I finally am in the testing stage for my minibike, and today while I was taking it up and down the street I saw this black grease or oil by the chain. Everything on the bike is brand new including the engine, so I'm guessing it's being slung off either the chain or the clutch. Is this a normal thing to see or is this something I should be worried about? The bike was running fine, but the chain is pretty loose and popped off once since this new engine sits farther back than the old one.
