Ok, look, I've asked before, but, not much help. I have almost 8900 miles on my 05. All I've changed up to now is the oil. My buddy has an 05 as well. I started out last season riding hard MOST of the time, and getting around 180 miles to the fill up. Now, I ride hard ONCE in a while, and am getting 119 to this last tank. What the **** HAPPENED?????????? I am heavier than he is by 70 pounds or so. But, he get's the mileage I USED to!!! And he only has around 5k miles on his! Thanks for the input!! PLEASE help!!!!!
