  If the KTM Motorcycle engine does not turn over when you press the starter button, there could be several reasons. It might be an operating error, so ensure you're following the correct start procedure. The battery could be discharged, so you should recharge it and check the charging voltage, open-circuit current, and the stator winding of the alternator. Also, the main fuse might be blown, requiring a replacement. A defective starter relay or starter motor could also be the cause, so you should check these components.

  If your KTM Motorcycle engine turns but doesn't start, several factors could be at play. Ensure the plug-in connection of the fuel hose is properly connected. A clogged fuel screen in the fuel hose connection could be the problem, so you should change the fuel screen. Check if the idle speed is correctly set and adjust it if necessary. If the spark plug is oily or wet, clean and dry it, or replace it if needed. Also, ensure the spark plug electrode gap is correctly adjusted to 0.8 mm (0.031 in). A frayed short circuit cable in the wiring harness or a defective kill switch can also prevent starting, so check the wiring harness and electrical system. Finally, a defect in the fuel injection system may be the reason; in this case, use the KTM diagnostics tool to read out the fault memory.

Why does my KTM Motorcycle have high oil consumption?

  Stephen MckeeAug 25, 2025
  If your KTM Motorcycle is consuming a high amount of oil, several factors could be responsible. A bent engine vent hose can cause increased oil consumption, so ensure the vent hose is routed without bends or replace it if necessary. An excessively high engine oil level can also lead to higher consumption, so check the engine oil level. Using engine oil that is too thin (low viscosity) can also contribute to the problem, so change the engine oil and oil filter, and clean the oil screens. Lastly, worn piston or cylinder can increase oil consumption, so measure the piston/cylinder mounting clearance.

  If your KTM Motorcycle engine overheats, several factors could be responsible. Check for coolant leakage and ensure the coolant level is correct. Insufficient air stream can also cause overheating, so switch off the engine when standing. Clean any dirt from the radiator fins. Foam formation in the cooling system might be the issue, requiring you to drain and refill the coolant. A bent radiator hose should be replaced.

Why does my KTM 450 XC-F 2018 engine have too little power?

  If your KTM Motorcycle engine has too little power, several issues could be the cause. A very dirty air filter can restrict performance, so clean the air filter and air filter box. A dirty fuel filter can also reduce power, so you should change it. A defect in the fuel injection system could be the problem, requiring you to use the KTM diagnostics tool to read out the fault memory. Check the exhaust system for leaks or deformation, and replace the glass fiber yarn filling in the main silencer if it's insufficient. Finally, insufficient valve clearance can also cause power loss, so adjust the valve clearance.
