I own this very year and make. If I were you I would be all over this bike if you can get it for a reasonable price. There was only one flaw with this bike IMO, the piece of shit mikuni tmx carb it came stock with. Take my word for it, DO NOT spend any time or money trying to jet it. No matter what you do it will not run correctly for very long because of varying temps, altitudes and humidity. I have been riding for 30 years and have never had such a frustrating time trying to jet a bike before. So that being said, go to e bay and buy a used 38mm keihin pwk off a 05 or later yz (i got one shipped to my door for 42 bucks) leave the tps disconnected, jet accordingly and kiss all jetting and poor performance woes goodbye. If honda would have speced this carb with this year cr it would have won all the shootouts it was in. This one mod on the 04 bike makes it run clean from top to bottom, its that big of a difference.
