Hello everyone. I just found this forum this evening and I'm going to look at a 85 xl600r tomorrow night with 12,000 miles on it for $1500.00. He says it's in excellent condition and runs "great". We'll see. I would use the search function to have my questions answered but I don't have much time. Sprockets and chain have been replaced along with the fork seals and wheel bearings. I know it depends on how much their abused but how many miles can you get out of these engines before they need rebuilt? I would greatly appreciate any advice or suggestions as to what to look for on this bike. Thanks.
