Took off the front sprocket cover so I could clean the chain, and because I'm one of those curious people that likes to see how things work.... usually I can't get things back together but I was fine this time. Anyway, took off the cover and this is what I see caked up to the chain Went at the crud with a toothbrush and some good ol' fashioned WD-40 It didn't look too bad until I started taking out giant clumps, it was crazy. Anyway, thought someone would get a kick out of this.
