Cam changing

[josiah400ex]

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?

[Franky G]

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.

[josiah400ex]

rocker arms? r those drop in to?, no tuning needs to be done?, and what kind of performance gain am i looking at with this...

[underpowered]

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.

any links here on how difficult it is to do a piston change?

[underpowered]

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

i put in a stage 1 cam, wiseco 11:1 piston at the same time and was very impressed at the difference, like night and day
