I am looking at a 1987 goldwing aspencade with 50.000 miles on it. Does this bike have carbs or is it fuel injected? Is this or was this a good model to own? Is 50K too many miles? What is the pro and con on this model? Are after market parts available?I don´t know what has or has not been done to this bike. Thanks for your help. Deacon 29
