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

Kawasaki KZ750 Twin Carburetor Installation Manual

Filed Under (Kawasaki) by admin on 25-10-2010

download
The first Kawasaki KZ750 twin was built in 1975 and sold as a 1976 model as a KZ750B1. For the first four years of production (1976-79), the KZ750B1 through B4 shared identical Mikuni BS38 carburetor assemblies. These assemblies are probably the heaviest twin-carb assemblies ever built and have a couple unique features. The biggest oddity is that the Kawasaki version of the BS38 uses a system where both the pilot jet and main jet are screwed into the float bowl. A good bowl gasket is critical because gas is drawn from the jets into the internal passages that lead to the venturi via channels beneath the gasket inside the float chamber. The pilot jets used are standard BS series fare in that they are Mikuni BS30/96 type but the main jets are unique to Kawasaki BS38 carburetor assemblies. They look like very small air jets and are frequently stripped as they require the correct sized small screwdriver to remove

INSTALLATION PROCEDURE Note: All Evolution® “Big Twin” pistons are marked “Front” or “Rear” and come with rings, wrist pins, and locks. • Note: We highly recommend that a dealer or trained mechanic perform the installation of these pistons. Specialized equipment is required for honing and finishing the cylinders to ensure long life of the piston and cylinder assembly. 1. Remove original equipment cylinders from engine. Refer to a shop manual or other reference book for specific steps, if needed. (Note: Care should be taken not to bend the studs or damage the cylinder during removal of the cylinders.) 2. With a small screwdriver, move the wrist pin retainer around to gain access to the tail of the retainer as it lines up with the notch in the bottom of the wrist pin hole. 3. Use a small screwdriver, pick or awl to roll the wrist pin retainer out of its groove. 4. Push wrist pin out and remove piston. 5. Repeat procedure for the other piston. 6. At this point, take cylinders, new pistons, and piston-to-wall clearance specifications to your dealer or machine shop to perform necessary machining operations. • IMPORTANT NOTE (Evolution® and Twin Cam®): The cylinder bore must be machined/honed to provide .0025″ of piston-to-wall clearance. Measure the piston diameter at a point .500″ up from the lower skirt (See Figure 3). 7. Starting with the front cylinder, install new piston rings and one wrist pin retaining clip (Note: Second ring has a dot which must face up when the ring is installed) . 8. Place the piston over the conecting rod, making sure that the intake valve pocket is towards the intake side. (For Evolution ® , see Figure 1. For Twin Cam ® , see Figure 2) . Coat the wrist pin with engine oil and insert it into the piston. Install the second wrist pin retainer into the groove. 9. Lightly coat the piston skirt with engine oil. Place a piston ring compressor over the piston/ring assembly and compress. Place the cylinder over the piston and gently push down until all rings are in the cylinder. Remove the ring compressor, and push the cylinder the rest of the way down. (Note: Be careful not to get oil onto the base gasket.) 10. Place two nuts and washers on opposite corners of the #1 cylinder to hold it down while you repeat the procedure for cylinder #2. 11. Assemble the rest of the engine per factory specifications. Start the engine and let it run at 2000 rpm for about 10 minutes.

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.

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

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)
