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 .

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

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

Repair manual KTM 250 / 300 / 380 Art No 3206004 -E 2-2C main jet jet needle jet needle air control screw idle adjusting screw idle jet throttle valve Idling range A Operation with closed throttle valve. This range is influenced by the position of the air control screw 1 and the idle adjusting screw 2 . Only make adjustments when the engine is hot. To this end, slightly increase the idling speed of the engine by means of the idle adjusting screw. Turning it clockwise produces a higher idling speed and turning the screw counterclockwise produces a lower idling speed. Create a round and stable engine speed using the air control screw (basic position of the air control screw = open by 1.5 turns). Then adjust to the normal idling speed by means of the idle adjusting screw. 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. Full throttle range D Operation with the throttle fully open (flat out). This range is influenced by the main jet and the jet needle. If the porcelain of the new spark plug is found to have a very bright or white coating or if the engine rings, after a short distance of riding flat out, a larger main jet is required. If the porcelain is dark brown or black with soot the main jet must be replaced by a smaller one. mixture too rich: too much fuel in proportion to air mixture too lean: not enough fuel in proportion to air 1 2 OPERATING RANGES OF THE CARBURETOR 2-3C Carburetor adjustment Basic information on 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 MOZ).

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.

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

1. Protect the rear portion of the front fender with a towel or other thick, soft cloth. 2. Remove the OEM engine guards if they have been installed on the motorcycle. Or, if OEM engine guards are not present, Remove the two lower engine mount bolts. These bolts are located on the inside of the right and left frame rails, and will be replaced with the longer 10mm bolts included with your new engine guard. 3. Position the engine guard so that the lower brackets point towards the rear of the motorcycle, and slide the engine guard into the space between the front wheel and the frame. 4. Raise the guard until the upper V” mount is located between the frame rails. Note: Your new Barons engine guard is equipped with a unique upper V” mount clamp. This clamp becomes a cradle for the upper frame supports when it is inserted between the frame rails. 5. Rotate the engine guard until the lower mounting brackets are aligned with the lower engine mount holes. Due to production line tolerances in both the motorcycle and the engine guard, the mounting brackets may be too wide or too narrow for the frame. If this is the case, remove the guard from the motorcycle. Place the guard on a flat, firm surface. Insert a towel or other protective material between the guard and the surface. Using a rubber mallet or a block of wood and a hammer, tap the lower brackets until they are correctly spaced. 6. Insert the new 10mm bolts and washers, and finger tighten only. 7. Tighten each 3/8″ bolt in the upper clamp evenly by using a 9/16″ socket or a wrench. Snug down each bolt until it draws the front of the upper clamp into contact with the upper frame supports, then adjust these bolts accordingly to achieve equal spacing between each floorboard and the lower engine guard rail. 8. Tighten the jam nuts against the washers to lock each bolt in place. CAUTION! It is critical that you do not over-tighten these bolts. Tighten all remaining nuts and bolts securely. If necessary, slightly loosen rear brake line banjo bolt and rotate banjo fitting for clearance with engine guard. Tighten banjo bolt and check brake for proper operation. You must re-tighten all four of the engine guard mounting bolts after 100 miles of riding! Care & Cleaning: Engine guards take the full brunt of the worst of what the weather in your area has to offer, making it critical that proper and complete cleaning take place on a weekly basis, or corrosion will occur which is not covered by warranty! Proper cleaning procedure would be to use a product like Simple Green, LOC, Salt-Away or similar. Mix a strong batch and apply it liberally with a soft towel or soft nylon brush to the entire

1. Make sure the ignition timing is correct 2. Adjust the valves as necessary to ensure proper operation 3. Run the engine to warm it up a bit 4. Adjust the float setting. To do this, remove the carburetors (leave the throttle cables attached), remove the bowl and turn the carburetor upside down (fuel will spill). The float should look like this: Adjust as necessary by bending the float support (#37 in Figure 1). Reinstall Installation and idle adjustment 1. First you must adjust the idle. It is acceptable per the manual to adjust the idle by using the idle adjust screws (11). This usually involves screwing them then backing out 1 to 1.5 turns. Or you can adjust looking at the sliders 2. If installing the carburetors: a. Remove the cover (2) b. Reomve the slider (3) c. Place the throttle cable through the guide (18) with the spring (4) on the cable. d. Route the cable through the slide catch (6) e. Insert the slide assembly into the chamber and make sure it easily slides up and down. Direct the needle (8) into the opening of the diffuser (angled side visible). f. Screw assembly together and verify via throttle movement that slide moves freely. Attach fuel delivery lines to (12). 3. Using the idle set screw (11) raise the slider so the lower edge is 1-2 mm. 4. Assemble to engine using the proper gaskets (paper – felt – paper). 5. Using the locknut (26) adjust the free play of the throttle cable (2-3 mm) 6. Adjust the idle mixture screw – turn in completely then out 1 to 1.5 turns. * Starting using the K68′s (cold weather) 1. Verify fuel flow. Apply choke (pull 52 in Fig1). 2. Using the ticklers (13) allow fuel to enter the bowl until fuel drains from (14) 3. With the ignition off, kick 1 or 2 times 4. Turn ignition on, and as soon as engine is warmed up (maybe sooner) push choke mechanisms to open choke Idle Adjustment (engine running and warm) 1. Remove one of the spark plug caps, and with the cap shorted, adjust (11) to decrease RPM’s to a point of being minimally steady. 2. Adjust the mixture (15) out until RPM’s decrease. Turn in until RPM’s increase slightly. Then turn in screws ¼ to 1/3 revoultion. 3. Do the same for the second carburetor with the first spark plug cap shorted. 4. With both cylinders, adjust each idle (11) on each carburetor the same amount each until it’s at a steady, minimal RPM. Use small changes. (at this point you can use your airflow tool to check). 5. Sharply increase, then decrease throttle. Then engine must return to low RPMs smoothly. If the engine goes below limits, readjust (11) from step 4. Synchronization of the K68 Note: Rather than using the opposite cylinder shorted to test the pull of the live cylinder carburetor, you can use something like a Twinmax connected to the test ports (27 Fig 1). Or, if you have a model without these ports, use a Synchrometer (Appendix 2) held against the face of the carburetor. These tools merely show airflow passing through each carburetor (which is dependent on the position and wear on the slide). If using these tools, it’s not necessary to do the following steps. You wil want to use a throttle guide (Appendix 1), to show airflow at various throttle settings. Using the flow meter of your choice make sure each carburetor is the same at the various throttle settings. 1. Place the motorcycle on the center stand ensuring the rear wheel is suspended 2. Make sure you have large area to work with (safety issues here) 3. Shift into the highest gear with the engine running 4. Short one spark plug cap to the cylinder (using a nail or something in the fins) 5. Increase the speed to 40-50 km/hr 6. Fix the throttle using the throttle (maybe using a throttle stop screw under the throttle housing). 7. Reconnect other cylinder and using the opposite carburetor determine the speed which should be the same as the first. 8. Adjust the position of this slide to achieve the referenced speed using the locknut at the top of the carburetor.
