Ducati st4s overheat My 2002 ST4S gets over heat to 120 degree Celsius and engine cut off whenever in slow traffic with outdoor temperature around 25-28 degree Celsius. Anyway to solve? Or any easy modification to improve? Engine oil, coolant are newly changed.

Need a faster answer?
Hi, Bikermok and the usual suspects are:
1. Insufficient oil supply, or oil not circulating.
2. Insufficient air flows over the engine.
3. Heavy carbon deposits.
4. Ignition timing retarded due to faulty MAP, CKP, and/or CMP sensors.
5. Leaking intake or exhaust valve.
6. Water coolant low or pump failure.
