Is this when cold? Both of my kids 02 Scrambler 90's are like this until the choke is off. If it is sluggish after warm up them I would take another look. Also, the the 03 Pred 90 is suppose to have a manual choke. Make sure it is off.If you still have problems find Jon Anderson A.K.A. (Raptor 720) at ATV Connection, he is a great contact for youth quads.
