Need help I have 17 yz125, vr4 reeds, FMF FATTY AND SHORTY, 93 octane with 32:1 yamalube, stock jets I ride in Southern California. bike runs great no bogs at all with stock pipe and shorty, Im about to put on a FMF fatty and I bought a JD Jetting kit cause I have been reading on the forums a lot and some say you need to re jet and some say you don't, just want a opinion from someone in the same area. gonna do that this weekend and mess around with it see if I can figure it out but I would appreciate the help thanks guys
