I got over 70,000 on a 99 and it runs better than the day I bought it. Longer change periods....for the filter too. My busa is a magic carpet. 1 up on the front sprocket...speedo is right on....44 MPG when I baby it....20 something when I ride proper...used Amsoil since 1000 miles. I don't know why I'm buying an 08...but I am.
