Hey folks I just bought a 2000 400ex. Extended a arms, axle, 450r shocks, hmf pipe, k&n filter, freshly rebuilt to 408. Pretty excited to get out and ride this thing. But its got a white bros rev box on it. Is that safe to run? I know white bros isnt the top of the line for rev boxes. Its also got g-force hubs on the rears. Ive been told they have a tendency to snap? I'll be doing alot of jumping so they'll take some abuse. Last question- whats the oil capacity on these?
