STEP 1 – BATTERY CONNECTION Locate the battery and disconnect the negative battery cable. Mount the module in the open area in front of the battery with 2-tie straps or velcro straps, directing the harness from the module towards the 6 o’clock position. STEP 2 – THROTTLE POSITION SENSOR (TPS): Remove the air cleaner assembly and unplug the TPS sensor connector at the TPS sensor. The harness includes (2) TPS connectors which should be routed under the gas tank into the factory wire loom to the TPS sensor. The TPS sensor is located on the left side of the throttle body. Plug the (2) TPS connectors from the module in between the TPS sensor and to the factory TPS connector. STEP 3 – O2 SENSOR: Systems equipped with factory O2 sensors Rear: Unplug the Rear O2 sensor connector from the factory harness, which is located at the Rear exhaust pipe. Route the module’s harness which includes (2) O2 sensor connectors and connect one connector to the Rear O2 sensor and connect the other connector to the main factory O2 sensor connector. Front: Unplug the Front O2 sensor connector from the factory harness, which is located at the Front exhaust pipe. Route the module’s harness which includes (2) O2 sensor connectors, and connect one connector to the Front O2 sensor and connect the other connector to the main factory O2 sensor connector. Systems not equipped with factory O2 sensors NOTE: Many aftermarket exhaust systems are now equipped with plugged O2 sensor bungs which can be removed to accept an aftermarket O2 sensor. Typically these bungs already have a thread size of 18 mm x 1.5 mm. Exhaust systems not equipped with O2 sensor bungs need to have the supplied 18 mm x 1.5 mm thread size bung welded to the exhaust pipe in order to install an O2 sensor. The O2 sensor bung should be installed 3 to 6 inches away from the rear cylinder exhaust port and in front of the exhaust torque tube pipe area. The module prefers to receive information from the O2 sensor from an area that is NOT contaminated from atmospheric air. This air may enter through the tail pipe of an unrestricted or un-baffled exhaust pipe. The bung should not be installed in the “5 to 7 o’clock” area. If mounted in this area the O2 sensor can be damaged. The moisture from the gases exiting from the rear cylinder exhaust port will harm the ceramic shell element of the O2 sensor.

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

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). Mixing ratio 2-stroke motor oil : super fuel 1:40 – 1:60. Basic information on a change of 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.

1. Turn off the ignition switch before proceeding. 2. Select a convenient mounting location for the Bosch sensor. In general, the sensor should be mounted as close to the exhaust valve or exhaust manifold as practical. When choosing a mounting location, allow several inches clearance for the sensor wire harness. The wire harness must exit straight out from the sensor. Do not loop the harness back onto the sensor body. The sensor responds to oxygen pressure. Excessive backpressure will cause a reading error. For turbocharged applications, you must mount the sensor downstream of the turbo. 3. For temporary use during dyno tuning, you can mount the Bosch wide-band sensor in place of one of the original equipment rear oxygen sensors (after the catalytic converter). You can also use a sniffer in the tailpipe. For permanent mounting, an 18 x 1.5 mm weld nut must be welded onto the exhaust pipe. After welding, run an 18 x 1.5 mm tap through the threads. Failure to clean the threads may result in sensor damage. Note that most automotive muffler shops are familiar with oxygen sensor weld nut installation on custom pipes. Do not install the sensor until after the free air calibration procedure described in the following section. Always use an anti-seize lubricant such as Permatex 133A on the sensor threads. 4. Install the WEGO II unit. The WEGO II unit should be mounted where the LCD display will be visible during testing. You can secure the WEGO II unit with Velcro tape strips. 5. Connect the Bosch sensor to the 6 pin mating connector on the WEGO II wire harness. 6. Refer to Figure 1. Connect the black WEGO II wire to frame ground using the supplied ring terminal. Try to use an existing wire harness ground location. Do not extend the WEGO II ground wire or ground the WEGO II to the battery minus terminal or to the engine. 7. Connect the red WEGO II wire to switched +12 volt power. You can usually find switched +12V power at an accessory fuse on the fuse block. You can use the supplied fuse tap and 3/16″ female crimp terminal for this purpose

Am I too small for this motorcycle? Duke – Sun May 14 17:38:31 2000 I’m only about 5’2″ and don’t have a problem, even though I can only touch the ground with the ends of my toes. Once you get a feel for the balance of the bike it’s not hard to keep everything upright. Only place I have trouble is pushing the bike backwards in a parking lot. Usually I just walk the bike (beside it) to where I can get on and get going. How does the EX500 compare to the EX250? Craig M. – Mon May 22 10:23:29 2000 I have both the EX250 and the EX500; both are Y2K models. The 250 is a screamer that performs well and can easily get me into trouble. My only complaints about the 250 are the excessive nose dive when getting on the front brake hard and the skittishness of the rear during high speed cornering. Both are easily corrected with suspension adjustments, I’ve just been too lazy to get the parts and do the work. A bit more wind protection would be great too. The 500 addresses these problems, the diving of the front end (to a degree); the rear’s skittishness and the wind protection. A plus for the 500 is the greater torque and power off the line; it pulls stronger (in my opinion) and will get you into illegal speed territory just a bit quicker than the 250. With greater weight, is has more stability in high speed and windy situations. Insurance is just about the same for both, with the 250 getting the nod for gas mileage. Service requirements are almost identical for both as well, being that they’re both parallel twins, the technology is the virtually the same. The downfalls of the 500: $2K more than the 250 (can do a lot to the 250 with that kind of money); buzzy mirrors, barely useful; heavier weight to have to push around the garage; lesser gas mileage (55-60 MPG; 250 pushes 70 MPG easily); engine is worse than a nervous dog shaking around at idle and at speed (here the 250 is far superior and much smoother). In my opinion, the 500 is a better suited for a larger rider, from a comfort standpoint. I feel I can stretch out a bit more on it than the 250 (I’m 5′ 9″, 160 lbs). The 250′s brakes are better tuned than the 500 and the shifter is much smoother. That may be due to the 3,500 mile difference between the two bikes. Bottom line, both bikes are great, the 250 is now my wife’s ride (mainly) and the 500′s mine (unless she steals the keys away). In time, I’ll make the adjustments to the 250; she doesn’t push it like I do.
