It looks like I will soon be picking up a 2006 WR450. I am traiding my Jeep Cherokee for it. The bike supposed to be fairly low hours but I dont know if the factory speedo/odometer has an hour meter. The bike is all allegedly all stock. I will see it in an hour or 2. I guess my first question is what are problem areas with this bike? I have read about modifying or replacing the the throttle stop and also exhaust modificatoins and rejetting. My current bikes are a 2004 CRF250X which I love, My 2002 KX250 which I also love. This will be my first time owning a Yamaha dirt bike. I did used to have a 2006 Raptor which my wife and daughter rode. I will probably be selling one of my bikes as when this trade deal came up, I was mainly trying to sell my Jeep.
