Why does my KTM 300 EXC 2023 engine have too little power?
If your KTM Motorcycle engine has too little power, start by checking the air and fuel filters for dirt; clean or replace them as needed. Make sure the fuel screen is not dirty (replace it if needed) and that the fuel supply isn't interrupted by checking the fuel tank breather. Inspect the exhaust system for leaks or deformation and consider replacing the glass fiber yarn filling in the main silencer. Also, a faulty ignition could be the cause, so check the ignition coil, spark plug connector and the alternator’s stator winding. Finally, check the diaphragm and reed valve housing for damage and ensure that the ambient pressure is correctly stored.
