My son has a 2004 ltz 250,it started smoking,burning oil,most likely bad ring. Im familiar with rebuilding engines,just cant see paying 100 bucks for the service manual for the specs i need,such as head torque on the head,how much compression,valve adjustment.etc.. Cant find a cheap service manual on this bike. does anyone know the specs of this bike???

 

I am also interested in getting this information for my wifes new bike, anyone have the manual on disk? trade for the 660 raptor manual?
