Why does my KTM 250 XC TPI Motorcycle engine have too little power?
- K
  Kevin BryanJul 28, 2025
  If your KTM Motorcycle engine lacks power, it might be due to several reasons. There could be an error in the electronic fuel injection, which requires reading the fault memory using the Husqvarna Motorcycles diagnostics tool. Another cause might be an interrupted fuel supply, so check the fuel tank breather. Also, inspect the exhaust system for leaks or deformation and consider changing the glass fiber yarn filling of the main silencer. Other potential issues include a defective ignition system (check the ignition coil and spark plug connector), a damaged diaphragm or reed valve housing, or incorrectly stored ambient pressure, which needs to be reprogrammed.

  If your KTM Motorcycle engine dies during a trip, it could be due to a lack of fuel, so refuel your motorcycle. Another potential cause is the engine taking in false air; ensure the intake flange is firmly seated. Also, check for a loose or oxidized connector or ignition coil, and if found, clean the connector and treat it with contact spray. Finally, an incorrectly stored ambient pressure can also cause this issue, so you may need to program the ambient pressure.

How to fix KTM 250 XC TPI Motorcycle engine overheating?
- M
  Mrs. Elizabeth GarciaAug 6, 2025
  If your KTM Motorcycle engine overheats, several factors could be the cause. First, check the cooling system for leakage and verify the coolant level, as too little coolant can lead to overheating. Insufficient air stream can also cause this, so switch off the engine when stationary. Dirty radiator fins can impede cooling, so clean them. Foam formation in the cooling system is another possibility, requiring you to drain and refill the coolant. Additionally, inspect the cylinder head and cylinder head gasket for damage. A bent radiator hose should be replaced, and a defective thermostat should be checked, with a guideline opening temperature of 70 °C (158 °F).

  Dennis HarrisAug 11, 2025
  If you notice white smoke emission (steam in exhaust gas) from your KTM Motorcycle, it may indicate a damaged cylinder head or cylinder head gasket. You should check these components for damage.

Why is gear oil coming out of the vent hose on my KTM Motorcycle?
- M
  Matthew RobinsonAug 16, 2025
  If gear oil is exiting at the vent hose of your KTM Motorcycle, it is likely that too much gear oil was added. Check the gear oil level to resolve this issue.
