I've got a 99 CBR900RR that I bought new, and noone besides me has ever worked on it. According to the Honda factory manual, it should have size 115 main jets, but it has 120's. Anyone ever run into this? I'm putting a Dynojet stage one kit in it, with a K&N filter, and according to the instructions I should use the 118 jets.Otherwise thebike is stock. Any input on this matter would be greatly appreciated! thanks
