I have an 01 WR 426 that I YZ timed I am going to get a YZ needle but have a couple of questions. The 01 YZ comes with a EJP needle and in all the searches that I have done most of you are running the EKP. It seems that the 01 426 runs very different jetting. should I try the EJP of the EKP first? I know that you guys have explained this before. Is'nt one clip position the same for both needles?
