I dont use it either. But my question is. Were you running it at 66:1 like they suggest you should for trail work? Or 40:1? I imagine that would make a big difference to spooge factor. The 800 is noticably thicker and has a higher flash point too. Never going to burn as clean unless if you're working the bike hard.
I use GRO/Amsoil Dominator, both at 50:1 and have always had an oily ring at the tip of the pipe. Stock jetting was the only time I ever had excessive smoke and spooge.
