Carbon monoxide If you must run your engine, ensure the place is well ventilated. Never run your engine in a closed area. Run your engine in an open area, if you have to run your engine in a closed area, be sure to use an extractor. Caution Exhaust contains toxic gas which may cause one to lose consciousness and even result in death. Gasoline Gasoline is a low ignition point and explosive material. Work in a well-ventilated place, no flame or spark should be allowed in the work place or where gasoline is being stored. Caution Gasoline is highly flammable, and may explode under some conditions, keep it away from children. Used engine oil Caution Prolonged contact with used engine oil (or transmission oil) may cause skin cancer although it might not be verified. We recommend that you wash your hands with soap and water right after contacting. Keep the used oil beyond reach of children. Hot components Caution Components of the engine and exhaust system can become extremely hot after engine running. They remain very hot even after the engine has been stopped for some time. When performing service work on these parts, wear insulated gloves and wait until cooling off. Battery Caution y Battery emits explosive gases; flame is strictly prohibited. Keep the place well ventilated when charging the battery. y Battery contains sulfuric acid (electrolyte) which can cause serious burns so be careful do not be spray on your eyes or skin. If you get battery acid on your skin, flush it off immediately with water. If you get battery acid in your eyes, flush it off immediately with water and then go to hospital to see an ophthalmologist. y If you swallow it by mistake, drink a lot of water or milk, and take some laxative such as castor oil or vegetable oil and then go to see a doctor. y Keep electrolyte beyond reach of children. Brake shoe Do not use an air hose or a dry brush to clean components of the brake system, use a vacuum cleaner or the equivalent to avoid dust flying. Caution Inhaling dust may cause disorders and cancer of the breathing system. Brake fluid Caution Spilling brake fluid on painted, plastic, or rubber parts may cause damage to the parts. Place a clean towel on the above-mentioned parts for protection when servicing the brake system. Keep the brake fluid beyond reach of children

Jets: These are made in various sizes ranging from.099 inches to.1875 inches, the larger sizes being used only for racing or very high performance engines. The two sizes most commonly found on production cars are the.090 inch and the.100 inch. The size of the jet will be found stamped on the jet head. The figure “nine”wilt indicate that it is the.090 inch and the figure “one”will indicate the.100 inch jet. When tuninga production car the jets size should be checked to make sure that it is of the size recommended by the manufacturers. Centering of Jet: If for any reason, the jet assembly has been removed, it will be ne cessary to recenter the jet. First, remove the clevis pin at the base of the jet which attaches the jet head to the jet operating lever. Withdraw the jet completely and remove the adjusting nut and spring, then replace the adjusting nut, without its spring, and screw it up toits highest position. Slide the Set into position until the jet head is against the base of the adjusting nut. When this has been done, find out if the piston is perfectly free by lifting it up with the finger and allowing it to drop. If the piston is not entirely free, slacken the jet screw and manipulate the lower part of the assembly, including the projecting part of the bottom half of the jet bearing, adjusting nut, and jet head. Make sure that this assembly is now slightly loose. The piston should then rise and fall quite freely as the needle is now able to move the jet into the required central position. The jet screw should now be tightened and a further check made to determine that the piston is still quite free. When complete freedom of the piston is achieved the jet adjusting nut should be removed, together with the jet, and the spring replaced. Experience has shown that a large percentage of carburetors, which have given trouble has been due to the incorrect centering of jets. Jet Needles— These are made in a great variety of sizes, probably now well over two hundred and fifty, and each type of engine hasaneedlethat has been selected, after very careful tests have been carried out, to give the best all-round performance. Most manufacturers actually give three alternative needles for each type and size of engine, these needles clearly being listed by the manufacturer “Standard”, “Rich”or”Weak”and before tuning is started the needle, which is marked on the shank should be checked against the manufacturer’srecommendation to make quite sure that the right needle is fitted; this is most important.

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.
