I just returned from a little ride from La Pine Oregon to Klamath Falls. 221 miles round trip. Total fuel consumption 4.2 gallons. I'm running 89 octane gas. Riding at about 70 miles per hour I've been getting around 50 miles per gallon. With 87 or 92 octane I get no better than 42 miles per gallon. If you have not tried mid range gas give it a try it may improve your mpg. My bike is a 2009 so it has fuel injection. I love the milage. My 1100 never got milage this good.
