check FMF's web site for jetting faq, think they'll say 132main and advise a clip position for the stock needle if I remember right

Thanks RimBender- I looked it up and they do recommend 132/35 with a N1TC (3rd clip) needle, so they're listing Keihin jet sizes not DJ sizes. They only say to use the stock fuelscrew - not how many turns out. Anyone know?

This method also gives you an indication as to whether you have the right pilot jet or not.
