A buddy of mine gave me a free dynajet kit. It also has the ncvq needle with it. The largest size jet in it is a 146. The way i understand it is dynajet numbers their jets different from Keihin carbs. Can somebody tell what size the 146 is compared to a keihin number? I've got an 07 450er.

you might want to research if it will perform right
