That's way too much fuel burn. Long term this will do damage to the engine in the form of washing the cyls of oil and overall oil dilution for the rest of it. Thinned oil won't be bearing friendly. From what I've seen over the years, anything below 30 would be reason to investigate why. In the real world there is no point in checking for MPG if on is constantly bouncing off the rev limiter so cruising is the only meaningful checks. 25 mpg can happen but this isn't important for actual mpg. 9/10 it's from a shit tune or a piggy back device that feels the cure all is to throw gobs of fuel at a problem. For what it's worth the factory claims 38 mpg US for the stock bike.
