Engine number, engine type The engine number and engine type are stamped on the right hand side of the engine below the chain sprocket.
Choke lever (EGS) If the choke lever is pulled backwards, a bore will be opened in the carburetor through which the engine may draw in additional fuel. This produces a „rich“ fuel/air mixture necessary for cold start. If the choke lever is pushed forward up to the stop, the bore will be closed again.

Hot-start device The carburetor is equipped with a hot-start device which makes it easier to start the engine when hot. Press the hot-start button until it engages. This will slightly lift the throttle valve. Once the engine is running, pull the hot-start button back into its original position.
Compression damping of fork The compression damping mechanism is built into the left fork tube. It only regu- lates the degree of damping during compression. By using the knob (COM), the degree of damping of the compression can be adjusted. Turn the knob clockwise to increase damping, turn it counterclockwise to reduce damping during compression.
Arrange for the as close as possible to the middle of the vehicle; distribute the braking system to be checked by a KTM specialist, as complete weight evenly between the front and rear wheel. Never exceed failure of the braking system can be avoided.

In this case, consult an authorized KTM dealer immediately. BRAKE FLUID: KTM fills the brake systems with CASTROL DOT 5.1 brake fluid, one of the best brake fluids that is currently available. We recommend that you continue to use it.
Checking of brake fluid level - front brake The brake fluid reservoir is linked with the hand brake cylinder at the handlebar and the reservoir is provided with an inspection glass. With the reservoir in a hori- zontal position, the brake fluid level should not drop below the middle of the glass. The reservoir should be kept completely full at all times for best performance.

CARBURETOR – Adjust idling (DellOrto)* Idling adjustment of the carburetor strongly affects the engine’s starting behavior. That is, an engine whose idling speed is adjusted correctly will be easier to start than one whose idling speed has not been adjusted correctly. Idling is controlled by the throttle stop screw and the mixture control screw .
Adjusting the throttle cable (SX, SC)* There must always be 3-5 mm play in the throttle cable. To check this, move back the protective cover on the twist grip. It must be possible to lift the outer 3-5 mm covering of the cable 3-5 mm (0,12-0,20 in) from the counterbearing of the twist grip, until resistance is felt.
Adjusting the choke cable (EGS)* At the choke cable, there must always exist a play of approx. 2 mm. To check this, push choke lever fully forward and pull protective cover from the adjuster piece . Now, it must be possible to lift the outer covering of the cable by approx.
Checking engine oil level Allow the engine to run at idle for about 4 minutes. Turn off the engine and place the motorcycle on a flat, level surface (main stand). Take out the oil dipstick and wipe it off with a cloth. SCREW THE OIL DIPSTICK COMPLETELY INTO THE FILLER HOLE AND THEN The oil level should be within the flat area of the oil dipstick.
Changing the engine oil (SX, SC)* The engine oil change is to be carried out when the engine is still warm. WARNING N ENGINE HAVING BEEN RUN WARM AND THE ENGINE OIL IN IT ARE VERY HOT DO NOT BURN YOURSELF Place the motorbike on a horizontal surface.
Oil change and bleeding of the oil system (EGS)* NOTE: For improved cooling of the engine oil the front pipe of the frame is inter- grated into the oil circuit. When changing the oil, the engine oil has also to be drained from the front pipe.
Changing oil filter * Replace the oil filter when changing the engine oil. Press the foot brake lever and place a screwdriver or similar between foot brake lever and stopper roll so that the oil filter cover is more accessible. Remove banjo bolt and the three allen head screws.
We would like to point out that many operations cannot be performed by oneself. In case of uncertainty, please contact a KTM-dealer.
