Usually, just after I buy a used motorcycle, I spend several hours un-doing "mods", and cleaning. Cleaning usually entails, among other things, taking the front sprocket cover off. I've seen the sprocket cover so full of gook, that the chain is the only thing preventing more from being piled on. Then that nasty black goo weeps out, and gets flung backwards, and make an even bigger mess. I'll stick to WD-40 and John Deere All purpose Spray lube. If I have to replace the chain a little sooner, so be it.
