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

MAINTENANCE AND TUNE-UP PRO- CEDURES This section describes the servicing procedures for each item of the Periodic Maintenance requirements. AIR CLEANER I Inspect every 6 000 km (4 000 miles, 6 months) and replace every 18 000 km (11 000 miles, 18 months) . • * Remove the seat. (LF6-7) • * Lift and support the feul tank . (C-74-65) • * Remove the air cleaner box cap O. • * Remove the air cleaner element O. • * Carefully use air hose to blow the dust from the cleaner ele- ment. CAUTION Always use air pressure on the throttle body side of the air cleaner element . If air pressure is used on the other side, dirt will be forced into the pores of the air cleaner element thus restricting air flow through the air cleaner element . PERIODIC MAINTENANCE 2-5 2-6PERIODIC MAINTENANCE • * Reinstall the cleaned or new air cleaner element in the reverse order of removal . CAUTION If driving under dusty condition, clean the air cleaner element more frequently. The surest way to accelerate engine wear is to use the engine without the element or to use a ruptured element. Make sure that the air cleaner is in good condition at all times. Life of the engine depends largely on this component! NOTE: When cleaning the air cleaner element, drain water from the air cleaner by removing the drain plug . SPARK PLUG Inspect every 6 000 km (4 000 miles, 6 months) and replace every 12 000 km (7 500 miles, 12 months) . No. 1 (FRONT) SPARK PLUG REMOVAL • * Remove the radiator mounting bolt O. • * Move the radiator forward. • * Remove the spark plug cap O. NOTE: Be careful not to damage the radiator fins . A WARNING The hot radiator and the hot engine can burn you . Wait until the radiator and the engine are cool enough to touch . • * Remove the spark plug with a spark plug wrench. 1 6 I It No. 2 (REAR) SPARK PLUG REMOVAL • * Remove the seat. (r–,-6-7) • * Lift and support the fuel tank .

HEAT RANGE • * Check to see the heat range of the plug . CARBON DEPOSIT •Check to see if there are carbon deposits on the plugs . If carbon is deposited, remove it with a spark plug cleaner machine or carefully using a tool with a pointed end . SPARK PLUG GAP • * Measure the plug gap with a thickness gauge . If out of specification, adjust it to the following gap . 09900-20803 : Thickness gauge Spark plug gap OA Standard: 0.6 – 0 .7 mm (0.024 -0.028 in) ELECTRODES CONDITION •Check to see the worn or burnt condition of the electrodes . If it is extremely worn or burnt, replace the plug . And also replace the plug if it has a broken insulator, damaged thread . CAUTION Confirm the thread size and reach when replacing the plug.

Clean the air filter Pull off the right-hand side panel and remove the two nuts which secure the air filter cover. Withdraw the cover, checking that the sealing gasket is in good condition, pull out the retaining spring and withdraw the element assembly. Peel off the inner and outer foam sleeves. Wash all components in white spirit (Stoddard solvent) or in warm water and detergent and dry them thoroughly. Soak the foam sleeves in the specified oil, then squeeze them gently (do not wring them out or they will be damaged) to expel all surplus oil. Refit the sleeves to the element frame. On reassembly ensure that all components are correctly fitted so that unfiltered air cannot bypass the element. 2 Check the spark plug Remove the spark plug cap, unscrew the plug and check its condition, comparing it with the photographs on page 65. If it is badly worn or fouled it must be renewed. If it is fit for further service check the gap and reset it if necessary, as described in Chapter 3.8. 3 Check the valve clearances It is important that the correct valve clearance is maintained. A small amount of free play is designed into the valve train to allow for expansion of the various components. If the setting deviates greatly from that specified, a marked drop in performance will be evident. In the case of the clearance becoming too great, it will be found that valve operation will be noisy, and performance will drop off as a result of the valves not opening fully. If on the other hand, the clearance is too small the valves may not close completely. This will not only cause loss of compression, but will also cause the valves to burn out very quickly. In extreme cases, a valve head may strike the piston crown, causing extensive damage to the engine. The clearances should be checked and adjusted with a cold engine. Place the machine on its centre stand and remove the rocker cover, taking care not to damage the 0 ring. Remove the gearchange pedal and the left-hand outer cover to expose the generator rotor. Remove plug and allow old oil to drain Remove the spark plug, then slowly rotate the engine anticlockwise by way of the generator rotor, watching the inlet valve. When it has opened and closed again (sunk down and risen up to its original position), rotate the engine further until the T mark on the rotor periphery aligns exactly with the raised index mark which is positioned between 12 and 1 o’clock (from the crankshaft) on the generator stator. The engine will then be in the correct position for checking the valve clearances, namely at Top Dead Centre (TDC) on the compression stroke; check that there is free play at both rockers. Using a 0.08 mm (0.003 in) feeler gauge, check the clearance between the top of each valve stem and its corresponding rocker. The feeler gauge must be a light sliding fit, with the rocker and valve stem just nipping it. If necessary, slacken the locknut, and turn the small square-headed adjuster to obtain the correct setting. Tighten the locknut, holding the adjuster at the same time to prevent it from moving. Finally, recheck the setting and then repeat the procedure on the other rocker. 4 Check the contact breaker points and ignition timing Note: since the generator stator plate is located by its countersunk retaining screws, the ignition timing can only be altered by opening or closing the contact breaker gap; therefore both operations are described as one. The full procedure is given here for ease of reference, but if the points are found to be in good condition and if the gap has not altered or is within the tolerance, then the ignition timing will be sufficiently accurate and there will be no need to carry out the full check. First remove the gearchange pedal, the left-hand outer cover, the spark plug and the left-hand side panel

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)

Find the guide plug.bn The guide plug is shown in the shop manual with the engine removed from the frame and the left crankcase cover removed. (You’ll find this illustration in the “ELECTRIC STARTER/STARTER CLUTCH” chapter in the “STARTER DRIVEN GEAR/STARTER CLUTCH REMOVAL” section.) It’s a little bit harder to find it on the bike. Start by following the yardstick to see where the guide plug is on my bike. To find it on your bike, lie on the ground (or, preferably a mechanics creeper) next to the bike (without the yardstick) and peek under the shift lever and over the frame There it is, just barely visible from the side of the bike. Here’s what a new one looks like: 2. Clean the guide plug and crankcase. From the front of the bike, clean the guide plug and crankcase with brake cleaner in a VERY focused spray. Let the cleaner evaporate before moving to the next step. Page 4 Rev: Draft 5/20/2007 Page 4 of 5 3. Reposition the guide plug. a. From the side of the bike, use the yardstick (or a long screwdriver if you prefer) to gently push the guide plug back into the crankcase. (Note the JB Weld from the previous patch operation.) b. From the front of the bike, gently push upward on the bottom of the upper tab (as shown below) or the bottom of the forward tab to rotate the guide plug into the proper position while maintaining pressure with the yardstick
