new to the forum and may be pruchasing quad

hello I am new to the forum here as stated and may be purchasing a 99 fourtrax 300 4×4. Its been sitting in a barn for who knows how long. id like to get it running and drivable but am unsure what to check besides basics as it’d be my first 4stroke machine. besides oil, plug, carb, filters ect., what should I be concerned with? any help would be awesome! oh and it’d more than like only be picked up for a couple hundred bucks which I feel would be worth while getting back up to good shape. and last issue he knew it has was something with the rear end he was unsure of what.
