Hmmm, oddly enough I've just started the same quest. I was actually hoping I would contact someone in AUS and have them send one over - because in 07 Yamaha had a White Kit available:
It did exist at one time. Our Yamaha Dealer network in the U.S.A can see which dealer has a specific part number in stock - so you best bet is going to be through a Yamaha Dealer who's willing to work some magic.
Let me know if you track it down - I'll buy one, too!
