I currently ride 94 CR250 but looking to update. Was thinking of getting an 08 WR450f. But my mate has one its been jetted up, stock header with a whitebros tip and it runs shit, it stalls if you crack the throttle any faster then my nana could, and very sluggish down low my cr dominates it. I rode a stoke klx450 and shat all over it though the complete rev range. I also rode a 2003 WR and it shat all over the 08 aswell, just wondering has yamaha got it all wrong this year or is it a 1 off shit box.
