In a piston valve, the control of stem and seat leakage is obtained by tightness of the valve sealing rings to the body and valve plug. The bonnet compresses the valve sealing rings against the body and the valve plug. Flexible disc springs automatically assure a tight seal by exerting pressure on the valve sealing rings, keeping them compressed. Opening and Closing the TVS Isolation Valves The isolation valve begins to stop flow when the valve plug enters the lower valve sealing ring. When the isolation valve is completely closed, the valve plug is in contact with the full height of the valve sealing rings, ensuring the best possible seal. In fact, there is no advantage to be gained in torqueing the valve closed. Armstrong recommends that after closing the isolation valves completely, the handwheel should be turned back one half turn. This makes it easy to re-open the valve by avoiding metal to metal seizure. Troubleshooting – Isolation Valves A piston valve will retain its leak tightness for several years without maintenance. In severe service, such as rapid heating and cooling, some field maintenance may be required. Depending on the problem, these simple steps may help: ! ! ! ! ! Isolation Valve leaks, when the valve is closed . First, Check to make sure the valve is actually closed . Check to see if bonnet is seated on the body, if not, tighten the bonnet nuts until the bonnet seats. This recompresses the valve sealing rings against the body and the valve plug. If valve continues to leak, replace the isolation valve assembly

FUEL PUMP The electric fuel pump is mounted at the bottom of the fuel tank, which consists of the armature, magnet, impeller, brush, check valve and relief valve . The ECM controls its ON/OFF operation as controlled under the FUEL PUMP CONTROL SYSTEM . When electrical energy is supplied to the fuel pump, the motor in the pump runs and together with the impel- ler . This causes a pressure difference to occur on both sides of the impeller as there are many grooves around it . Then the fuel is drawn through the inlet port, and with its pressure increased, it is discharged through the outlet port . The fuel pump has a check valve to keep some pressure in the fuel feed hose even when the fuel pump is stopped . Also, the relief valve is equipped in the fuel pump, which releases pressurized fuel to the fuel tank when the outlet of the fuel pressure has increased up to 450 -600 kPa (4.5- 6.0 kgf/cm2,64- 85 psi) . Relief valve Brush , ∎ I,’ Check valve Magnet L Armature When the impeller is driven by the motor, pressure differential occurs between the front part and the rear part of the blade groove as viewed in angular direction due to fluid friction . This process continuously takes place causing fuel pressure to be built up . The pressurized fuel is then let out from the pump chamber and discharged through the motor section and the check valve . FUEL SYSTEM AND THROTTLE BODY 5- 3 Inlet port I I Impeller 5-4 FUEL SYSTEM AND THROTTLE BODY FUEL PRESSURE REGULATOR The fuel pressure regulator consists of the spring and valve . It keeps absolute fuel pressure of 300 kPa (3.0 kgf/cm2,43 psi) to be applied to the injector at all times . When the fuel pressure rises more than 300 kPa (3 .0 kgf/cm2, 43 psi), the fuel pushes the valve in the regulator open and excess fuel returns to the fuel tank . 90 Spring 02 Valve FUEL INJECTOR The fuel injector consists of the solenoid coil, plunger, needle valve and filter . It is an electromagnetic type injection nozzle which injects fuel in the throttle body according to the signal from the ECM. When the solenoid coil of the injector is energized by the ECM, it becomes an electromagnet and attracts the plunger. At the same time, the needle valve incorporated with the plunger opens and the injector which is under the fuel pressure injects fuel in conic dispersion . As the lift stroke of the needle valve of the injector is set constant, the volume of the fuel injected at one time is determined by the length of time during which the solenoid coil is energized (injection time)

ATK 50MX INSTALLATION AND ADJUSTMENT TIPS

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. HM CRX50 / BAJA & ATK 50MX INSTALLATION AND ADJUSTMENT TIPS Continued on next page. #HM50 – 5/27/99 #HM50 – 5/27/99 To Front Valve Mounting channel Spacer Flange Shock eye Top View of Shock Mount 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 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

Before starting to assemble this forward kit on your motorcycle check the packing list to make sure that the kit you received is the correct one for your model motorcycle and that the foot pegs are the style you ordered (billet or ISO). Next check the contents hardware kit P.N.0109-1000 against the packing list for completeness. Installing The Shift Control Photo 1 Remove wires from horn. Remove the two hex head bolts (Save for later installation) that mount the OEM shift controls to your motorcycle. Unthread stock shift rod at trans shift arm, leaving OEM rod end connected to stock shift arm. Using Original Metric hardware, place a drop of Loctite #242 (blue) to the bolt threads and mount the shift control plate to the motorcycle frame, Photo 2. FORWARD CONTROL KIT PM SHIFT CONTROL ASSEMBLY Note Before torquing the shift control mounting bolts down, tighten them snug and look behind the shift control mounting plate to where it contacts the mounting lug on the frame. Make sure it fits squarely to the lug before proceeding further. Torque the two shift control mounting bolts down to 25 ft-lb. Using a 3/8″ x 1″ hex head bolt with a lock and flat washer put a drop of Loctite #242 (blue) on the threads and insert the bolt through the rear of the control mounting plate and attach the foot-peg pivot to it. Tighten the bolt while holding the footpeg pivot so that its hinge is lined up in a 45˚ rear facing angle. Thread supplied shift rod coupler to stock shift rod end at trans arm. Mount the shift pedal to the other end of the shift ro d using a 5/16″ x 1″ socket head screw and Nylocnut . Adjust the transmission shift linkage so that the shift arm on the forward controls and the shift arm on the transmission are parallel. Secure it with the jam nuts. Apply a drop of Loctite #242 (blue) to the threads under the jam nut before tightening see Photo 3 After you have assembled the shift control onto your motorcycle you must align the footpeg. The folding footpeg assembly uses a blind stud to attach the footpeg to the footpeg pivot. Shim washers (3/8″ x .015″) are used on the stud between the footpeg and the pivot, see Photo 4, so that the top surface of the footpeg is correctly aligned for your foot when it is tightened down on the pivot. This is done by setting a couple of shim washers on the footpeg mounting stud “A” and then screwing the footpeg onto the mounting stud, if the footpeg is rotated to far forward then add another shim washer, if not far enough then remove a shim washer. After you have the selected the correct number of shims for your footpeg, disassemble the footpeg and put a drop of Loctite #271 (red) on both ends of the stud and reassemble the footpeg. This will also need to be done on the brake control footpeg. Setting Up the Master Cylinder The master cylinder pushrod return spring and pushrod boot must be installed on the master cylinder before it is assembled onto the forward control mount. The parts are shown in Photo 5: pushrod boot (A), pushrod return spring (B), spring seat washer (C), and master cylinder (D). Place the return spring seat washer into bore of master cylinder so that is sits on top of the piston retaining snap ring. Next set the pushrod return spring on the seat washer and slide the pushrod boot over the return spring now slip the big end of the boot over the flange on the master cylinder so that the ridge on the inside of the boot fits into groove “A” that is machined into the end of the master cylinder flange, see Photo 6. Installing The Brake Control Unplug stock brake light switch at master cylinder. Remove brake line from rear caliper. Remove the existing brake controls from your motorcycle down to the control mounting lug that is welded on to the frame’s right side, see Photo 8. Save Metric hardware for later use.
