Yo fellaz, I've got a 02 400ex with a Jet kit and a K&n filter.
I'm wanting to go to a stage 2 cam setup, is there anything else I need to change w/ this?

its just a drop in cam so put it in and your good to go but if you wanted you could change the rocker arms.

no need to do rockers unless yours are worn. I would suggest a high comp piston. a cam will give you a good increase alone, but is complimented very well by a higher comp piston.

piston is not that hard. could not find a like right off but if i find one i will post it. it is jsut removing a few more bolts and a clip or two.
Edit: here is a link on how to do a top end rebuild
