Has anyone done any dyno runs on their wr450's. I reciently bought a 04 wr450 and Yamaha says they crank out 60 horse. I did the airbox mod and uncorked the exhaust and wound up at 33.9. Did the yz cam and then wound up at 35.3. Which is still way low from what Yamaha says I should have. The baseline showed 26.5 hp. I just would like to know if this is average or what?
