  If your KTM Motorcycle engine cranks but doesn’t start, there could be several reasons. It might be a blown fuse for the fuel pump, in which case you should replace fuse 4. Another possibility is that the connector is not attached to the fuel line, so connect the clutch to the fuel line. Also, the plug and socket connector on the wiring harness could be oxidized; remove the panel and fuel tank, clean the plug and socket connector, and spray with contact spray. If none of these solutions work, there may be an error in the injection system, and you should visit an authorized KTM workshop.

  Your KTM Motorcycle engine could be overheating due to several reasons. Check for insufficient cooling liquid and refill if necessary, also check the cooling system for leaks. Ensure the radiator fins are clean by washing the radiator with a water jet. Another potential cause is foam forming in the cooling system, which requires replacing the cooling liquid and using antifreeze with a brand name. Also, inspect the radiator hose for kinks or damage, correct the hose or replace it if needed. Finally, the thermostat could be defective and should be checked or replaced by an authorized KTM workshop.

Why does my KTM 690 LC4 Motorcycle have high oil consumption?
- K
  Kayla TuckerSep 7, 2025
  High oil consumption in your KTM Motorcycle could stem from a few issues. First, check the engine oil level when the engine is warm and correct if necessary, if it is too high. If the engine oil is too thin (viscosity), use thicker engine oil. Lastly, a kink in the engine vent hose could be the culprit, so remove the seat, move the tank back, and check engine vent hoses.
