I'd recommend just testing the machine first, and feel the clutch, to see if it feels like the clutch is snowmobiling ( Reving hard and slowly starting to grab) If your brakes work Fine, I'd recommend not touching them, The chain Will need it soon, just check how loose it is, if its really loose, you might want a new back or front sprocket too, for the plug, if it misfires bad, you might want to check that, and the stator to check for burned wires or broken soder. Oil change, i think that might be a given and it will need a new spark plug eventually anyways ( Dr8esl Ngk)
