Filed Under (TVS) by admin on 29-04-2012

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

Remove tappet assemblies from engine being sure that each one is kept with it’soriginal tappet block. NOTE: This procedure is the preferred method of installation. However, kit can be installed without removing lifters from engine. 2. Remove hydraulic piston retaining wire clip from one assembly at a time. Be careful not to bend wire clip during disassembly. 3. Completely disassemble tappet removing all parts. 4. Thoroughly clean all parts including tappet body. Remove any oil which might prevent hydraulic unit from fully collapsing during adjustment. 5. Insert one spacer from S&S HL 2 Tkit in tappet body. 6. Reassemble tappet in reverse order making sure original parts arereturned to their original positions. See Picture1. 7. Replace wire retaining clip in tappet body. 8. Put tappet back in original tappet block. 9. Repeat Steps 2 through 8 for three remaining tappets. 10. Reassemble engine with modified tappets. 11. Adjust pushrods. NOTE – In all cases engine must be cold and lifter must be at lowest point of travel for pushrod adjustment To prevent accidents, remove ground cable from battery. A. Remove spark plugs. B. Bring piston to TDC on compression stroke in cylinder to be adjusted. Normally both tappets will be at their lowest point of travel. C. Extend pushrod adjustment, collapsing lifter until piston assembly is in contact with HL 2 Tspacer and pushrod is tight. If tappets contain oil, as when pushrods are readjusted after engine has been run, or if all oil was not removed during installation, extend pushrod adjustment until valve is open (about five additional turns of adjusting screw). Allow 5 minutes for hydraulic unit to bleed down. If pushrod can be turned with fingers after bleeding down, lifter is not completely collapsed, and this step must be repeated. NOTE – perform this operation on one cylinder at a time. Do not turn engine until pushrod adjustment is complete. Turning engine while valve is held off the seat could result in valve to valve or valve to piston contact and serious valve train damage. D. Loosen pushrod adjustment until pushrod can be rotated with the fingers with slight drag. NOTE – Shortening adjuster an additional six flats or full turn from zero lash often results in quieter pushrod operation. This provides additional travel for the hydraulic piston assembly, which can improve the ability of the hydraulic unit to maintain zerolash under normal operating conditions. E. Tighten lock nut. F. Follow the same procedure for all four push rods. G. Recheck pushrod adjustment after a few hundred miles. NOTES ● It is a good idea to recheck pushrod adjustment in a new engine as valve train may tighten up due to gasket compression and valve seat wear. ● Upon initial start up after modification, HL 2 Tequipped lifters may be somewhat noisy for 10-20 miles. If lifters are still noisy after 20 miles it is recommended that pushrods be adjusted 1⁄2 turnlooser. See step D

1. Loosen and move the right side floorboard out of the way to ease installation of the exhaust. 2. Perform the following to remove the stock exhaust system. NOTE : You must disconnect and remove the power valve cables as well as unplug the oxygen sensor connector first, then remove the exhaust system and mounting bracket, see Figure 1 for power valve. Loosening the jam nuts on each cable, and disengaging the cable barrels from the power valve pulley disconnect the power valve cables. The power valve, and cables are not needed with the new Cobra exhaust system, leave the solenoid box under the seat in place without the cables. To disconnect the O 2 sensor remove the right rear footpeg and remove the steel plate with hook securing O 2 sensor harness behind it, retain plate for later reinstallation. Remove the socket head screw securing the O 2 sensor harness and bracket to engine case on the right side of the motorcycle, see Figure 2 , unplug the stock male and female connectors, and remove entire exhaust system. Disengage the female O 2 connector from the small bracket, (which was unbolted from engine case), to gain extra harness length, upon reassembly of new Cobra exhaust, the small bracket, (from engine case), will not be reused, unless a closed loop Fi2000 ® (92-1773CL /92-1773CL-50), is to be used, then please refer to those specific instructions. Next remove the oxygen sensor from the stock exhaust and retain for later reinstallation. 3. Install new exhaust-mounting bracket using the stock M10 bolts; tighten to factory specifications, Figure 3. 4. Install the front and rear headpipes on to the motorcycle using the supplied flanges, stock bolts and nuts. NOTE: On the rear headpipe be sure to install the stock flange cover as shown in Figure 4. Make sure the pipes are parallel to each other. DO NOT TIGHTEN. 5. Remove the muffler assembly from the box and slide two supplied 27-61MSC clamps onto the muffler inlets, refer to Figure 5 for alignment. Do not install oxygen sensor at this time, as it will not clear the frame rail during installation of the muffler assembly. 6. Slide the muffler assembly on to the headpipes by tapping on the headpipes by hand as you push the muffler forward making sure the assembly slides as far forward as possible. Secure the muffler assembly to the mounting bracket using the supplied 5/16-18 bolts but DO NOT TIGHTEN. Install the oxygen sensor at this time, by inserting it between the right frame rail, and engine case, tighten securely once installed. 7.

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

Stand Installation. Locate the four mounting holes on the frame that correspond with the holes in the centerstand. Slide the front of the centerstand up into the frame and align the large bolt holes with those in the frame. Install the (2) 7/16″ x 1″ bolts with washers thru the frame and centerstand. Install the (2) 7/16″ nuts and make finger tight. (on California models the fuel tank vent canister must be removed and the hoses bypassed see note below) Pivot the rear of the centerstand up to align the (2) smaller holes in the stand with those in the frame. Insert a phillips screwdriver into one of the (2) remaining mounting holes and pry the other hole into alignment. Install one of the ¼” x ¾” bolt with a washer from the top down thru the frame and centerstand. Install the lock nut finger tight. Remove the screwdriver and install the remaining ¼”x¾” bolt washer and nut. Tighten the ¼ ” bolts securely 10-12 ft. lbs., then tighten the 7/16″ bolts securely 20-24 ft. lbs. 2. Stop Bumper Installation. Next install the centerstand-stop bumper and bracket onto the frame. Locate the bolt “A” in photo #1. Notice there is another 10 mm bolt just below it. Remove the lower bolt. Attach the bumper bracket to this hole using the longer bolt and washer supplied. The leg of the bracket with the bumper should face inward towards the center of the motorcycle. Adjust the height of the bracket to keep the pedal arm 3/8″ to ½” from the bottom of the exhaust pipe. Tighten securely. 3. Emissions Valve Relocation. You will notice that the right leg of the stand near the foot comes in contact with the emissions valve. The valve needs to be moved outward or to the right as you are sitting on the motorcycle approximately ¾”. This is done as follows: Remove the (2) 10 mm bolts holding the emission valve and bracket to the frame. See photo #2. With the hoses still attached pull the valve down to gain access to the (3) allen screws. Remove the (3) allen screws and (2) nuts holding the bracket to the valve, turn the bracket over and re-assemble the valve onto the bracket as shown in photo #3. Re-install the valve onto the frame. You may need to rotate the hose clamp clips out of the way and/or bend the entire valve bracket assembly outward slightly to gain clearance between the centerstand leg and foot. 4. Using Your New Centerstand. To put the motorcycle up onto the centerstand, hold the left handle bar and saddlebag guard rail. Using the ball of your right foot, lower the stand to the ground. Rock the motorcycle from side to side slightly until you feel both feet of the stand touching the ground. Now, put all of your weight on to the centerstand pedal (stand on it). Pull up and back on the grab rail using a rocking motion to rock the motorcycle up on to the stand. Remember it is a matter of using your body weight and leverage not lifting! 5. Getting the Bike Down off the Centerstand. Holding the left handle bar and saddlebag guardrail, firmly rock the motorcycle off the centerstand. You can also rock it off while sitting on the motorcycle.
