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

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)

Step 1: Identify the key components that complete our Superbike kit: You should have 2 lines (front kit), 1 double banjo bolt and 2 lower adapters. There are also a total of 7 washers. 5 will be used, and 2 are spares. We strongly suggest having a professional mechanic install these brake lines; all other installations VOID warranty. Inspect your brake system after every race. Step 2: To ensure no paint damage from a brake fluid spill, completely cover the front end of the bike. This process is messy, and brake fluid WILL drip! Step 3: Uninstall stock hoses; be aware of how the stock system was routed in case you need to re-install it. Step 4: Install the Galfer adapters onto the right and left calipers. Thread each adapter into the calipers with one washer, and torque at 12 to 13 ft pounds. (See picture S4) Step 5: Install the right and left lines to the calipers, using the shorter line on the right side. These lines will travel from the master cylinder to the calipers; a double banjo bolt (see picture S5) is included to run two lines down. The positioning sequence on the master cylinder is as follows: Master cylinder, washer, straight banjo (from right line), washer, 12-degree banjo (from left line), washer, and double banjo hex. Double banjo bolt torque level is 12 FT Pounds. ( See picture S6) Make sure that the 90-degree fittings on each caliper are pointing away from the bike just a little bit (see pictures S7 through S9 of calipers) . Thread each banjo end into the adapter, and torque to 6 ½ Ft pounds. Before you proceed to the next step, please check for clearance of the lines. Compress the front end to make sure that the lines are not binding with anything. When the front end is fully extended or fully compressed, double check that the lines are traveling correctly and clear from any obstructions. Once the lines have been checked for clearance, we recommend using a zip-tie to bring the lines together about an inch above the lower triple clamp area. (Picture S10) Step 6: Bleed brake system according to owner’s manual, and build appropriate pressure. Finishing with DOT 4-brake fluid is recommended.
