31/36L Zega Pro panniers, fuel cell and hydration jug on the top, CalSci Med screen with Yamaha wind wings, Rumbux system and some small LED lights in the wind I get 36-42 on average with mostly steady interstate riding. We have legal 80 mph here though, so lots of 70-80 mph. 85 mph and some headwind and I drop into the mid 20s pretty quickly. '12 with 103k on it. Freshened top end and new pistons/rings at 82k or so. Never have gotten as good of mpg since the repair work.
@BigBoy - Who did your flash and what did you ask for? Or was it on a dyno with the new exhaust?
