Apparently the guy was trying out some "new" oil that someone told him to use. The unfortunate part is that he didnt take into account that people would be riding behind him. I was the middle rider and sometimes would have to wait for the trailer, I could wait 4-5 minutes and still know what direction he went based on the lingering smoke. Next time I'll bring a respirator Just had to vent, it didnt ruin the day. That issue on top of having to go 45 minutes out of the way cause he didnt get up on time kind of made a bad first impression.
