top end

  1. ATV General Discussion
    I have a 2007 400ex with oil leaking from the top of the engine. Any suggestions as to what I am getting into for repairs? Thanks in advance.

    I got my hands on a 420 with lots of mods but sounds like it might need a new top end. What's the best top end rebuild kit to go with? I'd like to get a good high compression kit that would be best suitable for mudding. Any suggestions or anyone done a rebuild that would like to give input?
