Im pretty sure most yamahas of that age will have the same cap mate......i wouldnt bet my life on it my just that my 08 thou looks like it has the same one...i think stuff like that is standard issue...for example i used a sump p,ug from my old 600 on my thou...exactly the same.
I actually do have a 600 cap somewhere ut i just dunno where abouts in my shed it is & havent seen it in years but if i can find it ill let you know.
