throttle linkage with no cable modification. S&S Super E and G carb kits for 1936 to 1989 Big Twins contain a throttle cable guide (11-2339) designed for butterfly type throttle cables, and kits for 1990 and later Big Twins contain a taller throttle cable guide (11-2338) designed for CV type throttle cables. See Picture 2. The two throttle cable guides are interchangeable on the carburetor body, and can be changed very easily to update older carburetors or to accommodate custom throttle cables which are not stock for a particular year chassis. 1981 to Present Sportster Models Stock Sportster models from 1981 to 1987 have two cable throttle system designed for butterfly type carburetors. Sportsters from 1988 to present have a two cable throttle system designed for use with the stock constant velocity (CV) type carburetor. Since the taller #11-2338 cable guide bracket can not be used on a Sportster chassis due to insufficient frame clearance, throttle cables on Sportsters originally equipped with a CV type carburetor must be changed to butterfly style cables. S&S can supply the correct style throttle cables. See S&S Throttle Cable Application Chart.

S&S Throttle Kits S&S throttle kits fit 1″ handlebars and can be used on most chassis. (An adapter sleeve is available for use with earlier, 7 ⁄ 8 ” OEM handlebars originally equipped with internal throttle cable.) Barrel fittings on S&S cables readily “plug in” to S&S Super E, G, and stock H-D 1981-’90 butterfly type carb throttle linkage. Kits include one opening and one closing side cable, left and right grips, and handlebar clamps. Kits with 36″, 39″, 42″, or 48″ length cables are available. Length specified refers to overall cable length. Vinyl covered outer housing is 4″ shorter than overall length

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) .

REMOVAL To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect negative (-) battery cable before proceeding. (00048a) 1. Disconnect battery cables, negative (-) cable first or remove the main fuse following the instructions in the service manual. NOTE When performing cable disassembly procedures, make careful notes as to the existing cable routing. Pay special attention to existing cable strap locations before removing so new straps can be placed into the same locations. Do not remove or install the master cylinder assembly without first positioning a 5/32-inch (4 mm) thick insert between the brake lever and lever bracket. Removing or installing the master cylinder assembly without the insert in place may result in damage to the rubber boot and plunger on the front stoplight switch. (00324a) 2. See Figure 1. Place the cardboard insert between the brake lever and lever bracket. 3. See Figure 2. Loosen cable adjuster jam nuts. Turn cable adjusters in until they are as short as possible. This will provide enough slack for easy removal. 4. Remove the right upper and lower switch housing screws INSTALLATION Throttle and Idle Cable Installation 1. See Figure 3. Apply graphite lightly to the throttle grip inside the switch housing and on the throttle end of the handlebar. NOTE The throttle control cable has a larger diameter retaining ring crimped to the cable end than does the idle control cable. For assembly, apply a drop of light oil on the retaining rings of the crimped inserts. 2. See Figure 7. Push the throttle cable housing and retaining ring into the larger hole of the switch housing, located in front of the tension adjuster screw. 3. Push the idle cable housing and retaining ring into the smaller hole of the switch housing, located behind the tension adjuster screw. 4. Push the throttle and idle control cable housings into the lower switch housing until each snaps into place. NOTE For models not equipped with factory-installed cruise control, if the friction shoe has fallen out or become dislodged, install the shoe with the concave side facing up and position it so the pin hole is over the point of the adjuster screw. 5. Push the throttle control grip over the end of the right handlebar until it bottoms against the closed end. Rotate the grip until the ferrule notches are at the top. To prevent binding, pull the grip back about 0.12 inch (3.2 mm). 6. See Figure 3. Position the lower switch housing beneath the throttle control grip. Install two brass ferrules (Item 3, Figure 11) from this kit onto cables, seating the ferrules in their respective notches on the throttle control grip. The cables must be captured in the grooves molded into the grip. 7. Position the upper switch housing over the handlebar and lower switch housing. Route the wire harness conduit through the depression at the bottom of the handlebar. 8. Tighten the upper and lower switch housing screws finger- tight. 9. Position the brake lever/master cylinder assembly inboard of the switch housing assembly, engaging the tab on the lower switch housing in the groove at the top of the brake lever bracket. 10. Align the holes in the handlebar clamp with those in the master cylinder housing and tighten the lower screw and flat washer finger-tight. Position for rider comfort.

1. Using a sharp knife, remove the rubber from your current grip by carefully cutting it away from the existing plastic throttle sleeve. The rubber that is adhered to the plastic sleeve must be ” shaved” resulting in a smooth plastic sleeve with no rubber. 2. Apply glue to the throttle sleeve. Use about 1/4 of the tube of glue on each side. Most of the glue should be applied to the end of the sleeve away form the throttle housing. 3. Slide the grip on to the throttle sleeve with one strong push. Use a rubber mallet if needed. Be sure not to get any of the glue into the space between the throttle sleeve and the throttle housing as well as the space between the throttle sleeve and the handlebar. *Wipe up any excess glue immediately

Remove the stock fuel induction system, including the manifold and disconnecting all wire connections. It is up to the technician as to whether the gas tank should be removed or just raised up in the rear. Picture 1 2- You will need to disassemble the stock induction system to remove the pre-listed parts for re-use. 3- Verify the new manifold size is appropriate for your motorcycle by sliding it in place. Picture 2 Picture 3 4 5- Slide the MAP sensor in place, being sure not to pinch the orange rubber seal—some clean engine oil may make this easier. Install the cable guide and verify it is aligned with the throttle cable actuator. Once alignment is satisfactory, apply Loctite® 222 to the 10-24 x 1/4″ screws and tighten to 18-22 in-lbs. 4- Install the new O-ring into the throttle body. A light film of clean engine oil can be used to help hold the O-ring in place. Align the manifold to the throttle body, use purple 222 Loctite® on the 10-24 x 1″ socket-head assembly screws (with flat washers) and tighten them to 35-40 in-lbs. 6- Using the new S&S® supplied gasket, slide the S&S supplied intake air temperature (IAT) sensor in place. Use Loctite 222 on the T10 Torx button head M3 x .5 x 10mm screws and tighten to 6-8 in-lbs. Picture 4 Picture 5 Picture 6 5 7- For the stock throttle position sensor attach the “C” shaped spacer to the end of the throttle shaft, put a 4mm flat washer on each T20 Torx button head M4 x .7 x 12mm screw, apply some Loctite® 222 and torque screws to 18-23 in-lbs. 8- Install the new O-ring on the IAC motor. Lubricate the OD of the O-ring with a light film of clean engine oil. Put a 4mm flat washer on each T20 Torx button head M4 x .7 x 12mm screw, coat the threads with Loctite 222. Install the IAC motor and tighten the screws to 18-23 in-lbs. 9- Partially install the fuel injectors in the fuel rail. Be sure to orient the black O-rings to the rail and align the clocking tabs with their holes. It may be helpful to lubricate the O-rings with clean engine oil. See Picture 9. NOTE : These are special O-rings that seal pressurized gasoline. If you see one with damage or an abrasion—replace it immediately. Picture 7 Picture 8 Picture 9 6 10- Connect the Injectors to the manifold with a light squeezing action. Lubricate the O-rings with clean engine oil. Once in place, use Loctite® 222 on the threads of two 8-32 x 5/8″ slotted panhead screws and tighten to 15-20 in-lbs. 11- Install the backing washer and O-ring on the fuel supply tube. Lubricate the O-ring with clean engine oil. When the tube is in place, position the Y-shaped clip on the fuel rail and tighten the Loctite 222 coated T20 Torx button head M4 x 7 x 12mm screw to 18-23 in-lbs – Gently push the injectors downward toward the manifold to increase clearance for connecting the wire connectors. Cut the existing injector connectors from the motorcycle harness. Slide the sleeveing onto the injector harness. Slide heat shrink tubing on to each wire of the injector harness wires. Crimp the butt splices to the motorcycle harness. Move the heat shrinks over the splices and shrink with a heat gun. Slide the sleeve into place. Picture 10 Picture 11a Picture 11b Picture 12 Picture 12a 7 13- Put the stock manifold flanges on the manifold. YOU MUST USE THE S&S® RUBBER GASKETS ON THEM. Be sure to orient the tapered end towards the manifold and the flat end to the heads. 14- Hold the manifold up in its basic mounting position and connect all of the wiring harness connectors at this time. Install the manifold using the stock mounting flange bolts (from the primary side of the motorcycle) coated with Loctite® 242 and the new S&S cam side screws (1/4″ socket head, 5/16-18 x 3/4″). If a screw longer than 3/4″ is used, damage to the heads will result. Lightly snug all four manifold mounting bolts but DO NOT TIGHTEN AT THIS TIME. Connect the throttle cables and cruise control bracket (if applicable) at this time. NOTE: The Harley-Davidson® service manual for your model motorcycle will be helpful during this step. 15- Install the breather system now. On 4.00-inch bore or smaller engines the breather uses banjo fittings with hollow bolts and connects across the heads to the intake with a T-hose. This hose will need to be trimmed and have spring clamps attached as shown in photo. Torque the hollow bolts to 10-12 ft-lbs. On 41/8-inch bore or larger engines, install the sharp bent hose on the rear head and install the check valve with the white end towards the head. Mount the other hose on the black end of the check valve and connect it to the throttle body using spring clamps to secure the connections. Picture 13 Picture 14 Picture 15 8 16- Once the breathers are secure, install the fuel line per the factory service manual you are working with. Connect the battery and verify the fuel pump turns on to pressurize the system and there are no gas leaks, but DO NOT START THE ENGINE. At this time, PC software may also be used to verify sensor readings and adjust the throttle position sensor voltage if necessary. 17- Install two 242 Loctite® coated pipe plugs (included in kit) in the air cleaner backplate as shown in Picture 16. Torque to 35-45 in-lbs. Also, two pan screws coated with Loctite® 222 must be installed in the backplate in place of the enrichment device. See Picture 16a. Torque them to 12-18 in-lbs. Failure to install these screws could allow dirt and debris into the intake system. 18- Use a new gasket on the backplate and put it in place noting the number of shims required. Once you select the appropriate shims (included) mount the backing plate to the engine but DO NOT INSTALL THE SCREWS YET

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)

Filed Under (Tips and Review) by admin on 19-11-2010

download
Throttle Body Assembly (TBA) — The throttle body assembly (also called air valve), controls the airflow to the engine through one, two or four butterfly valves and provides valve position feedback via the throttle position sensor. Rotating the throttle lever to open or close the passage into the intake manifold controls the airflow to the engine. The accelerator pedal controls the throttle lever position. Other functions of the throttle body are idle bypass air control via the idle air control valve, coolant heat for avoiding icing conditions, vacuum signals for the ancillaries and the sensors. FUEL INJECTOR — There are basically three approaches in delivering the fuel to the engine: • Above the throttle plate as in throttle body injection • In the intake port toward the intake valves as in multi-port injection or central multi-port injection. • Directly into the combustion chamber as in gasoline direct injection systems (GDI). The fuel injector is continuously supplied with pressurized fuel from the electric fuel pump. The pressure across the metering orifice of the injector is maintained constant by the fuel pressure regulator. The fuel injector is an electromagnetic valve that when driven by the ECU delivers a metered quantity of fuel into the intake manifold (or combustion chamber in the GDI system). The ECU controls the fuel flow by pulse width modulation. The time the injector is driven into an open condition is determined by the following sensor inputs: • Engine RPM • Throttle position (TPS) • Manifold absolute pressure or mass air flow • Engine coolant temperature • Oxygen sensor feedback voltage • Intake air charge temperature • Battery voltage CENTRAL POINT INJECTION SYSTEM (CPI) — Electronic fuel Injection system consisting on a single fuel injector mounted in the throttle body. DIGITAL FUEL INJECTION (DEFI OR DFI) — Electronic fuel injection system controlled by digital microprocessors as opposed to earlier systems that were of analog design. The analog input signals to the microprocessor are converted from analog to digital before being processed.
