I have recently been talking to the guys at my Florida kawi shop and I asked them if the 2009 instrument cluster would fit the other years ZX-10s because factory part numbers had not changed. They gave it some thought and came to the conclusion that if the part numbers are the same then yes they are interchangeable. Now, I just need someone who has access to a new 2008/09 cluster and another year's ZX10R bike to try it out and see if they are able to be interchanged. Anyone up for it? Anyone already do it? Please, if you haven't literally done it, I don't need to know. I got that opinion at Kawasaki already. Just the facts and a pic showing it in your non-2008/2009 bike. That's what I am asking for.
