I have noticed that the longer I have had my bike the lower the gas milage it is getting. When I first got it I could usually get around 37 or so but now I am getting 31 or 32. Is there anything wrong with these numbers or am I just sucking up the gas as I get used to rideing her harder. I have an 03 Silver/Gray (fastest) bike. Only mods being a TRE and a Pair mod. I switch between premium and regular gas depending on how much Is in my pocket that day. I live in Lower Alabama so it is around 80 to 90 hear and pretty close to sea level. Let me know what everyone else is seeing and if there is a problem with my numbers what might it be?
