So I have an opportunity to buy an 81' CB750K from my brother in law for $1k. Debating if it's going to be worth it or should I just move on. It needs turn signals and the carbs tuned and synced. He bought it as shown in the pics years ago, so I don't know who did any of the work on it. Seat is horrible to sit on so it would have to change. If I buy it I might just get it running and sale it for a profit. Thoughts?
