I have the opportunity to buy a 1982 1100 Aspencade. 58k miles. Older gentleman is asking 1500 but told me if I come get it this week that its mine for $600. Bike needs carbs rebuilt. Excellent condition otherwise, garage kept. I have 2 other bikes. What else should I be looking at on these bikes? Carb rebuild a pain? Ive done it on others. Please give a possible new Goldwing owner any advice you can.
