sparkk plug for 400ex
#3
get a NGK spark plug. i dont know part number, but just go down to ur honda dealership and they should have them. i dont think autozone and places like that will have them. i know here advanced auto didnt have the NGK for my CR, i had to go to a motorcycle shop to get mine. it will prolly be a little high though.

Standard spark plug number for NGK is DPR8Z and X24GPR-U is the DENSO number
Honda calls for a DPR9Z ( NGK ) or a X27GPR-U ( Denso ) for extended high speed riding.

You could have just pulled your plug out and gotten the number off of it! Unfortunately, there isn't any Iridium plug that is speced for this machine, so just use the standard NGK.
