  If your KTM Motorcycle engine turns but does not start, consider these potential causes: operating error, old fuel in the float chamber (if the motorcycle was out of use for a long time), a flooded engine, an oily or wet spark plug, an incorrect electrode distance on the spark plug, a defect in the ignition system, a short-circuit cable, oxidized plug connectors, or water in the carburetor. Go through the engine starting steps. Empty the carburetor float chamber if there is old fuel. Clean and dry the spark plug, adjusting or replacing it if needed. Adjust the plug gap to 0.7 mm (0.028 in). Check the wiring harness and electrical system for short circuits. Clean oxidized plug connectors with contact spray. Have the ignition system and carburetor components checked.

Why does my KTM 250 EXC-F EU 2010 Motorcycle engine have a lack of power?

  If your KTM Motorcycle engine has a lack of power, it could be due to an interrupted fuel feed, a severely contaminated air filter, a leaky or deformed exhaust system, too little glass fiber yarn filling in the main silencer, too little valve clearance, or a defective ignition system. Check the fuel tank breather and clean the fuel tap. Also, check and adjust the carburetor components. Clean the air filter. Inspect the exhaust system for damage and replace the glass fiber yarn filling if needed. Have the valve clearance adjusted and the ignition system checked.

  If the KTM Motorcycle engine does not speed up, potential causes include the carburetor running over due to a dirty or worn float needle, loose carburetor jets, or a defective ignition system. Have the carburetor components checked and adjusted. Also, have the ignition coil, CDI controller, spark plug connector, ignition pulse generator, and generator checked.
