Water pump! Happened to me with a brand new GTS300. Leaking water line causing the scoot to over heat and the fan would come on constantly.

Good luck.

Plus one for air leak around intake where the throttle body connects to the head. Look at the rubber connectors for previous " bodges" eg screwdriver witness marks or alternatively aging eg cracking of hoses. Lastly just check non of the hoses are loose on their connecting clips.
