I tried Emailing dynojet. Every email address that they have listed on their site is no longer valid. I keep getting an undeliverable message. I also tried looking up FMF and their kit is only good for the 93+ Warrior, so it must be a dyno jet and there must be some reason its only good for a 93+ quad. I am going to have to call them and find out what is up. In the mean time, is there another jet kit manufacturer that you can recommend?
