As far as I can tell, and I have a small brain and heavy throttle hand, 17.4 mpg.
I am running similar numbers. Just finished a 4 day run down to Republic Washington and back. On the legs where I was spending most of the time around 64 mph (confirmed by GPS as indicated was more like 69) I was getting 4.8 to 4.9 L/100 km, which are 59 and 58 mpg Imperial. In a section where I was running about 70 mph with areas of heavy wind I got 5.3 L/110 km or 53.6. I had gone 331 km or 206 miles since the previous fill.Average 49 mpg on hwy. Highest was 56. I'm 5-9 and 190. Ave speeds of 55 to 70. Keep in mind this is based on an Imperial gal of gas; not US gal.
Initially on those settings I was getting about 41 US mpg. The catch was it was also colder weather still just coming off winter formulation for gas. The other part was it was short runs of a 100 to 150 miles with several full stops. Even with gentle acceleration from a stop the bike is thirsty.what should i look at to fix this? 31mpgs is not good at all.
i am definitely not beating on it. i am coming from 14 years of 600cc sport bikes. the ergos are competently different at a more sporting pace. putting around town; no big deal, but when i ramp up the pace, the ergos are not what i am used to. i am still trying to get used to the upright seating position with lower and more forward foot pegs along with a heavier, longer, taller bike.
i am not sure if this matters, but i am running with TC on sissy mode (3) and on the power mode set on whimpy.
what power mode are you running?I just got done with a 2100 mile road trip. I weigh in at a hefty 260lbs and I averaged about 41mpg over the duration. The best I got was 48.5mpg going through Rock Mtn National park but the pace was SLOW and traffic sucked. Spirited riding through mountain roads in southern Wyoming typically averaged 41-42mpg.
I'm working on losing weight but I think the mileage I got was pretty good for the weight I'm asking this bike to carry.
