Anyone know what lenght the throttle stop should be on a 2000 WR400? I bought this bike used and never checked to see if it was cut down to the proper lenght. My bike won't hit the rev limiter in 5th gear and even feels pretty flat near the rev limiter in 4th too. I'm running stock gearing and don't really wanna change to lower gearing either. It's already low enough and spins the tire too much on loose, sandy hills as it is. The more I look at this thing the more I think my jetting is pretty close to right. Anyone think I'm on the right track?
