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

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

Remove Old Carburetor WARNINGS ● Gasoline is extremely flammable and explosive under certain conditions. Do not smoke around gasoline. Gasoline fumes are toxic when inhaled. Perform installation in a well ventilated area away from open flames or sparks. Any gasoline leak or spill constitutes a health and fire hazard. ● If motorcycle has been running, wait until engine and exhaust have cooled to avoid getting burned during installation. ● Electrical sparks can ignite explosive gasoline fumes. Failure to disconnect battery while working on motorcycle can also result in inadvertent engagement of starter and personal injury. A. Shut off fuel petcock and disconnect battery. B. Remove air cleaner assembly. Drain fuel from existing carburetor. Remove carburetor, manifold, choke cable and any carburetor mounting hardware NOTE – Removing and tightening hard to reach Allen bolts such as carb-manifold mounting bolts and V2 manifold flange bolts can be greatly simplified by the use of Allen ball-end drivers. These tools are available at most automotive and tool supply houses. See Picture 9. Additionally, Performance Plus of Evansville, Indiana, produces a hex wrench specially modified for accessibility of V 2 manifold bolts. Call 812-963-8854 for further information. As alternative, standard hex wrench can be shortened for convenience. NOTE – Some Buell motorcycles have a breather fitting with 90° elbow on rear head. Due to proximity of frame, elbow must be removed before fitting can be taken off engine. Loosen fitting and rotate to position convenient for cutting elbow. Secure fitting by tightening against cylinder head. Elbow may be inaccessible to hacksaw. In most instances, a die grinder with cutoff wheel will remove elbow with little difficulty. If die grinder is unavailable, grasp elbow firmly with pliers and snap off, then remove fitting. CAUTION – Extreme care must be taken to prevent metal chips from entering engine when elbow is removed. S&S recommends packing breather fitting with gease before removing elbow. Metal chips inside engine will cause extensive damage. Installer bears all responsibility for containment of chips and other debris. Picture 2 Picture 4 Picture 3

motorcycle can be kickstarted with the transmission in gear by disengaging the clutch before operating the kickstarter. Check the engine oil, transmission oil and coolant levels before starting the engine (page 21, 23, 24). Cold Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. If the temperature is 35°C (95°F) or below, pull the choke knob fully out. 4. If the temperature is below 0°C (32°F), open the throttle two or three times. (The engine requires a richer mixture for starting in cold weather. When the throttle is so opened, the accelerator pump will feed extra fuel to the cylinder, thereby facilitating starting in cold weather.) 5. With the throttle closed, operate the kickstarter starting from the top of the kickstarter stroke, kick through to the bottom with a rapid, continuous motion. (Do not open the throttle, As the carburetor is equipped with an accelerator pump, excessive fuel will be charged into the engine, and the spark plug will be fouled if the throttle is opened and closed repeatedly. Excessive fuel in the engine makes kick- starting difficult.) 6. About a minute after the engine starts, push the choke knob back all the way to fully OFF. If idling is unstable, open the throttle slightly. (1) FUEL FILL CAP (2) BREATHER TUBE WARNING (1) FUEL VALVE (2) CHOKE KNOB Warm Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. Pull the hot start lever and kick-start the engine. (Do not open the throttle.) 4. As soon as the engine starts, release the hot start lever 1. Shift the transmission into neutral. 2. Pull the hot start lever and kick-start the engine. (Do not open the throttle.) 3. As soon as the engine starts, release the hot start lever. Starting the engine excessively charged with fuel by throttle blipping or other reasons: 1. Shift the transmission into neutral. 2. With the throttle fully opened, repeat kickstarter operation approximately 10 times very slowly to discharge excessive fuel from the engine. 3. Pull the hot start lever and kick-start the engine (Do not open the throttle.) 4. As soon as the engine starts, release the hot start lever. Stopping The Engine 1. Shift the transmission into neutral. 2. Turn the fuel valve OFF. 3. Lightly open the throttle 2 – 3 times, and then close it. 4. Depress and hold the engine stop button until the engine stops completely. NOTE: • Failure to close the fuel valve may cause the carburetor to overflow. (1) THROTTLE GRIP (2) ENGINE STOP BUTTON Break-In Procedure Help assure your CRF’s future reliability and performance by paying extra attention to how you ride during the first operating day or 15 miles (25 km). During this period, avoid full-throttle starts and rapid acceleration. This same procedure should be followed each time when: • Piston is replaced • Rings are replaced • Cylinder is replaced • Crankshaft or crank bearing are replaced

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. Beginning with the top screw, tighten the screws to 60-80 in-lbs (6.8-9.0 Nm)
