Great looking ride! Perhaps a pair of saddle bags to throw over the carrier for short runs to the store. I wouldn't worry too much about the rag joint sprocket mount(if you took the time to get it true). I have several bikes with mucho-mucho miles on rag joints. Also I hope you don't intend on going 40 mph(both of us being seniors, we have better sense). Back to the subject, Your ride looks great. The craftsmanship and pride wo worksmanship shows. Can't wait for the warm weather to burn up the back roads!
Hello and welcome to MB. Just curious if you wouldn't mind sharing closeup pictures of your motor mounts ?
