rod and rebound spring out of the fork assembly. Again, DO NOT extend the tube during this. Extending the tube could dislodge the internal bottoming cone, which fits on the end of the damping rod, making it very difficult to reinstall the damper rod without complete fork disassembly. 4. FOR 1″ REDUCTION IN FORK LENGTH: You must first measure the length of the O.E.M. rebound spring. Depending on the model of the motorcycle, the length will either be 1″ or 2″ long. A. If you currently have a 1″ rebound spring, you need to replace it with the 2″ long LA Choppers rebound spring (included in the kit), then reinstall the damper rod in the fork tube. B. If you currently have a 2″ rebound spring, you will need to add the 1″ long spacer, then reinstall the damper rod in the fork tube.
