  If your KTM Motorcycle engine has no idle, several things could be wrong. A blocked idling jet is a common cause, so you should check and set the carburetor components. Distorted adjusting screws on the carburetor can also prevent proper idling; in this case, adjust the idle speed. A defective spark plug can cause idling issues, so replace the spark plug. Finally, a defective ignition system can be the culprit, so check the ignition coil and the spark plug connector.

  If your KTM Motorcycle engine overheats, there are several potential causes. First, check the cooling system for leaks and ensure the coolant level is correct. Insufficient air stream can also cause overheating, so switch off the engine when standing. Dirty radiator fins can impede cooling, so clean the radiator fins. Foam formation in the cooling system can also lead to overheating; in this case, drain and refill the coolant. A damaged cylinder head or cylinder head gasket can cause overheating, so inspect these components. A bent radiator hose can restrict coolant flow, so replace the radiator hose if necessary. Finally, an incorrect ignition point due to a loose stator can cause overheating, so adjust the ignition.

  If your KTM Motorcycle engine stalls or pops into the carburetor, a lack of fuel could be the cause. Ensure the fuel tap is in the ON position and refuel if necessary. The engine taking in bad air can also lead to these issues, so check the intake flange and carburetor for tightness. A loose or oxidized connector or ignition coil can also cause these problems, so clean the connector and treat it with contact spray.

A carburetor running over because of a dirty or worn float needle can cause this problem, so check and set the carburetor components. Loose carburetor jets can also prevent the engine from speeding up, so check and set the carburetor components. A fault in the ignition system can also be the reason, so check the ignition system and adjust the ignition.
