federal law mandates the 10th digit of a serial # reveals year model. your serial # posted is incorrect, 4 =04, 5=05. this supercedes any color matching or any other factor used to determine year model.
With most Japanese bikes, the VIN and engine numbers will be within a couple hundred of each other at most. So if you have frame number 3000 and engine number 15,000 then you know its not the original. There are some exceptions to this but it is a fairly accurate way to tell with most bikes.
