I finally got to ride my 400ex after I got all my goodies installed. The power ups are in my Signature. Wow that baby is fast the mechanic at the Honda shop said the power band is as fluent and powerful as the new 450R. I'am very impressed he told me to take it pretty easy for the first 20HRS then go in a adjust the valves and check the rockers. What do you guys think do you think I'll have a problem with my rockers. WhiteBrothers recommended hard faced rockers I'am not sure if I need them or if they just say that to cover there butts if something happens if anyone has a opinion let me know. Thanks
