I dont know if anyone here has heard of or used Seafoam but i can contest that this stuff is awesome. I got turned on to it from the guys over at the delphi forum (Gadget). Guys/Gals this stuff works great in our nomads. I use it in my wifes bike (Kawa 06 900LT) and in my riding lawn mower and it really seems to do what it says. I use it twice maybe three times a year in my bikes and it really seems to make the rides run better and smoother. I would and have recommended this stuff to anyone. Works great in my steps sons cars too. It can be bought at like Car quest, Napa, etc. Here is a link to more info below.
