I recommend just buying the size jets you need individually. A lot cheaper than a kit.You should be able to get the size jets you need for a few bucks each. If your local Yamaha dealer isn't as useless as mine is they might have them in stock. You could buy a JD jetting kit for $80, and I've done this in the past to get the custom tapered needle (that's really what you're paying for), but I'm happy with the stock needle on the 09 YZ450.

Save you'er money call DR D ask them what they would run if you want to give you'r money away I send you my PayPal account send it to me I could use a extra $80.00 then I buy the the jets you need and keep the extra $75.00 for my self.

I will call Dr D my self easy $75.00 in my pocket.
