Get the bike started and let it get to full temp and see if it will not overheat. Once bike is warmed up put it in gear and hold the rear brake let clutch out and test the gear. Do that in EVERY gear. Check wheels for bends and look for RTV sealer on motor and around hoses. All that will really matter is the bike runs and works properly. Some of the wear and tear parts are easy to replace,but motors need to be in good working order.
