wow BiggerDanno thats a big difference, but then again its because of the variable error in the speedo, also the MPG calculator is wrong aswell. and Quijinn, thanks for your offer. I live in Houston TX so I know I am too far. I will take a closer look at the bike and the filter. 17k+ miles on the bike, had the bike since 5172k miles and have not changed the plugs. Is it easy to do? I will do it within 2 days if it is. I have the freaking PDF manual but its on another comp that is not with me. can I just remove the airbox?
