[engmedic]

I am wanting to install a 416 or 426 pistion on my 2002 400EX. Any one know were to find step by step instructions? I have never done this before but am fairly good with a wrench. I am currently running and FMF Powercore, KN, main jet 170, Piolt 45. I mostly ride the dunes. Any suggestions of which is better 416 or 426. Thanks

I have a 426 kit and most everything else I am very happy with it. I rips up piped Banshees at the hill the only down side is it is your last bore and next time you bore over you will need to purchace a new sleav
