i run in my yz400f today and all went well, i used to have a water issue but with water wetter and a new gasket its all good. after the ride when it was on the ute i found about 5 drops of white oil from the breather pipe. could this be from either combustion gasses or small amount of codensation when i put it together (it was pretty dam cold) and mixed with the oil. it is a sinthetic oil and i know i should have run it in with non -sinthetic. im about to change the after run in oil change but should i save my money for new gaskets. there was no water lost from radiator ?????? there is also a slight metalic ticking noise at idle that goes quieter when i put my hand on the header pipe (when not real hot) .
