    White is usually means "lean" one of those plugs looked like the rite color......light brown is good, do you have a reflash or Standalone? Id def look into a FPR or a powershot and not ride it like that

    Looks slightly rich but other than that everything else looks fine. Hooking a AFR gauge will let you know exactly were you are at.

    two and three run lean due to intake manifold design. 2 being the hottest because of cooling sytem design
