My bike runs nicely at 220-230 until I hit the highway, then 250 it is. I'm going to look into notching my fender or a different one. I am also going to before I do anything, see what amsoil 20/50 does. I've had great luck with it. I may change the oil today, but my damn right wrist is so buggered up that I may wait. Note to self. BRPs do not come down from wheelies and stop like CRF250Xs do. Give self more time when doing so or bushes disapear, and wrists get severely sprained or worse.
