How to troubleshoot a KTM Motorcycle engine that won't switch on?
If your KTM Motorcycle engine doesn't switch on, first ensure there's no operating error by switching on the ignition and setting the transmission to neutral. If that's not the issue, the battery might be dead; in this case, charge the battery and determine why it discharged. Alternatively, the ignition lock or emergency off tip switch could be defective, requiring a check.
What to do if my KTM 400 LS-E/MIL Motorcycle engine switches on but does not start?
If your KTM Motorcycle engine switches on but doesn't start, first ensure there is no operating error. Open the fuel tap, refuel if necessary, avoid using the choke, and carefully follow the starting instructions. If the motorcycle hasn't been used for a while, the old fuel in the float chamber might be the issue. Drain the old fuel. Also, check for an interrupted fuel supply by disconnecting the fuel hose from the carburetor and opening the fuel tap. If no fuel runs out, inspect the tank ventilation or clean the fuel tap. If the engine is drowned, fully open the throttle when starting or replace the spark plug. Clean and dry or replace a sooted or wet spark plug. Set the electrode distance to 0.9 mm if it's too large. If there is no spark, replace the spark plug connector.
