I just bought my first bike for from a farmer in Wisconsin. A blue 1975 RD200 with 1200 miles. The bike is in great condition, no rust even original tires. Looks brand new, was parked in a barn for 20 some years. I stared it and it turned over, but stared making a loud squealing noise. It is really a cool bike so I just had to have it. The farmer sold it to me for $200 because of the strange noise the engine was making. I hope it did not waste my money. Just wondering if anyone knows what might be the problem and how much to fix? Also, what it might be worth after it is runnning smoothly. I hope to ride it this summer. Thanks!
