You cannot compare the numbers on a Dynojet and stock jet. They number them differently. The Dynojet numbers will be smaller though they flow more fuel. If your machine is stock, you will most likely end up with a 144 Dynojet.

I took my DJ146 and my stock jet which is 152 to work and the stock jet's hole is larger.I had a machinest measure them for me.Mine seems to drag through the rpm's in 2 and 3rd gear,I may put the stock one back in using the dj needle and spring and see what happens I just don't want to lose the power too ride the wheelies.

Who knows why.. Maybe stock the rinny is jetted fat on top... Hard to tell since it's hard to get that slide all the way up anyhow. I wish I could put a camera in there to see how far up the slide actually does go, even with the dj spring.

I think you will find that the new needle is smaller in diameter and flows more fuel through the smaller size jet.
