I am new to modding my quads, but i want to make my new to me 2000 400ex a trail monster. It already has a white bros pipe, dynajet kit (junk), kn filter with prefilter and lid removed, and.......elka shocks. What else should i get for it to up my performance for cheap. I am more concerned with reliability than absolute performance. I am thinking that sparks ignition key and a rev box.....but u guys know more than me. I got some money to spend and am ready to make it perform. I definately want anything that will make my throttle respond better like the 09 EFI Z400.
Thanks guys.
