    Since you have an open airbox and full system, I would go with a 165-170.

    I've got a '03 400ex with 11:1 wiseco, stage 2 hotcams, a full system biggun, rev limiter, and a K&N airfilter and i also run with the airbox open. I run a 170 and it works fine.

    what kind of jets will you be using, keihn or dyno jets?
    and do you know about what your altitude is where you live?
