What to do if my KTM 990 Super Duke 2008 Motorcycle engine cranks but doesn’t start?

If your KTM Motorcycle engine cranks but doesn’t start, there could be several reasons. First, ensure you are following the correct starting procedure as outlined in the driving instructions. Check fuse 4, as a blown fuse for the fuel pump could be the issue, and replace it if necessary. Also, verify that the clutch is properly connected to the fuel line. Inspect the plug and socket connector on the wiring harness for oxidation; if found, remove the panel and fuel tank, clean the connector, and apply contact spray. If these steps don't resolve the issue, there may be an error in the injection system, and it's best to visit an authorized KTM workshop.

If your KTM Motorcycle engine won't reach full power, it could be due to a heavily soiled air or fuel filter. In this case, have the air filter or fuel filter replaced at an authorized KTM workshop. Another possible cause is an error in the injection system, which also requires a visit to an authorized KTM workshop.

Why does my KTM Motorcycle engine overheat?

T
Tina PetersonAug 9, 2025
Your KTM Motorcycle engine may overheat due to several reasons. Check if the cooling liquid level is sufficient and refill if necessary, also inspect the cooling system for any leaks. Ensure the radiator fins are clean; if they're dirty, clean them with a water jet. Foam in the cooling system can also cause overheating, so replace the cooling liquid with a brand-name antifreeze. Inspect the radiator hose for kinks or damage; correct the hose's routing or replace it if damaged. Finally, a defective thermostat could be the cause, so have it checked or replaced by an authorized KTM workshop.
