[QUOTE="YZcarver, post: 51945, member: 744"] [URL]http://www.fmfracing.com/Content/Instructions/Jetting/YZ250%20jetting%20%28000346%29.pdf[/URL] The pilot only controls the very bottom, like idle to barely cracked. From there it is all about the needle until you are wide open. Don't forget about your airscrew as well. Do 93's have a powervalve? If so, is it in good working order? If it was sticking, that would explain a lot.
