I've been using one on my 2001 KX250 that I bought at the beginning of this year. The stock pull was a little harder than I liked so before the next trip out, I installed a Raptor lever. I've had great luck with it. Because of the longer pull, the clutch is slower to engage and disengage, but the easier pull is worth it to me. Those who have been racing a long time may not appreciate the slow clutch response, but the way I ride, it won't make much of a difference.
