    Help! Phantom Engine Problem with 450er

    Well . . . I figured it out. A bit embarassing actually. This is the first 450 I have owned. My previous quad was a 1988 250r two-stroke. The 2-strokes had a solid airbox lid and a snorkle for air intake that connected to the front of the airbox. Unbeknowst to me, the 450 breaths through the airbox lid. Whoever had this bike before me apprently lost the stock airbox lid and replaced it with one from a quad that had a air intake similar to the 250r. So . . . it was simply running out of air. Once I backed up and took a look and figured out that there was no way for air to get INTO the airbox, it was an easy fix. I cut a 2x2 flap in the back of the solid lid to let some air in and the 450 runs like a raped ape now! Amazing how we tend to overlood the obvious in search of the more complicated. Thanks for the input.

    Help! Phantom Engine Problem with 450er

    I just got it. It wasnt running when I got it. The wiring harness was melted. I replaced the harness, stator, cdi and coil. Since you mentioned airbox . . . it does have the incorrect airbox lid which doesnt seal off good. I will give that a try today and see what happens. Thanks for the tip!
  3. I have a 2006 TRX450er. The quad starts and idles fine. It seems to run ok at low to mid RPM but when I accelerate hard, it "falls on its face". Basically, it acts like it is dying. I can slowly acsellerate in 1st or 2nd gear and actually get the RPM's to build higher than they are when the dead zone occurs. Its only when I am accelerating hard. If I go up through the gears quickly, it will usually start at about half rev in 3rd gear. I can hold the throttle steady once the first dead spot hits and it will catch back up and then die again over and over until I let out of it. Its like its running out of power/fuel and then catching back up. It feels like an electrical miss, but I have changed the stator, CDI and Coil and I still have the same problem. Any ideas?
