There seems to be a few after market parts there. Deffinately a cover on the tank but I have an extra green one for you if you need. Looks like carb and air cleaner too and shock, wheels, extended axle or spacers, and water pump and stator cover. I would imagine a new stator and flywheel but ask about that because they are know to go. I would do the trade but take it for a ride and make sure everything operates fine and it goes through all the gears. Looks like a deal in my book!
Just sit back and chillaxx
