i have 99 zx9r, i was upgrading to a 01 frame bc i like the bolt on subframe, i read a couple of places that everything would bolt up no problems, yeah right!!!, here is my problem the pivot bolt hole on the frame is bigger in the 01 than the 99,its about $20 for the new pivot bolt,thats ok, but will i have to change the bearing and screw block also, any help would be appr., thanks
