They say a 07 comes w/#nhhu needle.mine had a#njbu which is an 08 needle.I am wondering how many needle # does the factory have. and what is the difference.I put the hrc kit on mine and my friend got an 08 but his hrc needle was a ngpr and mine was a nhvr.I think it is a conspieracy or something.:confused:
