Well, it isn't that they won't work, I just find that the taper on these types of needles emphasizes a richer mixture. So, you end up moving the clip up to like the 2nd position.
Is there a real difference between a custom needle at the 2nd clip versus the stock needle at the 4th clip position? Boy, I can't tell them apart.
BTW, we jetted our 660 Raptors with GYTR needles, at the 3rd clip position, gave our stockers to a friend who set them at the 5th position, and his Raptor runs just a tad better than ours.
I just can't see spending the money.
