Carburetor adjustment Basic information about the original carburetor setting The original carburetor setting was adapted for an altitude of approx. 500 meters (1600 ft.) above sea level, and the ambient temperature of approx. 20°C (68°F), mainly for off-road use and central European premium-grade fuel (ROZ 95). Mixing ratio 2-stroke motor oil : super fuel 1:40 . Basic information of changing the carburetor setting Always start out from the original carburetor setting. Essential requirements are a clean air filter system, air-tight exhaust system and an intact carburetor. Experience has shown that adjusting the main jet, the idling jet and the jet needle is sufficient and that changes of other parts of the carburetor will not greatly affect engine performance. RULE OF THUMB: high altitude or high temperatures  choose leaner carburetor adjustment low altitude or low temperatures  choose richer carburetor adjustment * WARNING * -ONLYUSE PREMIUM – GRADE GASOLINE ROZ 95 MIXED WITH HIGH – GRADE TWO – STROKE ENGINE OIL . OTHER TYPES OF GASOLINE CAN CAUSE ENGINE FAILURE , AND USE OF SAME WILL VOID YOUR WARRANTY . -ONLYUSE HIGH – GRADE 2- STROKE ENGINE OIL OF KNOWN BRANDS ( I . E .SHELL ADVANCE RACING X). -NOTENOUGH OIL OR LOW – GRADE OILCAN CAUSE EROSION OF THE PISTON . USING TOO MUCH OIL , THE ENGINE CAN START SMOKING AND FOUL THE SPARKPLUG . -INTHE CASE OFA LEANER ADJUSTMENT OF THE CARBURETOR PROCEED CAUTIOUSLY . ALWAYSREDUCETHEJETSIZEINSTEPSOFONENUMBERTOAVOID OVERHEATING AND PISTON SEIZURE . NOTE: If despite a changed adjustment the engine does not run properly, look for mechanical faults and check the ignition system. Basic information on carburetor wear As a result of engine vibrations, throttle valve, jet needle, and needle jet are subjected to increased wear. This wear may cause carburetor malfunction (e.g., overly rich mixture). Therefore, these parts should be replaced after 1000 hours of using. Idling range – A Operation with closed throttle valve. This range is influenced by the idle adjusting screw 1 . Only make adjustments when the engine is hot. The idling speed can be changed by turning the idle adjusting screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Opening up – B Engine behavior when the throttle opens. The idle jet and the shape of the throttle valve influences this range. If, despite good idling-speed and part-throttle setting, the engine sputters and smokes when the throttle is fully opened and develops its full power not smoothly but suddenly at high engine speeds, the mixture to the carburetor will be too rich, the fuel level too high or the float needle is leaking. Part-throttle range – C Operation with partly open throttle valve. This range is only influenced by the jet needle (shape and position). The optimum part-throttle setting is controlled by the idling setting in the lower range and by the main jet in the upper range. If the engine runs on a four-stroke cycle or with reduced power when it is accelerated with the throttle partly open, the jet needle must be lowered by one notch. If then the engine pings, especially when accelerating under full power at maximum engine revs, the jet needle should be raised. If these faults should occur at the lower end of the part throttle range at a four-stroke running, make the idling range leaner; if the engine pings, adjust the idling range richer

Starting & Stopping the Engine Always follow the proper starting procedure described below. Your CRF can be started with the transmission in gear by pulling in the clutch lever before operating the kickstarter or start button. Preparation Make sure that the transmission is in neutral. Turn the fuel valve ON. Fuel Valve Starting Procedure Always follow the proper starting procedure described as follow. 5. Warm up the engine; don’t operate the throttle. 6. About 15 seconds after the engine starts, push the choke knob back all the way to fully OFF. If idling is unstable, open the throttle slightly. Extended use of the choke may impair piston and cylinder wall lubrication and damage the engine. HighAirTemperature 35°C (95°F) or above 1. Turn the fuel valve (1) ON. 2. Do not use the choke. 3. Keep the throttle fully closed. 4. Start the engine following step 4 under “Normal Air Temperature.” LowAirTemperature 10°C (50°) or below 1. If the temperature is below 32°F (0°C), 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.) 2. Follow steps 1-5 under “Normal Air Temperature.” 3. Continue warming up the engine until it runs smoothly and responds to the throttle when the choke knob is pushed back all the way to fully OFF. Extended use of the choke may impair piston and cylinder wall lubrication and damage the engine. (cont’d) NOTICE NOTICE Basic Operating Instructions 15 (1) fuel valve The three-way fuel valve is used to control the flow of fuel from the fuel tank to the carburetor. ON -Turning the fuel valve ON before attempting to start the engine allows fuel to flow from the fuel tank to the carburetor. OFF -Turning the fuel valve OFF prevents the flow of fuel from the fuel tank to the carburetor. RES -Turning the fuel valve to RES allows fuel to flow from the reserve fuel supply to the carburetor. (1) fuel valve (2) choke knob Check the engine oil, transmission oil and coolant levels before starting the engine (pages 44,47,48). To restart a warm engine, follow the procedure for”High Air Temperature.” NormalAirTemperature 10°C-35°C (50°F-95°F) 1. Turn the fuel valve (1) ON. 2. Pull the choke knob (2) fully ON, if the engine is cold. 3. Keep the throttle fully closed. 4. Pull the clutch lever all the way in, and depress the start button. Or operate the kickstarter to start the engine. Starting from the top of the stroke, kick through to the bottom with a rapid, continuous motion. Do not operate the throttle. Allowing the kickstarter to snap back freely against the pedal stop can damage the engine

1) The “blue” colored screw in the image is the duration adjustment screw. Underneath the head of the screw is a lock nut and the bracket arm that the screw is threaded into. To decrease the amount of fuel squirted the adjustment screw is turned “clockwise” or in. To increase the amount of fuel squirted the adjustment screw is turned “counter clockwise” or out. To get the max, amount of decrease remove the screw and take the lock nut off of the screw. Then replace the screw into the cam arm, then replace the lock nut underneath the arm on the screw. this gives you another 3/32″ of an inch in which the screw can be screwed in.
2) Turn the adjustment screw fully clockwise or IN. Start your engine, Blip your throttle open, if the engine stutters, (hesitates), it is not getting enough fuel so turn the screw counter clockwise to increase the amount of fuel squirted from the accelerator pump into the carburetor. Keep blipping the throttle and adjusting the screw till the carburetor starts to cough. Stop here and turn the screw back in till the coughing stops. Tighten down the lock nut. This should give you the best throttle response with the least amount of coughing and backfiring out the carburetor. Timing Adjustment Screw This is the “Green” colored screw just above the Blue duration adjustment screw. The” Mucker” said it best,,,,, This upper screw adjusts the “timing” of the squirt. By altering it’s setting, you can advance or delay the onset of the fuel squirt. But probably, it won’t have to be touched

Intake Manifold: 1. Install MAP sensor in Mikuni manifold (Twin Cam only). 2. Attach the Mikuni manifold to the engine. Align the manifold before tightening the bolts. The flange surface of the Mikuni manifold should be parallel with the front of the engine’s cam cover. Use a level or angle meter to check this. Tighten the manifold bolts. 3. Attach the rubber flange to the Mikuni manifold with the furnished 5/16″x3/4″ bolts and washers. Choke Cables: Mikuni & Harley-Davidson Route the cable with largest radius bends possible. Check the cable for free-play after installation. If there is no free-play, the engine may run rich and deliver poor performance or low fuel mileage. Harley Cable (Twin Cam Kits: 42-19, 45-4) : 1. Remove the Harley choke cable from the stock carb. 2. Remove the spring and plunger from the cable. 3. Remove the spring and plunger from the Mikuni. 5. Install the Mikuni spring and plunger onto the Harley choke cable. Change nothing else; be sure to use the Harley plastic nut, not the Mikuni nut (See Figure 1). Total Kit Installation Instructions The HSR series carburetors are precise yet durable instruments; however, like any other piece of fine equipment, they require correct installation and reasonable care to assure optimum performance and long life. Extra time spent during installation will pay off in both short and long term performance and reliability. This Mikuni HSR carburetor kit is designed to be a bolt-on application, and as such, is set-up and jetted properly for most applications. However, since Harley-Davidson motors are often highly modified, alternate tuning settings may be required. The Mikuni Tuning Manual helps make jetting alterations and adjustments an easy matter. NOTE: Carburetor Kits not designated as C.A.R.B. exempt, are not legal for motor vehicles operated on public highways in the state of California, or in any other states and countries where similar laws apply. WARNING NOTE: NOTE: WARNING CAUTION NOTE: NOTE: TK-2 6. Install the new assembly into the Mikuni carburetor. Be careful to only gently tighten the plastic nut. 7. Loosen the knurled plastic friction nut behind the choke knob and check for free-play (see Figure 2). Figure 1: Harley nut with Mikuni spring & plunger Figure 2: Choke cable adjustments Mikuni Cable (Evo Kits: 42-8, 45-2 & 45-3) : 1. Remove nut, spring and plunger from the Mikuni. 2. Install the nut, spring and plunger onto the cable. 3. Install the assembly into the Mikuni HSR carburetor. Be careful to only gently tighten the plastic nut. 4. Check for free-play. Adjust the cable as necessary. An optional choke cable mounting bracket is included in the Evo kits for custom installations. Carburetor Installation: 1. Insert the carb fully into the rubber flange, align with engine and tighten the clamp. 2. Slip the fuel hose onto the carburetor’s fuel fitting and secure with the enclosed hose clamp. NOTE: Some Twin Cam installations may require removal of a small amount of fin material from the cylinders to clear the float bowl. Throttle Cables The HSR carburetor uses stock 1990 and later Harley- Davidson cables. However, if your Harley is fitted with some other carburetor, you may need to purchase a set of cables. See your dealer for the correct cable set. 1. Route the throttle cables with large radius curves and so they do not interfere with other components. 2. Screw the cable adjusters together to make them as short as possible. 3. Connect the “close” cable first (see Figure 3). 4. Install the “open” cable next (see Figure 3). 5. Adjust the opening cable until the slide can be opened fully. Snug the adjuster lock nut. 6. Turn the handlebar to the right and adjust the throttle free-play with the closing cable adjuster to approximately 1/8″ (see Figure 4)

THROTTLE CABLE ADJUSTMENT A) Rotate the throttle grip to the full open position, look into the throttle bore and see if the throttle valve (slide) opens completely. If the throttle valve does not open completely unscrew the adjuster on the opening cable until it does. This adjustment should be made carefully to assure maximum carburetor performance. After adjustment tighten the adjuster jam nut. B) After adjusting the open cable, adjust throttle freeplay with the closing (idle) cable to approximately 1/8″ an indicated in the following illustration. note It is very important to adjust the cables in the preceding described manner to ensure that the idle cable operates correctly for safety. It must close the throttle completely 2 PLEASE NOTE USE CAUTION PLEASE NOTE SAFETY WARNING pull open cable pull close cable SHOVELHEAD/IRONHEAD XL Installation Instructions Check and make sure that the throttle cables are routed properly by rechecking the throttle play as the handlebars are turned from side-to-side; the amount play should remain consistent. C) After the throttle cables have been adjusted, make sure that all the lock nuts are securely tightened. 5. AIR CLEANER A) The air filter bracket is attached to the crankcase with 1 long bolt, and a bracket-spacer. Removed the crankcase nut located between the tappet blocks & replace it with the enclosed bracket spacer; tighten the spacer securely. B) Remove the stud protectors from the K&N filter and place the two backing plates on the studs. Now slip the the filter onto the carburetor. C) Attach the 2 long brackets to the air filter studs with the enclosed nuts & flat washers, and to the bracket spacer with the enclosed bolt using the lock washers, and flat washers. When the carburetor and air cleaner are properly aligned, securely tighten all of the mounting hardware including the intake manifold clamps. In some cases it may be necessary to bend the brackets slightly to arrive at the correct fit. D) Use the enclosed hose clamps to secure the fuel hose to the petcock, and the HSR carburetor. The screw clamp goes on the petcock end and the spring clamp attaches to the carburetor end. E) Attach the chrome air filter cover with the enclosed socket head screw. 7. CHOKE CABLE INSTALLATION A) Attach the Mikuni choke cable bracket to the original choke cable bracket on the air cleaner stud with the enclose hardware as illustrated
