I did a trip from St Petersburg and back on a CB 750 in, I think 83, on a 79 mbike. Those things eat chains. On a three thousand mile trip I used up a chain and sprockets that were new when I started I crawled back to St Pete at 15 mph the last 100 miles or so with the chain stretched as tight as possible because there were only little nubs for sprocket teeth. My Virago ten years later had an enclosed chain that rode in 5 tubes of grease. I put 70k miles on that chain.
Sorry, that’s St Petersburg to Omaha.
