my bike makes less noise the more miles i get on it. im only up to 7k but right around 4k the primary noise almost completely disappeared, it use to rattle alot around 1800rpms if i was kinda lugging the motor but even that is almost gone. switched to amsoil at5k and it got alittle smoother shifting but not by a lot.
