No problems yet. It's just nasty. Leaves a yellow tint inside your intake. Most Pro Stock Mud Racers have been runnig it for a couple of years. Long before most knew about it.
It was easy to jet. Just go up 5 sizes on jets and down 1 or 2 air bleeds.
No way to cover up the smell. Trust me everyone will know you are running it. Or some dummys that don't know any better will accuse you of running alcohol.!! Trust me I still hear that one all the time.
