Thinking back about the early days of Japanese bikes, over heating wasn't really a problem until they started making bikes over 1000 cc's. I believe that is when we started getting water cooled motorcycles. I remember the first bike that really gave me problems with over heating, that was my XS1100 Yamaha. It was air cooled and did not have a oil cooler. So I would assume the oil cooler is a necessity on the CB1100 for reliability. Nothing worse than having your bike shut off in traffic from over heating. It happened to me quite a few times on that XS1100. I think it would be a big mistake removing the oil cooler on the CB1100.
