amazing stuff works great
the part someone said about just drive with the chain a couple hundred miles then lube it or whatever the heck they said, yeah right.
sorry but i disagree. that works on bikes on the street where the chain stays relatively clean. i've seen your video voodoo and that would kill a chain on your gravel and sand\silt dirt roads
you can buy a Grunge Brush. motosport and a few other dirt bike places sell them for about ten bucks. its a 3 sided poly plastic bristled brush that won't harm o-ring or standard chains plus it cleans 3 sides of the chain at once.
muddy as crap here and the brush is worth its wieght in gold for making easy cleanup of a nasty chain
