If it slips on the sprocket it is probably too late to just adjust it and be finished. If you plan on doing your own maintenance the first thing you should do is get a service manual and get familiar with it. You will find all the info you need in there on adjusting your chain as well as other maintenance items that you could do yourself instead of paying a dealer to do it for you. It will also tell you how to identify a sprocket and chain that are in need of replacement.
