Rode up to the cottage on Friday for our holiday weekend, and back home this afternoon. ~300 km each way. Country roads for the most part, posted at 80 km/h (50 mph), and some city riding at 50 km/h (30 mph). Something like that anyways... Some traffic jams to contend with as well. The bike ran well on "pure gas "on the way up and delivered 4.31 l/100km (54.6 US mpg, 65.6 UK mpg). Had to fill up with E10 for the ride home and noticed the bike was running a bit lean (surging) at 1/4 throttle when cruising. Should be similar fuel mileage, based on the trip odometer and gas gauge. Going to raise the float levels 1mm and see how it does.
