Earlier today i was out riding and i came across a wide open field. Like any other rider would do, i let my bike go all out. It pulled really good, until i got to 5th gear. Then it started feeling like the clutch would slip a little then get grip, then slip again and so on. But if the clutch WAS slipping, wouldnt it slip for all the other gears too? I just got this bike it is a 2003 Yz 250F
