I'll look for the pics I took, but to make them fit properly you have to grind a little bit on the valve cover. It's not really a big deal. They will fit without doing it, they just won't reach down far enough to make as good a contact as I'd like. I ran the car for a long while without modding the valve cover at all, so you may get lucky. Any year from the first CBR600 to the current models should work. I think mine were from a 2005 or something.
I'll get those pics. Stay tuned.
