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.

The R&D high performance Air Filter Kit will improve acceleration and top speed performance by increasing air flow and reducing air temperatures that enter directly into the Ultra 250X’s air plenum box area. The O.E.M. air plenum box on the Ultra 250X is a great design that will flow plenty of air. However, the air that feeds the plenum box is heated by the engine. R&D has created an easy to install “flat filter” that installs directly in place of the large center access inspection cover located directly under the main glove box. The R&D Flat Air Filter insert will allow unrestricted fresh and cool air to enter the air plenum box area which will add power you can feel and a nice high performance tone. The R&D Performance Filter Kit also features two filters, one for each of the surge and blowoff protections valves. The O.E.M. surge valve recycles compressed hot air back into the air box plenum at idle and under deceleration conditions. The R&D surge and blowoff valve filter kit removes the air recycling hoses which will keep the hot air from entering the air plenum box reducing the engines intake air temperatures. The R&D Ultra 250X Air Filter Kit offers great performance tips on how to remove the restrictive air vent hoses which will further reduce the under seat ambient air temperatures. The R&D Filter system does not remove or alter the O.E.M. plenum box in any way, therefore there are no questions to be answered regarding water ingestion

This manual is intended as a guide for users of Mikuni carburetors who want to learn the adjusting method to the best performance from our products. In motorcycles, special tuning of the engine is now considereda routine practice. The arrows that appear in the drawings in this text show the direction in which air, fuel and an air-fuel mixture flows, respectively. ¢JAir Fuel “Mixture Mounting angle fore and aft inclination of the carb should not exceed approx Function of a carburetor The function of a carburetor is to produce combustible air-fuel mixture, by breaking fuel into tiny particles (in the form of vapor) and by mixing the fuel with air in a proper ratio, and to deliver the mixture to the engine. A proper ratio (mixture ratio or air-fuel ratio) means an ideal air-fuel mixture that can burn without leaving an excess of fuel or air, Whether the proper mixture ratio is maintained or not holds the key to the efficient engine operation, 2. Air-fuel mixture required by the engine (Fig. 1) The ratio of a mixture of fuel and air is called the mixture ratio or the air-fuel ratio and is generally expressed by the weight proportion. Theoretically, the amount of air required for complete combustion of 1 gram of fuel under normal conditions is

1. Remove both seats and the plastic seat pans under the seats. 2. Remove the engine cover 3. Remove the air-box by removing the cross-bar support that runs under the air-box to the framing on each side by the seat framing and disconnect the air box from the carburetor and from the plastic intake in the rear. 4. Disconnect the engine breather hose from the bottom of the air box 5. Set the air-box to the side 6. Disconnect the plug going to the stock carburetor, this is the electronic choke. Wrap the end left on the vehicle with electrical tape. 7. Cut the fuel line just above the fitting on the passenger side of the carb 8. Remove the side cover off the drivers side of the carb where the throttle cable goes in, see fig. #1 9. Pull the throttle cable out and then remove the throttle cable end from the throttle plate See Fig. #2 10. Loosen the clamp on the rear of the carb holding the carb on 11. Pull the carb out of the intake boot 12. Set OE carb to the side. 13. Push the new Carb into the intake boot making sure the carb is perfectly vertical and then tighten the clamp back up. The new carb is slightly larger than the stock one so some additional pressure will be needed to get it in. 14. Route all the breather lines connected to the carb down under the carb. 15. Connect the throttle cable onto the new carb but putting the cable end in the bottom hole of the throttle plate on the passenger side of the carb allowing the cable to ride in the slot in the plate and then turn the throttle plate clock wise allowing the threaded end of the cable to fit into the lower round hole of the throttle cable connection plate. See Fig. #3 16. Make sure you have a nut on each side of the plate turn the nut on the outside of the plate to take up the slack in the throttle cable then tighten the nut on the inside of the plate. See Fig. #3 17. Push the fuel line onto the fuel inlet on the passenger side of the carb and install the supplied clamp to hold it on. The fuel line will be a little hard to push on. 18. DO NOT ATTEMPT TO INSTALL THE CHOKE CABLE PARTS SUPPLIED IN THE KIT UNTIL AFTER THE CHOKE CABLE ITSELF IS INSTALLED AND READY TO SCREW INTO THE CARBUETOR. 19. To install the supplied choke cable, drill a 3/8″ hole in the dash on the left side of the steering wheel in a location convenient to your left hand. 20. Remove the plastic nut from the bottom of the choke handle on the choke cable. 21. Push the choke cable thru the hole you drilled and then slide the nut over the cable to the inside of the dash and reinstall back on the back of the choke mechanism.

Air HoseInstallation. Choose the most convenient loca- tiononyour motorcycle for the air fill valve. Drilla 5/16″hole and install the air fill valve as shown in Figure 3orsecure air fill valve to frame tube. 2. Keep hose ends clean during installation because dirt can cause air leaks. 3. Install hose connector, tube clamp and two O-rings onto one end of the air hose (See Figures4&5) Apply rubber lubricant (soap solution, not oil) to the O-rings to ease installation on the air hose& into the shock absorber inlet. Plastic connector should just bottom on fitting. Do not overtighten! The function of the nut is to hold everything together in place, the O- rings do the sealing. Fin- gertightenonly (10 in/lb maximum). 4. After routing the air hose, trim the length to fit air fill valve. Install hose connector, tube clamp, and twoO-rings onto end of hose (See figures 4&5). Lubricate as above and assemble to air fill valve. Use the same procedure formating hose. Important —leaveasmall amount of slack in hose near shock absorber to allow for the slight move- mentofthe shock. Caution! Do not install hose near ex- haustsystem, battery or any other sharp edges or seat movement. Keep hoses clear of moving parts such as wheels or suspension components. Do not allow hoses to have excess slack and sag below the motorcycle. The hoses could catch on road surfaces or debris and could be damaged while the motorcycle is in motion. 5. If necessary the air hose can be secured along the motorcycle’swiringharness with tie-wraps. 6. Testing: Inflate system to 50 psi. Apply soapy water solution to all connections and check for air leaks. If there are any leaks, disconnect the suspected fitting and check for dirt or damage to the air line or the O-rings. Remove any dirt or foreign matter, re-lubricate the O-rings and reinstall. If unable to locate the leak, remove rubber boot from shocks and submerge pressurized components under water (in- cludingT-Valve) and check for leaks. If you cannot solve the air leak problem, please contact our technical staff for assistance

Basic Tuning Adjustments 1. The following instructions are for basic fuel tuning. Modes 1,2, & 3 are allowing adjustments to increase and decrease the amount of fuel the engine needs. Modes 4 & 5 are for advanced tuning only. DO NOT change modes 4 & 5 when doing basic tuning! 2. To help understand how these modes work, you can think of them as if you were working with a carburetor. 3. Remember each time you push the MODE button you will be advancing to the next mode. Push the MODE button once and you are now in mode 1, push the MODE button again and you are now in mode 2 and so on. You only need to be concerned with modes 1, 2 & 3 for basic tuning. Modes 4 & 5 are for advanced tuning ONLY. 4. If you need to go back to the settings that were pre programmed when you purchased the controller, just look at the picture in each mode, the colored square represents where the settings were when you purchased the controller. 5. Looking at the controller you will see eight lights with numbers under them, this is what you need to look at when changing settings. The #1 light on the controller represents the leanest setting. TRINITY RACING DOES NOT TAKE REPONSIBLITY FOR DAMAGES THAT MAY OCCUR DURING OPERATION OF YOUR VEHICLE UNDER IMPROPER JET SETTINGS. IT IS THE FINAL RESPONSIBLITY OF THE OWNER/RIDER TO ADJUST JETTING TO SPECIFIC RIDING CONDITIONS AND ELEVATION BEFORE RIDING. WARNING! 1.877.FAS TOYS 2.Remove both seats 6. Re-install engine cover and seats. 6. Mode 1 green light represents idle & cruise adjustment (i.e. pilot jet). To adjust this setting push the MODE button once and then push the plus or minus buttons to adjust fuel as needed. 7. Mode 2 yellow light represents an additional amount of fuel added during acceleration (i.e. needle position). To adjust this setting, push MODE twice and then push the plus or minus buttons to adjust fuel as needed. 12 34 56 7 8 12 34 56 7 8 8. Mode 3 red light represents more fuel being added during full throttle (i.e. main jet). To adjust this setting push the MODE button three times and then push the plus or minus buttons to adjust fuel as needed. 9. If you are confident about your tuning skills and feel you need to adjust other parameters, see Advanced Tuning. 12 34 56 7 8 Advanced Tuning Adjustments 1. Advance tuning has two modes in which to adjust. They are called mode 4 and mode 5. In basic tuning, you are changing the amount of fuel that the engine receives, but with advance tuning, you will be changing when the fuel will be available. In each mode you can adjust how soon the fuel delivery occurs. 2. Mode 4 yellow light and blue light represent when the fuel delivery is available during partial throttle acceleration. To adjust this setting, push the MODE button four times and then push the plus or minus buttons to adjust fuel as needed. Only the yellow light will be changing.
