Does anyone know what the difference between a 99 250 EXC and a 00 300 EXC rear shock is? My buddy has a 00 300 EXC and the ride is much more plush than my 99 250 EXC. I know the forks are different but the rear of his bike is much softer.I'm guessing that it is in the shock valving, both bikes are stock.:think I'm considering changing the shock valving but I want to make sure that's what it needs. The sag both static and race are set properly on my bike. I ride tight woods stuff, weigh 200lbs with gear and am a B rider. Any suggestions or comments?
