Why is my KTM Motorcycle engine overheating?

  If your KTM Motorcycle engine overheats, several factors could be responsible. It might be due to insufficient coolant, so you should check the cooling system for leaks and the coolant level. Insufficient airflow can also cause overheating, so switch off the engine when standing. Dirty radiator fins can be another cause, so ensure you clean them. Other potential issues include foam formation in the cooling system (in this case, drain and refill the coolant), a damaged cylinder head or cylinder head gasket (check these components), a bent radiator hose (replace it), or an incorrect ignition point due to a loose stator (adjust the ignition).

  If your KTM Motorcycle engine stalls or pops into the carburetor, it could be due to several reasons. One possibility is a lack of fuel; ensure the fuel tap is in the ON position and refuel if necessary. Another reason might be that the engine is taking in bad air; check the intake flange and carburetor for tightness. Also, a loose or oxidized connector or ignition coil could be the culprit; clean the connector and treat it with contact spray.
