I have a 99 Warrior and I have installed a K&N air filter, Dynojet jet kit and White Brothers E-Series exhaust. My problem is with the White Brothers my Warrior starts off idle. So I put on my stock and now my Warrior when you take off feels like it has no power at all on the bottom. Could I need to adjust the needle and pilot jet?

 

Im pretty sure it is the pilot air screw that you need to adjust. Ive got the exact same setup on my '94 and i had the simular prob. There should be some paper work in your k&n jet kit that tells you how to adjust the screw. It is located directly on teh bottom of the carb.
