    Why is my KTM 390 Duke 2016 using high oil consumption?
    • M
      martinporterAug 18, 2025
      High oil consumption in your KTM Motorcycle could stem from a few reasons. The engine vent hose might be bent, so ensure it's properly routed without bends, or replace it if needed. The engine oil level might be too high, so check it. Also, the engine oil might be too thin (low viscosity), suggesting that you should change the engine oil and oil filter, and clean the oil screens.

      If your KTM Motorcycle engine doesn't crank when you press the electric starter, several factors could be at play. It could be due to an operating error, so review the engine starting steps. The battery might be discharged, requiring a recharge. A blown fuse (1, 3, 4, or 8) could also be the culprit, in which case you should replace the affected fuse. Finally, check the ground connection to ensure it's properly connected.

      Connie PrinceAug 23, 2025
      If the ABS warning lamp illuminates on your KTM Motorcycle, the ABS fuse may be blown, requiring replacement. Another potential cause is a significant difference in wheel speeds between the front and rear wheels; in this case, stop the vehicle, switch off the ignition, and restart it. If these steps don't resolve the issue, there may be a malfunction in the ABS.

      If your KTM Motorcycle engine dies while you're riding, the first thing to check is the fuel level; you may need to refuel. Another possible cause is a blown fuse (1, 3, 4, or 8), which would require replacing the fuse.

    Why does my KTM 390 Duke 2016 Motorcycle engine have too little power?
    • S
      Scott GregoryAug 28, 2025
      There are several reasons why your KTM Motorcycle engine might have reduced power. A very dirty air filter could be restricting airflow, so you should replace it. A dirty fuel filter could also be the cause, so check the fuel pressure. Also, make sure there’s enough coolant in the cooling system and inspect it for leaks, and also check the coolant level. Radiator fins might be dirty, which requires cleaning. Foam formation in the cooling system can also cause this issue, requiring you to drain and then fill/bleed the cooling system. Finally, the thermostat could be defective, so check it.

      Katherine WilsonSep 5, 2025
      If your KTM Motorcycle engine only turns when the clutch lever is drawn, it's likely because the vehicle is in gear. Shift gear to neutral. The vehicle could also be in gear with the side stand folded out, so shift gear to neutral.
