I get between 43-48 mpg with mixture of city/highway commute to work. Haven't been on a strictly long highway trip yet. Have one planned this spring. Between the highway miles and larger front sprocket I recently installed, I expect mileage to be in mid 50's. I'm pretty easy on the throttle.
Other than your right wrist, your weight, how tall (more wind resistance), tire pressures, head/tail winds, and how smooth your ride, average speed etc etc. I get around 45mpg (US gallon), 34 seems a bit low, but think of it this way, if you were on a bigger bike it would be even worse!

You create a login and set up your vehicles, then you use the site as your log when you fill up. It keeps all your stats for you, and best of all lets you compare against everyone else with your same model.
When I fill up, I always enter my trip, gallons used, and price per gallon on my phone. Just make it a habit. They also have a mobile version of the site for phones. You can bookmark the fillup page on the homescreen of an iPhone too, and it basically becomes an app.
My best was 53 mpg, then I put a Givi windshield on and added soft bags, switched to a 16 tooth front sprocket. Most of my riding is in 6th gear at 65 mph and I get about 47mpg. If you idle till the rpm's drop on warm up, and run over 5,000 rpm's all the time, I expect you will never get over 45 mpg.
