Looking for any help as to what this could be. I have a 13 650 xt with 51 hrs just back from the dealer for the 50hr service. When i start it, it blows smoke out of the exhaust. When i put my hand at the exhaust there is no oily discharge. The smoke is troublesome considering I just had it in for service. Any clue as to what is wrong?? The smoke isnt real thick, isnt blue in color, its just a white smoke, Also the 650 smells like burning oil….
