My owner’s manual calls for R+M/2 or AKI of 86 or better. see Wikipedia http://en.wikipedia.org/wiki/Octane_rating . I often use 89 or mid grade because I can get it w/out ethanol. MY ‘84 CB650SC is “cold blooded” and requires choke to start and run for a minute or three or 6 before it runs well. I often forget to turn it off/push to the counterclockwise/up position, and ride for extended times with the choke on. Could that have been a factor? I usually get around 40 mpg around town if riding “gentle”, up to 45+ highway @ 60 MPH, considerably less if “hot rodding it”.
