i am thinking of buying a 1981 goldwing but it will not run smoothly without the choke being half on,this machine has been stored for 3 years and the present owner says that one of the carbs has some schellac build up in it.I am a complete novice at this and am concerned that i am being led down the garden path.The asking price is 1200.00 dollars american,is this a reasonable price?
